INTRODUCTION. 
 
 By C. V. Riley. 
 
 The following catalogue of the exhibit made by the Division of 
 Entomology, Department of Agriculture, for the World's Columbian 
 Exposition at Chicago, has been prepared with a view of increasing 
 the usefulness of the exhibit from an economic and educational stand- 
 point, and is intended to supplement the exhibit by giving such infor- 
 mation regarding each separate item as the articles themselves do not 
 convey or which it was impossible to give upon the limited space of 
 the labels accompanying each specimen or article exhibited, though 
 these have been made as full as circumstances would permit. In the 
 preparation of the catalogue and of the exhibit itself I have had the 
 aid of Mr. C. L. Marlatt, who has been particularly charged A\ith the 
 work, and whose assistance I take pleasure in acknowledging. 
 
 The exhibit of the division is intended to illustrate the work that 
 has been done in applied entomology, viz, the investigation of the his- 
 tory of injurious insects and the devising of suitable remedies to pre- 
 vent their injuries ; also the work of building up and maintaining a 
 large and valuable national collection of American species, and inci- 
 dentally the representation of exotic insects for purposes of compari- 
 son. The intimate connection of the Department of Insects of the 
 National Museum with the Division of Entomology has justified me, as 
 honorary curator of said Department in the National Museum, in com- 
 bining this last feature with the exhibit of the U. S. Department of Agri- 
 culture, and, to avoid duplication, I have, with Prof. Goode's approval, 
 confined the Museum exhibit to an exposition of the characteristics of 
 the families of American insects. 
 
 Certain prominent and interesting exhibits of an entirely novel 
 character in the line of entomological illustration have also been made, 
 the leading features of which are wax models of the host plants. 
 While a number of plants have been thus modeled, I have designed 
 to thus represent, more particularly two of the most important and 
 characteristic of the economic plants of North America, viz, cotton 
 and Indian corn ; and one, which, as the most conspicuous and wide- 
 spread of the floral forms which add beauty to our autumn scenery, is, 
 
 7 
 
perhaps, the most characteristic from the aesthetic side. I refer to 
 the Golden Rod, which is also of great entomological interest from the 
 vast number of insects which either nourish from it or are attracted to 
 its bloom. 
 
 Another feature of the exhibit is a rather extensive and very showy 
 collection of insects, chiefly South American, which is presented to 
 give some idea of the nature and extent of the insect fauna of the 
 tropical regions of this hemisphere. Many of these species, collected 
 by Mr. H. H. Smith, are unclescribed, and as the names of these exotic 
 forms would be of little service even where they could be given, and as 
 they are exhibited for other reasons, no attempt has been made at 
 classification or determination. This is to form the showy portion of 
 the exhibit, and, with the Solidago display, appeals to the love of the 
 beautiful in contrast with the remainder of the exhibit, which is scien- 
 tific or educational and has been arranged with little regard to artistic 
 effect. 
 
 The exhibit is made up of the following sections : 
 
 Section 1. — Insects Injurious to Agriculture. 
 
 This section of the exhibit comprises some 602 special exhibits, each 
 of which is an object lesson and pictorial epitome of the life history of 
 a single injurious species, including as far as possible the different 
 stages of growth of the insect; the injury it does, with specimens; 
 its enemies and parasites; the available remedies and preventives, and 
 references to the chief articles where full information may be found. 
 These references are principally to Government and State reports to 
 which the farmer is most likely to have access. These exhibits are 
 grouped together according to the plants or animals affected, and relate 
 solely to orchard, field, and garden crops, the parasites of domestic ani- 
 mals, and household pests. A small representative collection of cases 
 of insect enemies to forest trees has also been added. 
 
 Supplementing the above are exhibits representing specially injurious 
 species of prime importance affecting particular crops, which are ac- 
 companied by wax models of the plants, showing the injury in contrast, 
 for the most part, with models of the perfect plants displayed alongside. 
 Noteworthy in this series are the special exhibits of the Hop Plant-louse 
 (Phorodon humuli), and of the Chinch Bug (Blissus leucopterous), which 
 include greatly enlarged models in papier-mache of the insects in diff- 
 erent stages. The Fluted Scale {leery a purcliasi), which has been so 
 prominent of late years in California, and its principal enemy, the 
 Australian Ladybird ■ (Vedalia cardinaUs), which has so throughly 
 destroyed or controlled the scale, are also represented in this series, 
 together with enlarged models of the Yedalia. A number of anatomical 
 models made by Dr. Auzoux (Paris), representing the Silkworm and 
 Moth, Honeybee, and Cockchafer are also exhibited. 
 
Section 2. — Systematic and Biologic Entomology. 
 
 This section of the exhibit is illustrative of the national collection, 
 which is under my charge as honorary curator of the Department of 
 Insects. It consists of a series of drawers representing samples of the 
 systematic collection in different orders, and also of sample drawers of 
 the biologic series, systematically arranged, representing the full life- 
 history of the species which have been studied, whether of economic 
 importance or not, and these will be interesting more especially to the 
 student or professional entomologist. T'rese are exhibited not as com- 
 plete series, but as samples taken from the actual collection to illus- 
 trate the methods employed in the arrangement of the regular system- 
 atic and biologic series, and also to give the visiting entomologist an 
 insight into the present status of the national collection. With this 
 section is included the showy exhibit of insects chiefly from South 
 America, referred to in the introductory paragraph; also the special 
 exhibit of the Golden Eod with the insects which affect or frequent it. 
 
 Section 3. — Silk Insects. 
 
 This section includes a biologic exhibit, in some cases with specimens 
 of the raw silk, of the more important native and foreign Lepidop- 
 tera, the larvae of which spin silken cocoons, and which are or may 
 be of value as commercial sources of silk. 
 
 Section 4. — Professional Exhibit. 
 
 What has been thus denominated is an exhibitof the apparatus used by 
 the professional or the amateur entomologist in the collecting of insects 
 and in their mounting, rearing, and preservation. This includes a full 
 display of all the ordinary apparatus used for these purposes, of chief 
 interest among which will be the series of different devices and methods 
 for rearing insects, comprising a large variety of cages or vivaria, and 
 breeding-jars of all sorts. Many of these are fitted with wax plants 
 and insects, showing the exact methods followed in the work of the 
 Division. This section gives a complete illustration of the implements, 
 apparatus, and methods of work of the practical entomologist. 
 
 Section 5. — Insecticides. 
 
 This section comprises insecticide preparations which have proved 
 of value in the work of the entomologist in the prevention or de- 
 struction of injurious insects. To make the exhibit as complete as 
 possible some of the more valuable of the patented articles have also 
 been included. The first part of the exhibit includes the important in- 
 secticides not covered by patents, some eighty samples being shown, of 
 which a dozen or so are of supreme importance and fulfill all ordinary 
 needs, the others being of only occasional value. The proprietary and 
 
10 
 
 patented articles are exhibited without comment, for the reason that all 
 practical requirements in the way of remedies are met by the use of 
 unpatented substances shown in the first portion of the exhibit. 
 
