RESULTS OF THE YALE PERUVIAN EXPEDITION OF 1911.
HYMENOPTERA, SUPERFAMILIES VESPOIDEA AND
SPHECOIDEA.

By S. A. Rohwee,
Ofthe Bureau of Entomology, United States Department of Agriculture.

The Hymenoptera belonging to the superfamilies Vespoidea and
Sphecoidea obtained by the Yale Peruvian Expedition were col
lected in the following localities: Panama Canal Zone, Panama;
San Miguel, Peru; Santa Ana, Peru; Ollantaytambo, Peru; Arequipa,
Peru; Desert of Salavery, Peru; Cuzco, Peru. The following five
southeasternPeruvianlocalities, Paltaybamba, Tortontoy, Huadquina,
Tincochaca, and Pampaconas River can only be found in some of
the most recent atlases, but the Pampaconas River is a stream lying
between the Urubamba and Apurimac Rivers.
Of this lot of Hymenoptera referred to, consisting of 26 species, 14
are described as new, 11 are determined as heretofore described
species, and 1 which belongs to the genus Pepsis has not been deter-
mined. Nearly all of those species which were determined as having
been heretofore described belong to the family Vespictee, and most of
these have a wide distribution throughout the entire Neotropical
region. The insects belonging to the family Eumenidse are all
related to insects found in the high mountains of the Andes, and
more especially with the insects belonging to the Chilean fauna.
Insects of the superfamily Sphecoidea show no special affinities with
any region, in fact this may be said for many of them although a few
of the species have their allies either in insects belonging to the
Chilean fauna or insects which belong to the high mountain fauna of
Guatemala, etc. But few Hymenoptera have ever been described
from Peru and it is not surprising that more than half of those sub
mitted should turn out to be new species.
In the case of the two species of Mutillids described it may be
possible that they have been described by some of the older authors,
but no description could be found to apply well enough to miake their
determination certain. The two Mutillids are referred to the genus
Sphserophthdlma Blake where they run in Andre's synopsis of the
Proceedings U. S. National Museum, Vol. 44— No.- 1960. 4*jy

genera of Mutillidae, but according to the genotype of Sphserophihalma
these insects will have to be separated into a different genus, but until
it is possible to review the genera of the world they have been left
in Sphserophihalma so as to agree with the latest revision of these
insects. Superfamily VESPOIDEA.
Family PSAMMOCHARID^.
Genus PEPSIS Fatarieius.
A male collected at Huadquina, Peru, at an altitude of 5,000 feet,
July 25, 1911. This species may be described, although I can not
make it agree with any of the numerous descriptions, and as the genus
is in a chaotic state it is inadvisable to describe it at present.
Genus CRYPTOCHEILUS Panzer.
CRYPTOCHEH.US PEEUVIANUS, new species.
This species closely resembles fulvicornis, but may easily be sepa
rated by the lateral aspect of the propodeum being striate.

PSAMMOCHARES (PSAMMOCHARES) DICHROMORPHA, new species.
Readily distinguished by the bluish head and thorax and rufous
abdomen. Female. — -Length 12 mm. Stout. Anterior margin of the clypeus
very slightly incurved, the lateral angles rounded ; frontal impressed
line strong, complete; eyes slightly converging toward the vertex;
malar space nearly obsolete; ocelli in a low triangle; postocellar line
not quite twice the length of the intraocellar line; antennae of the

the post-basitarsis ; claws not strongly curved, with an erect median
tooth about the middle; transverse median vein of the fore wings
nearly its own length beyond the basal; third cubital cell on the
radius distinctly longer than the second on the same vein; first
transverse cubitus strongly curved, second cubital cell being much
narrowed above; third cubital cell receiving the second recurrent
vein distinctly before the middle; the third transverse cubitus
oblique so the third cubital cell is narrowed above; transverse
median of the hind wings slightly before the cubitus; abdomen
cylindrical, normal type; pygidium obtusely rounded apically;
apical ventral segments truncate; head and thorax black, at least
black in the places where the pubescence is wanting but very densely,