 Section 6. — Machinery. 
 
 In this section are included the more important nozzles for the appli- 
 cation of liquid insecticides and a few of the leading insecticide ma- 
 chines, the latter collection representing some typical forms, special 
 prominence being given to the knapsack sprayers, and no attempt be- 
 ing made to show make a complete exhibit of all insecticide machinery. 
 A feature of the nozzle exhibit is a series of trial nozzles which were 
 made in the elaboration of the principle of the cyclone or eddy-chamber 
 spray nozzle, which, with its modifications, is now in such general use 
 in all parts of the world, and the original type of which has come to be 
 known (against my own inclination) as the Eiley nozzle. 
 
 Section 7. — Official Publications of the U. S. Entomologist. 
 
 This section includes as complete a file as could be secured of the 
 official entomological publications issued by the national government, 
 and comprises both the work of the Division of Entomology of the 
 United States Department of Agriculture and of the United States 
 Entomological Commission. 
 
 Section 8. — Illustrations, Maps, and Charts. 
 
 An exhibit has been prepared of all the entomological illustrations 
 which have been published by me in an official capacity, either as 
 State Entomologist of Missouri or as United States Entomologist, and 
 also as chief of the United States Entomological Commission. These 
 are grouped in two series • one, illustrations of North American insects, 
 mostly from my reports on the insects of Missouri, and from my own 
 drawings ; the other, illustrations of North American insects, mostly 
 from drawings made under my supervision by Miss Sullivan, in the 
 Division of Entomology, U. S. Department of Agriculture. The illus- 
 trations of machinery which have been published by the Division and 
 by the Entomological Commission, are also included in this section, 
 but are exhibited separately with the exhibition of insecticide machin- 
 ery. All these illustrations are mounted on large sheets, and have 
 references to the publications in which they are fully described. With 
 this part of the exhibit is also shown a series of maps and charts illus- 
 trating the range of important injurious insects on this continent, and 
 a number of large solar prints illustrating the classification of insects, 
 by means of charts representing the different orders and suborders by 
 typical insects in their different stages of development. There are 
 also charts of special injurious species, together with views represent- 
 ing the practical application of insecticides, and interesting views of 
 
11 
 
 insect depredation. Most of the charts are photographed from originals 
 used in my lectures more than twenty years since, and do not indicate, 
 so far as classification goes, some of the later views adopted. Still 
 another series gives interior and exterior views of the insectary of the 
 Department, and interiors of the entomological rooms in the Depart- 
 ment, and the National Museum. 
 
 The whole exhibit is intended to illustrate primarily the nature of 
 the national collection of insects and the methods of work followed in 
 the IT. S. Department of Agriculture, and I have felt in preparing it 
 that such a collection would be most likely to prove unique and not in 
 any way duplicate what the different States as such may do in the same 
 line.

 SPECIAL EXHIBIT OF MODELS OF PLANTS AMD 
 
 INSECTS AFFECTING THEM. 
 
 603. INDIAN CORN, OR MAIZE. 
 
 Zea mays. 
 
 A hill of ripening corn reproduced in wax is exhibited as a center 
 piece about which to group the insects affecting this crop, 129 distinct 
 corn enemies being represented in the accompanying cases of the eco- 
 nomic exhibit. The corn plant is chosen and thus fully treated as rep- 
 resenting the most typical of the cereal crops of temperate North 
 America. The insect enemies represented in the surrounding cases are 
 treated separately, but arranged according to the nature of the injury 
 they do to the corn plant, namely, as affecting the root, stalk, leaves, or 
 ears. Each insect is shown, as far as possible, in its different stages, 
 together with the injury occasioned by it. Eemedies are given and 
 references made to the chief literature. (See Eos. 202-330.) 
 
 604. COTTON PLANT. 
 
 Gossypium lierbacewm. 
 
 A hill of ripening cotton reproduced in wax is exhibited as a center 
 piece about which to group the insects affecting this crop, some 36 dis- 
 tinct cotton enemies being represented in the accompanying cases of 
 the economic exhibit. The insect enemies represented in the surround- 
 ing cases are treated separately, but arranged according to the part of 
 the plant they injure, namely, stems, leaves, or bolls. (See Eos. 
 331-367.) 
 
 605. COTTON WORM. 
 
 Aletia xylina. 
 
 Model in wax of a portion of the cotton plant, showing character' 
 istic defoliation of the leaves resulting from the attacks of the young 
 or mature larvae. (See Eo. 341.) 
 
 606. COTTON BOLL WORM. 
 
 HelioiMs armiger. 
 
 Model in wax of a portion of the cotton plant showing injury oc- 
 casioned by the larvse of the boll worm to the leaves, squares, forms, 
 and bolls of cotton. (See Eo. 358.) 
 
 607. GOLDEN ROD. 
 
 Solidago sp. 
 
 Model in wax of a clump of Golden Rod with a number of the in- 
 sects which commonly frequent it disposed on the bloom, and an ac- 
 companying exhibit showing the wide variety of insect life known to 
 breed on it, and also the insects known to frequent it commonly for 
 the honey and pollen. 
 
73 
 
 608. HOP PLANT-LOUSE. 
 
 Phorodon humuli. 
 Unaffected Hop Plant. 
 
 A spray of hops, modeled in wax, representing the plant as it .ap- 
 pears in vigorous growing condition, and free from the attacks of its 
 principal enemy, the Hop Plant-Louse, to contrast the stronger foliage 
 and more abundant and larger hops produced by plants from which 
 the hop louse has been eradicated by the use of proper remedies. (See 
 No. 198.) 
 
 609. HOP PLANT-LOUSE. 
 
 Phorodon liumuli. 
 Affected Hop Plant. 
 
 A spray of hops modeled in wax, representing the vine as it ap- 
 pears when attacked by the Hop Plant-Louse, showing the blackening 
 and discoloration of the leaves and the small and inferior hops, which 
 are also discolored and otherwise unsuitable for market. 
 
 610. HOP PLANT-LOUSE. 
 
 Phorodon humuli. 
 Winter eggs. 
 Enlarged model in papier macke" of the winter eggs, which are at- 
 tached by the sexual female to the terminal twigs of the Plum, in crev- 
 ices around the buds. 
 
 611. HOP PLANT-LOUSE. 
 
 Phorodon humuli. 
 
 Stem-Mother. 
 • The stout female plant-louse shown in this papier mache' model 
 hatches from the winter egg and is characterized by shorter legs and 
 honey-tubes. It gives birth without the intervention of the male to 
 living young, of which three generations are produced on the plum 
 tree, the last being winged and migrating to the hop. 
 
 612. HOP PLANT-LOUSE. 
 
 Phorodon humuli. 
 Winged Migrant. 
 This model represents the first winged generation, the third pro- 
 duced on the Plum. It instinctively flies to the hop plant and is the 
 progenitor of from five to twelve wingless generations of virgin fe- 
 males, which people the hop plants until autumn and are the sole 
 forms which depredate on the hop. In autumn the last generation pro- 
 duces again winged females, which fly to the plum trees. 
 
 612a. HOP PLANT-LOUSE. 
 
 Phorodon humuli. 
 Hop-affecting stage. 
 
 This model represents the structure and appearance of the five to 
 twelve wingless generations of virgin females which people the hop 
 
74 
 
 plant until autumn. These are the progeny of the winged migrant (see 
 612), and are the sole forms which injure the hop. 
 
 613. HOP PLANT-LOUSE. 
 
 Phorodon humuli. 
 Return Migrant. 
 
 This model represents the last generation produced, on the hop, the 
 winged migrant form which in September returns again to the plum 
 and gives birth to three or more young, which are the true sexual 
 females, the first perfect sexual females produced in the cycle up to 
 this point. 
 
 613a. HOP PLANT-LOUSE. 
 
 Phorodon humuli. 
 
 Pupa of Return Migrant. 
 
 This model represents the pupal stage of the return migrant. The 
 striking features are the wing-pads, which with another molt become 
 the ample flight organs seen in the model of the adult. 
 
 614. HOP PLANT-LOUSE. 
 
 Phorodon humuli. 
 
 True sexual female. 
 
 This model represents the generation born of the return migrant, 
 which never acquire wings and never leave the plum tree. Maturing 
 in a few days, according to the temperature, they are fertilized by the 
 true winged males which have been subsequently developed on the 
 hops, and have come from the hop fields to the plum. Shortly after 
 fertilization the winter eggs, with which the cycle started, are deposited. 
 
 614a. HOP PLANT-LOUSE. 
 
 Phorodon humuli. 
 
 Young sexual female. 
 
 This model represents the newly batched stage of the only perfectly 
 developed sexual female produced in the life cycle of this insect. For 
 the adult of this stage see Exhibit No. 614. 
 
 615. HOP PLANT-LOUSE. 
 
 Phorodon humuli. 
 
 Winged male. 
 
 This model represents the first and only male generation produced 
 in the life cycle of the Hop Plant-louse. This is developed in the 
 autumn and flies from the hop to the plum and fertilizes the true sex- 
 ual females. 
 
75 
 
 616. HOP PLANT-LOUSE. 
 
 Phorodon humuli. 
 
 Bemedies and preventives: The attacks of the Hop Plant- 
 louse may be prevented very satisfactorily by first destroying all the 
 wild plum trees in the neighborhood except a few which may be left 
 for trap plants. These latter should be sprayed with strong kerosene 
 emulsion in September to destroy the return migrant and its progeny, 
 and also the winter eggs, and again in spring to reach the two or three 
 plum generations which may have developed from eggs escaping the 
 fall treatment. Secondly, by destroying the hop plants as soon as the 
 crop is gathered. Thirdly, and perhaps least effectively on account of 
 the difficulties attending the treatment, spraying the hop plants with 
 kerosene emulsion diluted about ten times. Fourthly, spraying the 
 affected hop plants with a dilute decoction of quassia chips. 
 
 617. HOP PLANT-LOUSE. 
 
 Phorodon humuli. 
 
 Eemedy : Kerosene emulsion. 
 
 Kerosene gallons. . 2 67 per cent. 
 
 Common or whale oil soap pound. . i 
 
 Water gallon.. 1 33 per cent. 
 
 Heat the solution of soap and add it boiling hot to the kerosene. 
 Churn the mixture by means of a force pump and spray nozzle for five 
 or ten minutes. The emulsion, if perfect, forms a cream which thick- 
 ens upon cooling and should adhere without oiliness to the surface of 
 glass. Used for spraying plum trees in spring and fall, also applied 
 to affected hop plants by means of a force pump and spray nozzle. 
 
 618. HOP PLANT-LOUSE. 
 
 Phorodon humuli. 
 
 Eemedy: Quassia. A decoction of quassia chips, made by steeping 
 them in water, is recommended as a wash for the Hop Louse and gives 
 fairly good satisfaction, but is less serviceable than the kerosene emul- 
 sion. 
 
 619. CHINCH BUG. 
 
 Blissus leucopterus. 
 The Eggs. 
 
 The greatly enlarged papier inache model represents the form of the 
 egg and the terminal cap. The eggs are three-tenths of an inch long, 
 the top being squarely docked and surmounted by four round tubercles 
 near the center. Color from pale whitish to amber. (See No. 272.) 
 
 620. CHINCH BUG. 
 
 Blissus leucopterus. 
 First larval stage. 
 
 This stage, represented greatly enlarged in the model, differs from 
 the adult in being more elongate and in having two-jointed tarsi, the 
 
76 
 
 head broader and more rounded and the joints of the body subeipial. 
 The prevailing color of the whole body is red. 
 
 621. CHINCH BUG-. 
 
 Blissus leucopterus. 
 Second larval stage. 
 
 After the first moult the form represented in the enlarged model is 
 assumed. The red becomes a bright vermilion and contrasts with the 
 pale band across the middle of the body, while the head and prothorax 
 are dusky and coriaceous. Two broad marks appear on the meso- 
 thorax and the second, fourth, and fifth abdominal sutures, and one at 
 the tip of the abdomen. 
 
 622. CHINCH BUG. 
 
 Blissus leucopterus. 
 Pupa. 
 
 The pupa shown in the greatly enlarged models approaches still 
 more nearly the form of the adult, and is not unlike the last larval 
 stage except in being darker and in the appearance of wing-pads, 
 which extend almost across the pale basal abdominal joints. 
 
 623. CHINCH BUG. 
 
 Blissus leucopterus. 
 The imago. 
 
 The mature insect, which is represented greatly enlarged in papier 
 mache, is elongate, blackish, and with numerous hairs, or pubescent. 
 Its length is about three-twentieths of an inch. The outer wings are 
 whitish, with a strong distinctive black spot. 
 
 624. FLUTED SCALE.

 COLLECTIHG INSECTS. 
 
 The important apparatus for the collection of insects consists of va. 
 rious styles of nets adapted for different methods of collecting. These 
 are for collecting insects during flight or about flowers, conrprising 
 butterfly nets ; for collecting insects from grass or shrubbery, or even 
 trees, comprising beating nets; and nets for collecting aquatic insects, 
 comprising water and dip nets. Several styles of nets for each of these 
 purposes are illustrated in the collection as follows: 
 
 Butterfly IVets. 
 
 The essentials of collecting apparatus of this class are a light ring 
 (preferably made so that it will fold into small compass for packing) 
 and a light, detachable handle, great strength of these parts or of the 
 net itself not being required on account of the fact that the net is used 
 chiefly in the air. The net is of cheese cloth or light muslin, and should 
 be made into a more or less pointed bag, having a length of about three 
 times the diameter of the net ring. 
 
 722. RILEY BUTTERFLY NET. 
 
 Made of two pieces of brass wire, each about 20 inches long, bent 
 half circularly and fastened at one end by a folding hinge, having a 
 check on one side. The other ends are beaten into two square loops, 
 which fit over a square projection on the end of the ferule and are 
 firmly secured by milled screw which fits into the end of the ferule. 
 This allows easy removal and folding into small space for convenient 
 carriage. 
 
 723. THE SCHONBORN BUTTERFLY NET. 
 
 This net is similar to the previous, but differs from it in the mode of 
 
 attachment of the ring to the ferule. The ferule is double and the 
 
 inner piece is deeply grooved on either side to receive the prolongation 
 
 of the wire forming the ring. The outer ferule, which is slid down on 
 
 the handle while the ring is being put in place, is then pushed up over 
 
 the inner ferule, firmly clamping the ring in place and forming a very 
 
 strong and satisfactory attachment. 
 
 89 
 
90 
 Sweeping' JVets. 
 
 A much heavier net is required for this purpose, to support the wear 
 coming from vigorous sweeping back and forth in shrubbery and grass. 
 The ring must be very heavy and provided with some means of pro- 
 tecting the cloth from wear at its point of attachment to the ring, and 
 the cloth or bag itself shculd be of much heavier material than in the 
 butterfly nets. 
 
 724. THE DEYROLLE SWEEPING NET. 
 
 The ring of this net is a strong flat piece of brass or steel, hinged 
 on either side to allow folding into small compass and grooved exte- 
 riorly, the groove being pierced by numerous small holes, so that the 
 net can be fastened on the inside and the fastening twine will be pro- 
 tected from wear by being sunk in the exterior groove. The net rim 
 has a square tongue which enters the ferule and is fastened in place 
 for use by means of a milled screw. 
 
 725. THE KIESENWETTER SWEEPING NET. 
 
 The principle of this net is in general the same as that of the Eiley 
 Butterfly Net, but the ring is of much heavier wire and the net proper 
 is attached to it by means of numerous small brass rings slipped on the 
 main ring of the net. These rings should not be more than three- 
 fourths of an inch apart, and the bag is sewed to them with strong 
 twine and thus protected from wear and tear. 
 
 726. THE FISH-NET RING. 
 
 A very satisfactory ring for a beating net is the smallest size of brass 
 folding net ring used for catching minnows. It is made of strong wire 
 and folds in two or three places into small compass and may be used 
 with or without rings, as in the last net described. 
 
 "Water Nets. 
 
 These nets are smaller than those just described and the net proper, 
 which maybe either of cloth or wire netting, is much shorter, not much 
 exceediug the diameter of the net ring. 
 
 727. THE PACKARD WATER NET. 
 
 The net ring in this apparatus is moderately strong and is bent 
 squarely across at the front edge to facilitate the scraping of logs or 
 submerged stones. The net proper is either of coarse grass cloth or 
 wire netting. 
 
 728. THE JOCKEY-CAP DIP NET. 
 
 This is a small water sieve or scoop and is made of wire netting and 
 tin. It is used to collect any particular specimens of aquatic insects or 
 to scrape submerged stones or timber. 
 
91 
 
 Collecting' by Beating. 
 
 Apparatus for this work consists of an umbrella, beating cloth or 
 other device, which is held beneath a limb or shrub and the latter jarred 
 by means of a stick or by shaking, thus causing the insects to fall from 
 it upon the collecting surface beneath, where they are captured. 
 
 729. THE UMBRELLA. 
 
 A common umbrella may be used for this purpose, or one specially 
 constructed with a joint near the middle of the handle to facilitate its 
 being held beneath branches and to allow of its being packed into 
 small compass. 
 
 730. THE BEATING-CLOTH. 
 
 This is used as a substitute for the umbrella, and consists of a stout 
 cloth, a yard square, with a loop of strong twine sewed in at each cor- 
 ner. Two straight sticks to hold it expanded are placed crosswise and 
 fastened to the loops, by which means the cloth is kept outspread. 
 When not in use it can be folded up into small compass. 
 
 731. THE MARX UMBRELLA NET. 
 
 This net is made from an old umbrella, and two steel rods rttached 
 to an umbrella handle at the top and to a sliding ferule at the bottom, 
 constitute the ring. The net is a shallow bag of cloth. When in use 
 the ferule is slipped up the umbrella handle until it catches behind a 
 lip, forming a circle, and when not in use it is allowed to slide back 
 and resume the shape and size, with the net wound about it, of an 
 ordinary unbrella. It is used in beating, and also serves for sweeping. 
 
 732. THE SIEVE. 
 
 This is a most useful apparatus, and is employed for collecting in- 
 sects which are harbored by grass, leaves, or rubbish. The ordinary 
 sieve will answer the purpose, or one specially constructed as in the 
 example exhibited. It is used over a cloth or paper. 
 
 733. THE BAG SIEVE. 
 
 Two brass or steel rings, one of which is covered with wire ganze, 
 are attached to the top and bottom of a strong cloth bag 12 or 15 inches 
 long. Leaves or rubbish are placed in the bag, which is then shaken 
 over a collecting cloth, as with the ordinary sieve. 
 
 734. THE HAVERSACK. 
 
 The ordinary willow bag or basket used by anglers will serve the ento- 
 mologist to transport the various collecting bottles and apparatus 
 which it is necessary to take on excursions. Such a one is exhibited. 
 
92 
 Tweezers and Forceps, 
 
 A variety of implements for collecting - , pinning, mounting, and hand- 
 ling insects is essential to satisfactory work. These include tweezers 
 for collecting small and delicate specimens and transferring them to 
 bottles and vials; and various pinning and transferring forceps and 
 brushes. 
 
 735. PINNING FORCEPS FOR LETIDOPTERA. 
 
 These are peculiar, in being stronger and in having more or less de- 
 cidedly kneed handles, to adapt them for the heavier work of transfer- 
 ring and setting the larger Lepidoptera. The knee in the handle allows 
 the forceps to be thrust beneath the insect, and allows the pin to be 
 more securely thrust into the cork. 
 
 736. COMMON PINNING FORCEPS. 
 
 .The form exhibited is the one usually employed by entomologists, 
 and serves for all ordinary operations of pinning. Other styles, prac- 
 tically of the same character, are also shown. 
 
 737. COLLECTING TWEEZERS. 
 
 For this purpose any light, pliable, fine-pointed forceps are suitable, 
 the points being either straight or curved at the tip, according to indi- 
 vidual preference. They are used not only for picking up specimens 
 from the collecting cloth or umbrella, but are indispensable for extract- 
 ing insects from cracks or holes in timber, their burrows, etc. Of the 
 two or three styles exhibited, the larger can be used for collecting 
 scorpions or ferocious insects which one does not care to take with the 
 hand. 
 
 738 THE COLLECTING BRUSH. 
 
 A common camel's-hair brush is shown, which, being first slightly 
 moistened, is used for collecting very delicate specimens or in trans- 
 ferring them, to avoid the injury which would certainly result from 
 handling them with tweezers or the fingers. 
 
 739. THE COLLECTING PILL BOX. 
 
 This is a device for collecting Micro-Lepidoptera used by Lord 
 Walsingham. It consists of an ordinary pill box, the bottom of which 
 has been removed and a piece of glass substituted. This pill box ad- 
 mits of the immediate examination of specimens, so that worthless or 
 common species can be discarded. 
 
 Boxes for First Preservation of Living Specimens. 
 
 In collecting insects it is frequently necessary to keep the specimens 
 obtained alive for purposes of future study or for breeding, and a 
 
93 
 
 variety of boxes will be required to accommodate the insects or their 
 early stages of different orders. These boxes should be nearly air- 
 tight to prevent drying, and this will not endanger the life of the cap- 
 tures, because insects require very little air. 
 
 740-743. SEIDLITZ-POWDER BOXES. 
 
 These can be obtained of druggists, or made, by any tinsmith, of 
 various sizes, the corners being carefully rounded to permit of the 
 proper bending of the sides. They can be left in the flat until ready 
 for use, and then bent into shape. Two or three convenient sizes are 
 illustrated. The circular tin box used by watchmakers is also excel- 
 lent. 
 
 744. COLLECTING AND PRESERVING SUBSTANCES. 
 
 Under this head the chief agents for collecting and preserving and 
 mounting insects are exhibited — alcohol, chloroform, ether, cyanide 
 of potassium, benzine, gasoline, naphtha, creosote, benzole, Wickers- 
 heimer's preserving fluid, Spalding's glue, shellac (solid), shellac (fluid), 
 naphthaline cones, naphthaline crystals, gum camphor, bisulphide of 
 carbon, mercury, carbolic acid. 
 
 Collecting- Bottles. 
 
 These consist of any wide-mouthed bottle, or specimen tubes may 
 be used, and they may be of a variety of sizes, to accommodate the dif- 
 ferent orders of insects. A number of styles are exhibited. Nearly 
 all the collecting bottles now used are charged with cyanide of potas- 
 sium, which is put in in the solid form and held in place on the bottom 
 of the vial by pouring in liquid plaster of Paris, which subsequently 
 hardens, or by fastening it down with a paper wad. 
 
 745. THE CYANIDE BOTTLE WITH PAPER STRIPS. 
 
 This is an ordinary cyanide bottle with plaster of Paris covering the 
 cyanide, but to prevent the insects from grating on each other and also 
 to absorb the moisture the vial above the cyanide is partially filled with 
 strips of bibulous paper. 
 
 746. THE CYANIDE BOTTLE WITH PAPER LINING. 
 
 The absorption of moisture, which is so injurious to delicate small 
 specimens, is also accomplished by putting a strip of blotting paper 
 around the inner side of the bottle and covering the plaster of Paris with 
 circular pieces of blotting paper just fitting the interior of the bottle. 
 
 747. VEST POCKET CYANIDE BOTTLE 
 
 This is made of a small test tube, the cyanide being broken up some- 
 what finely, and held in place by crowding in some soft and bibulous 
 paper. 
 
94 
 
 748. GOOSE-QUILL COLLECTING BOTTLE. 
 
 Tliis is made of a small cyanide bottle or test tube, and differs from 
 the foregoing in that a goose quill is introduced through the cork, so 
 that small specimens can be put into the bottle without first taking out 
 the cork. This form of bottle will last for several days, but will need 
 recharging oftener than other styles. 
 
 749. LARGE CYANIDE BOTTLE. 
 
 Similar to No. 745 or 746, but larger, and employed to kill the larger 
 moths, etc. 
 
 750. CHLOROFORM AND ETHER BOTTLES. 
 
 These are of especial value in the case of butterflies, moths, and del- 
 icate Hymenoptera and Diptera. An ordinary stout bottle, with a 
 camel's hair brush securely inserted in the cork, answers the purpose, 
 or in place of the brush a droppihg-needle may be inserted in the cork. 
 Both styles are shown. 
 
 Apparatus for Rearing' Insects. 
 
 A diversity of apparatus for the rearing of insects, indoors more 
 particularly, is used in the work of the Division of Entomology. A 
 considerable series of breeding-cages, jars, etc., is exhibited, showing 
 practically all the important vivaria needful for the securing of insects 
 and their protection during the study of their transformations and 
 habits. 
 
 751. LARGE GLASS BREEDING JAR WITH EARTH. 
 
 Illustrating method of breeding grass-feeding larvse in jar with 
 earth, in which the larvae may enter for pupation or hibernation. 
 
 752. PLOWER-POT BREEDING-CAGE. 
 
 This is a simple device for the rearing of insects on growing plants, 
 either indoors or out. It consists of an ordinary flower pot, containing 
 the plant which is to furnish food for the insect or which is already 
 effected, and a glass cylinder which fits closely into the top of the 
 pot, the free end being covered with muslin. Subject: Oak gall, from 
 New Mexico. 
 
 753. LARGE GLASS BREEDING JAR. 
 
 Containing maple leaves, and illustrating the method of breeding 
 Lepidopterous larva} which enter the soil to pupate. Subject: The 
 Maple Worm, Dryocampa rubicunda. 
 
 755. THE BREEDING CAGE OR VIVARIUM. 
 
 This, as at present improved, consists of three distinct parts — the 
 base, the box proper, and the top or cover. The base is specially con- 
 
95 
 
 structed to facilitate keeping the soil in the bottom of the cage moist 
 without pouring water in from above, which would cause packing. It 
 is of zinc, and so arranged that a pan surrounds the perforated com- 
 partment for the earth, thus allowing the water poured into the pan 
 to penetrate the perforations and moisten the earth in the breeding- 
 cage gradually and without the disadvantages alluded to. The box 
 proper or central portion has a swinging door, the other three sides 
 being of glass, or one or more of them may be covered with gauze to 
 give ventilation. The top is covered with wire gauze. This cage 
 admits abundant light and air, and is easily opened for the removal 
 of specimens, the insertion of fresh food, etc. 
 
 756. THE MUSLIN-COVERED BREEDING CAGE. 
 
 This apparatus is useful in the breeding and study of the habits of 
 insects affecting small grains and forage plants, and is applicable to 
 both indoor and outdoor experimentation. It consists of a strong box 
 for the reception of the earth in which the plants to be studied are 
 propagated, and of a light frame covered with gauze, which at the 
 proper time may be fitted closely over the growing plants to retain 
 the insects that have been introduced or to protect the plants from 
 undesirable species. The one exhibited is of small size, and larger 
 boxes will ordinarily be more convenient, while for field work the box 
 with the growing plant may be embedded in the soil, or the screen 
 alone may be used to cover a portion of naturally growing vegetation. 
 
 757. THE ROOT CAGE. 
 
 This apparatus was devised for the study of insects affecting the 
 roots of plants, and consists of a zinc frame with two plates of glass in 
 a vertical position, with an arrangement for a zinc sliding cover which 
 fits into grooves, and may be removed to admit of examination of the 
 progress of the root-infesting insects. The cage exhibited is of small 
 size, but in the work of the Entomologist cages of various sizes are 
 used, some being very large to admit of the reception of small shrubs. 
 
 758. PENT-HOUSE BREEDING CAGE. 
 
 This is exhibited to illustrate a simple method of constructing a cage 
 for the breeding of insects which feed on low plants, or for use in the 
 field on collecting excursions. It is constructed by cutting two flexi- 
 ble twigs and bending them into the shape of two arches, putting one 
 over the other at right angles and pushing the ends well into the 
 ground. Over the pent-house thus formed a piece of gauze is stretched 
 and the cage is complete. 
 
 759. THE AERIAL BREEDING CAGE, OR BAG. 
 
 A simple device for the outdoor rearing of species which oviposit on 
 trees and large shrubs is shown in this exhibit. It is valuable for 
 
96 
 
 the caging of female Lepicloptera out of doors, in order that they 
 may oviposit on a food-plant, or that the males may be attracted and 
 caught, either for introduction with the females or for the collection. 
 Tbe device consists in inclosing a branch of a tree in netting, care 
 being taken to avoid all creases or folds into which the insect might 
 crawl and be killed by spiders from the outside of the bag. 
 
 760-773. BREEDING JARS. 
 
 Much of the work of breeding insects can be most satisfactorily 
 accomplished by the use of ordinary candy jars or battery jars, or even 
 tumblers and test tubes of small size for very minute wood-boring or 
 gall-making insects. These may be covered with gauze, or, in the 
 case of nearly dry specimens, such as wood-boring insects, or galls, may 
 be inclosed with glass or cork stoppers, to prevent further evaporation 
 Tubes are also available for breeding delicate specimens, such as root 
 lice, or for inclosing the stems of plants containing internal feeders, 
 or for the reception of delicate pupa?. A large series of jars represent- 
 ing the various styles used is exhibited. 
 
 774. INSECT PINS. 
 
 In mounting insects for the cabinet expressly made entomological 
 pins are used. There are three principal kinds, the Klaeger, the Carls- 
 bad, and the Vienna pins. The Klaeger and Vienna pins are also 
 made japanned, for use with insects which are liable to verdigris. 
 For very minute Lepidoptera and Diptera, etc., very delicate pins are 
 used, such as the Vienna " Minutien nadeln." 
 
 775, 776. THE INSECT PUNCH FOR CUTTING TRIANGLES. 
 
 The mounting of insects on points, illustrated in this exhibit, neces- 
 sitates the cutting of cardboard points of various shapes to accommo- 
 date insects of different sizes, and greater accuracy and rapidity may 
 be secured by the use of a special punch similar to those used by con- 
 ductors. One of these is exhibited, also samples of three sizes of the 
 cut points. 
 
 777. PINNING AND MOUNTING INSECTS. 
 
 An exhibit is made illustrating the different methods of pinning in- 
 sects in the different orders, and of mounting or otherwise disposing 
 of insects for the general collection or for storage as duplicates. 
 
 Spreading' apparatus. 
 
 For the proper disposition of butterflies, moths, etc., for the cabinet 
 spreading boards are necessary. 
 
 778. SPREADING BOARD FOR LEPIDOPTERA. 
 
 The exhibit represents the form of spreading board commonly used. 
 It is made of soft white pine, with a strip of cork beneath, in which to 
 
97 
 
 pin the specimens. A slight slant from the middle upward must be 
 provided for in stretching boards in order to counteract the tendency 
 of the wings, however well dried, to drop after the insect is placed in 
 the cabinet. 
 
 779. SPREADING CASE. 
 
 This is designed for use where a good deal of work is- to be done. 
 Five or six spreading boards are made together, forming a shelf, and 
 a number of these shelves are arranged as slide drawers in a suitable 
 case, which is compact and prevents the specimens from being injured 
 by other insects while they are being dried. 
 
 780. DRYING- OVEN. 
 
 For the inflation of the larvae of Lepidoptera a tin drying oven, 
 placed over an alcohol lamp, is used. The sides are of glass or mica, 
 so that the larva is constantly in view, and the oven is furnished with 
 suitable sliding or hinged doors and with a brass screen on the lower 
 side to regulate and distribute the heat. 
 
 781. MICROSCOPIC SLIDE CASE. 
 
 This is made of strong pasteboard and is arranged to hold twenty- 
 six slides, the cover bearing numbers from 1 to 26, opposite which may 
 be written the name of each insect mounted and labeled on the re- 
 spective slides. 
 
 782. BALSAM SLIDE MOUNTS. 
 
 An exhibit is made of a number of slides showing the method fol- 
 lowed in the 'work of the entomologist in mounting and labeling 
 specimens. 
 
 The preservation of aleoliolie specimens. 
 
 Very much of the biologic material in entomology will be kept in 
 alcohol or other preservative fluids. There are a number of methods 
 of storing the vials, two of the most satisfactory being illustrated. 
 
 783. THE RILEY VIAL-HOLDER. 
 
 This consists of a small block of wood, in the upper side of which 
 are fastened two curved clamps of music wire, each forming about two- 
 thirds of a circle, and on the back are set four pointed nails which 
 project about one-fourth of an inch, and serve to hold the block to the 
 cork lining of the case or drawer. The advantages of these holders 
 are the ease with which the block can be removed for study or for re- 
 arrangement, and the facility of removing the vial itself from" the 
 holder. 
 
 23483— No. 31 7 
 
98 
 
 784, 785. THE MARX TRAY FOR ALCOHOLIC SPECIMENS. 
 
 In this methed tlie yials are stored in a wooden tray, the top piece 
 of which has a cork center in which holes corresponding to the size of 
 the vials are made with a punch. The trays are labeled on the outer 
 end, and numbers of them may be stored together on shallow shelves, 
 and the whole inclosed in a cabinet. Special vials are used, which 
 flare slightly at the top to prevent their sliding through the holes of 
 the upper part of the tray. 
 
 Insect boxes. 
 
 For the storage of insects both temporarily and in permanent collec- 
 tions a great variety of boxes are used, and also extensive cabinets or 
 drawers. Two styles used in the work of the Division of Entomology 
 are exhibited. 
 
 786. THE FOLDING INSECT BOX. 
 
 This box is of white pine, shellacked and varnished, the bottom and 
 top of double crossgrain to prevent warping, and lined inside with a 
 thin white-wood strip projecting above the rim of the outside of the 
 box, so that the lid in closing over this strip forms a very tight-fitting 
 cover and prevents the ingress of museum pests. The bottom is cork- 
 lined and covered with a fine white-glazed paper. The advantages of 
 this box are, that its position on the shelves can be readily changed, 
 and that it is convenient for handling. 
 
 787. THE CABINET INSECT-DRAWER. 
 
 This drawer is designed for the cabinets used in the Department of 
 Agriculture and the IT. S. National Museum for orders of insects 
 which have been pretty well worked over and put into permanent shape. 
 The construction of this drawer is somewhat complicated, as it is de- 
 signed to protect collections absolutely from museum pests. A prom- 
 inent feature is that the space between the outer and inner walls of 
 the box, between which the tongue of the cover fits, is charged with 
 some insecticide, such as napthaline, which insures the death of any 
 insect which may succeed in gaining a partial entrance to the drawer. 
 This drawer is employed in the insect displays of this exhibit. 
 
SECTION 5— INSECTICIDES. 
 
 ARSEIVITES. 
 
 These poisons are of the greatest service against mandibulate insects, 
 and on account of their caustic properties are of some use against soft- 
 bodied haustellate insects. Unless used cautiously on most plants they 
 are liable to seriously burn the foliage. They may be used dry, either 
 pure or diluted with 100 to 200 parts of flour or other diluent, but are 
 best mixed in water, one pound to 200 to 250 gallons and applied by 
 spraying. To prevent injury to foliage add lime water, milky but not 
 thick enough to clog the nozzle, at the rate of 2 gallons to 100 gallons 
 of spray. White arsenic should never be used without this precaution. 
 Fruit trees should not be sprayed with arsenites until after the blossoms 
 have fallen, on account of the danger of poisoning bees. 
 
 788. WHITE ARSENIC. 
 
 Commercial white arsenic pounds . . 1 
 
 Lime do 2 
 
 Boil together in 2 to 5 gallons water for half hour. Dilute with 150 
 to 250 gallons of water. 
 
 789. ARSENIC MASH. 
 
 Arsenic parts.. 1 
 
 Sugar do... 1 
 
 Bran do. .. 6 
 
 Thoroughly mix bran and arsenic. Dissolve sugar in water, add it 
 to the bran and arsenic, and mix thoroughly, adding water until the 
 whole mass is saturated. Placed about plants to protect from locusts, 
 
 790. ARSENIATE OF SODA. 
 Not commonly used. 
 
 791. LONDON PURPLE. 
 
 Same as Paris green. 
 
 792. PARIS GREEN. 
 
 Used dry, diluted or undiluted. As a spray, use 1 pound to 200 or 
 250 gallons of water, with addition of limewater as above. 
 
 99 
 
100 
 
 793. PARIS GREEN— Adulterated. 
 
 Is often sold by the trade. Can be detected by use of strong am- 
 monia, which completely dissolves pure Paris green, leaving no sedi- 
 ment. 
 
 794. PARIS PURPLE. 
 
 Used like Paris green. 
 
 OTHER INSECTICIDES. 
 
 795. ACETIC ACID. 
 
 In dilution to about 10 to 15 per cent of the acid. It is applied as a 
 spray. 
 
 796. CARBOLIC ACID. 
 
 A solution of 1 part in 100 of water is used against parasites on do- 
 mestic animals and in their houses. Mixed with soft soap and lime it 
 is applied, in spring, to tree trunks to repel borers. It may also be 
 used in solution or in emulsions, either on the foliage or among roots 
 of plants, but kerosene is preferable. 
 
 797. SALICYLIC ACID. 
 
 Is applied in powder or solution to soft-bodied insects. 
 
 798. SULPHURIC ACID. 
 
 A weak solution is sprayed on soft-bodied insects. 
 
 799. COTTON-SEED OIL. 
 
 Rubbed on domestic animals against parasites. 
 
 800. OIL OF TURPENTINE. 
 
 Applied on the bark of trees and on live-stock suffering from para- 
 sites. Is also emulsified with soapsuds and used as a spray against 
 soft-bodied insects. 
 
 801. FISH OIL. 
 
 Is used pure or with the addition of a little carbolic acid on domestic 
 animals to repel insect pests. (See also fish-oil soap.) 
 
 802. PETROLEUM— Crude. 
 
 803. PETROLEUM— Refined. 
 
 If broken into a very fine mist, may be sprayed sparingly on dor- 
 mant trees and shrubs and on very hardy foliage. The various emul- 
 sions are much preferable for most purposes. 
 
101 
 
 804. KEROSENE— Whale-Oil Soap Emulsion. 
 
 In 1 gallon boiling hot water half pound of whale-oil soap is dis- 
 solved. To this is added 2 gallons of kerosene and the whole is churned 
 vigorously with force-pump and spray nozzle until a creamy emulsion 
 results which will adhere without oiliness to glass. In regions in 
 which the water is strongly impregnated with lime or magnesium, rain 
 water or water previously broken with lye should be used. 
 
 805. KEROSENE MILK EMULSION. 
 
 To one part sour milk add two parts kerosene and churn by a force 
 pump or other agitator. A butter-like emulsion results in from three 
 to five minutes, and is diluted ad libitum with water. For fuller par- 
 ticulars see late reports and bulletins of the Entomologist. 
 
 806. KEROSENE— Bar-Soap Emulsion. 
 
 Same as above, except common bar soap is used in place of whale-oil 
 soap. 
 
 807. GASOLINE. 
 Used on domestic animals against insect pests. 
 
 808. BENZINE. 
 
 This is used in cabinets or applied to household goods to destroy 
 vermin. Enough is applied to make its odor as strong as possible. 
 
 809. TRAIN OIL. 
 Is used the same as fish oil. 
 
 810. CREOSOTE. 
 
 Used like carbolic acid. 
 
 811. SOAP— Soft. 
 
 This is rubbed on the trunks of trees to protect from, or to kill, in- 
 sects. As a strong suds may also be used as a spray. 
 
 812. SOAP— Common Bar. 
 
 Used the same as soft soap, and as suds. 
 
 813. SOAP— WHALE OIL. 
 
 Used the same as soft soap, but better. 
 
 814. FISH-OIL SOAP. 
 
 Is used in solution against plant lice. 
 
 Hirsch's crystal potash lye pounds . . 1 
 
 Fish oil pints.. 3 
 
 Soft water gallons.. 3 
 
 Dissolve the lye in the water, bring to a boil, add the oil, continue 
 the boiling two hours. For use dissolve 1 pound of the soap in o^to 10 
 gallons of water and apply as a spray. 
 
102 
 
 815. CARBOLIC SOAP. 
 
 Any of the above soaps impregnated with carbolic acid. Used on 
 domestic animals against parasites. 
 
 816. RESIN SOAP. 
 
 Is used against scale insects and plant lice, but is scarcely equal to 
 kerosene emulsion. 
 
 Caustic soda pounds.. 1 
 
 Kesin do 2 
 
 Tallow do.... 1 
 
 Dissolve the caustic soda in 1£ gallons water. In this dissolve the 
 resin and tallow with moderate heat, adding water to make 22 pints of 
 brown thick soap. For use dilute with 44 gallons water and apply as 
 a spray. 
 
 817. RESIN COMPOUND FOR SUBTERRANEAN INSECTS. 
 
 This remedy is valuable against Grape phylloxera, Apple Eoot-louse, 
 and other underground insects, having given excellent results with the 
 first two species named. It is made by combining 5 pounds of caustic 
 soda with 40 pounds of resin and diluting with water to 50 gallons. 
 Dissolve the soda in a small quantity of water by boiling and add the 
 resin. After the whole is dissolved, boiling water is added slowly to 
 make 50 gallons of the compound. For use, dilute to 500 gallons and 
 apply, in the case of the Phylloxera, 5 gallons to each vine, pouring it 
 into a basin excavated about the stock of the plant. 
 
 818. RESIN WASHES THE FORMULA FOR RED SCALE. 
 
 This insecticide has been employed with great efficiency in California 
 against the very injurious Bed Scale. It is made as follows : 
 
 Resin pounds.. 18 
 
 Caustic soda do 5 
 
 Fish oil pints.. 2± 
 
 Water, to make gallons.. 100 
 
 The three first named ingredients are placed in cold water and brought 
 to a boil, the temperature being maintained for about an hour and water 
 being added from time to time. The product will assimilate readily 
 with water and should be diluted with the proper quantity of cold water. 
 It should be strained through fine wire sieve or muslin before being 
 sprayed. 
 
 819. RESIN WASHES : FORMULA FOR SAN JOSE SCALE. 
 
 This is a stronger wash and is only applied during the dormant period. 
 It is made in the same manner as the first-named wash, but the boiling 
 is continued twice as long. The ingredients are used in the following 
 proportions : 
 
 Resin pounds.. 30 
 
 Caustic soda do ... . 9 
 
 Fish oil pints.. 4£ 
 
 Water to make gallons.. 100 
 
103 
 
 820. ALCOHOL. 
 
 A 30 per cent solution is sprayed on soft-bodied insects. Of but lit- 
 tle use. 
 
 821. ALUM. 
 
 Used either as a powder or in solution. 
 
 822. ASHES. 
 
 Wood ashes sifted on or placed around the bases of plants. 
 
 823. COAL ASHES. 
 Dusted on plants or placed about their base as a repellant. 
 
 824. BICROMATE OF POTASH. 
 Is dusted on leaf-eating insects. 
 
 825. BISULPHIDE OF CARBON. 
 
 For use in the ground, a quantity is poured or injected among roots 
 that are being injured. It is similarly used to destroy nests of ants. 
 Against insects injuring stored grain about 1£ pounds are used for each 
 ton of grain in a closed bin. It must be used cautiously, as the fumes 
 mixed with air are very explosive. 
 
 826. BORAX. 
 
 The powder or a strong solution is applied in crevices or on surfaces 
 frequented by roaches, etc., to drive them away. 
 
 827. BORDEAUX MIXTURE. 
 
 This important fungicide has some value as an insecticide. It is also 
 better than water as a medium in which to apply Paris green, the lime 
 preventing all injury to foliage. 
 
 Copper sulphate pounds . . 6 
 
 Lime - do 4 
 
 Water gallons . . 45 
 
 Dissolve the copper sulphate in 8 or 10 gallons of water, slack the 
 lime, add water enough to make a creamy whitewash; pour this slowly 
 through a coarse sack into the copper sulphate solution. Add water 
 to make 45 gallons. Add 4 ounces Paris green to eacli 50 gallons. 
 
 828. BRAN. 
 
 Often recommended for Cabbage Worm. Probably of little value. 
 
 829. CAMPHOR. 
 
 As a preventive this is confined in drawers and packages to pro- 
 tect dry goods and specimens. 
 
104 
 
 830. CARBOLIZED LIME. 
 
 Finely-pulverized fresh lime, 50 pounds. Crude carbolic acid, li 
 pints. Thoroughly mixed and dusted on plants as a repellant. 
 
 831. CARBOLIZED PLASTER. 
 
 Same as above, except that common land plaster (gypsum) is used in 
 place of the lime. 
 
 832. CHARCOAL. 
 
 Powdered charcoal is applied about the base of plants or dusted on 
 the foliage. 
 
 833. CHLOROFORM. 
 
 Used in closed cases against household pests and insects infesting 
 stored grains; also on domestic animals against certain pests. 
 
 834. COAL TAR. 
 
 Painted on tree trunks, etc., to catch or prevent insects from mount- 
 ing. By adding a few quarts to a barrel of water a solution is made to 
 sprinkle plants as a preventive. The smoke from burning coal tar is 
 used as a repellent. Emulsified with soapsuds it is applied as a spray, 
 using one-third coal tar to two-thirds soapsuds, and diluting with 5 to 10 
 parts of water. 
 
 835. CORROSIVE SUBLIMATE.— Mercuric chloride. 
 Chiefly used in solution against household pests. 
 836. CYANIDE OF POTASSIUM. 
 
 Chiefly used in fumigating fruit trees infested with scale insects. 
 For directions see publications of Division of Entomology. 
 
 837. DUST. 
 
 Fine dust is effective against various slugs — larvre of saw-flies. 
 
 838. GAS LIME. 
 
 Is applied to the soil to prevent injury to plants by root-feeding in- 
 sects. 
 
 839. GAS TAR. 
 
 A strong solution is sprayed on plants or applied about the roots. 
 Of but little value. 
 
 840. HELLEBORE. 
 
 The powder is sifted on alone or mixed 1 part to 20 of flour. With 
 1 gallon of water one-fourth pound is mixed, as a liquid to be sprayed. 
 
105 
 
 841. LIME. 
 
 The dry lime is sifted on, or, as whitewash, is applied with brush. 
 
 842. LYE. 
 
 Iii 1 gallon water 1 pound of concentrated lye is dissolved as a solu- 
 tion to spray on trees. 
 
 843. MERCURY.