Cuzco, Peru. Described from one female collected July 4, 1911,
at an altitude of 11,500 feet.
Type.—C&t. No. 15108, U.S.N.M.
Genus ARACHNOPHROCTONUS Ashmead.
In Banks' generic synopsis for the North American Psammocharinae
the genus Arachnophroctonus is placed in the group which has erect
hair on the dorsal aspect of the propodeum. According to the type of
the genus and all the species in the collection of the United States
National Museum there is no erect hair on the dorsal aspect of the
propodeum, and the genus, according to Banks' arrangement, will

fall near Sericopompilus, from which it may be separated by hav
ing the hind tarsi spined, especially the apical joint beneath; the
propodeal spiracle opening posteriorly; the abdomen cylindri
cal, the first segment subequal in length with the second and not
narrowed anteriorly; the dorsal aspect of the propodeum with a me
dian impressed Une, more distinct basally; the posterior margin of
the pronotum with a longitudinal impressed median line; and the
species largely ferruginous. In some of the Neotropical species of the
genus Arachnophroctonus the dorsal lateral angles of the pronotum
are strongly tuberculate. This tuberculation is much stronger in
tuberculatus Smith. ARACHNOPHROCTONUS XANTKOPTERUS, new species.
This species is related to tuberculatus (Smith), but may easily be
separated by not having the wings banded with fuscous. Bubigino-
sus Taschenberg may belong to this genus, but the black on the
abdomen will readily separate xanthopterins from Taschenberg's
species. The yellow wings readily separate xanihopterus from the
Nearctic ferrugineus.
Female. — Length 14 mm. Clypeus gently convex, the anterior
margin nearly truncate; supraclypeal area flat; above and between
the bases of the antennae is a large rounded tubercule ; impressed line
line-like, complete; ocelli in a low triangle; postocellar line dis
tinctly longer than the ocellocular line; inner margins of the eyes
curved, closer together at the vertex than at the clypeus; malar
space short but present; antennae tapering apically, the third joint
nearly twice as long as the fourth ; posterior margin of the pronotum
broadly, arcuately emarginate, well developed laterally; metanotum
with rather long, dense, gray hair; dorsal, posterior lateral angles
of the propodeum strongly tuberculate; dorsal middle of the pro
podeum strongly convex; third cubital cell on the radius subequal
in length with the distance between the third transverse cubitus and
the costal margin of the radius; second recurrent vein received
about the middle of the third cubital cell, first recurrent vein received
about the apical fifth of the second cubital cell; transverse median
of the fore wings interstitial with the basal vein; transverse median
of the hind wings interstitial with the cubitus; legs rather strongly
spined, tarsal claws with an erect inner tooth, tarsal comb well de
fined; abdomen normal, the apical dorsal segment broadly rounded
apically. Ferruginous; four apical joints of the antennas, base of
the first abdominal segment, narrow apical margin of the first and
second tergites and most of the thoracic sutures black; wings strongly
yellowish, apices dusky; venation the color of the wings; dorsal
aspect of the thorax and the mesepisternum with very fine, ap
pressed golden pubescence; head with rather sparse, erect, golden
hair.

Genus CEROPALES Latreille.
CEROPALES BAS1RUFUS, new species.
This may easily be distinguished by the pale markings of the head
and thorax and by having the basal segment of the abdomen rufous.

tuberculate; pronotum, mesoscutum and scutellum with rather
large distinct punctures; scutellum convex; mesepisternum finely
granular; sides of the propodeum and the metapleurae finely granular;

finely granular with a V-shaped fovea at the base, a faint impressed
line from fovea to the ventral margin of the posterior face; legs very
feebly spined; third cubital cell on the radius strongly narrowed so
the distance between the second and third transverse cubiti is but
little greater than the distance between the second transverse cubitus
and the second recurrent vein; third cubital cell on the cubitus sub-
equal in length with the second; first transverse cubitus strongly
bent above the middle, second transverse cubitus straight; sec
ond recurrent vein in the basal third of the third cubital cell;

Genus PSEUDELAPHROPTERA Ashmead.
PSEUDELAPHROPTERA (?) MAURA, new species.
This species runs in Turner's table to the genera of Thynni^aa
to the genus Pseudelaphroptera Ashmead, but there are a number of
differences between this species and the genotype of the genus in
question, so it is doubtful whether it belongs to this genus. It may
when its female is known be a new genus. The following species is
asily separated from all other species of the genus Pseudelaphroptera
by its black color. Superficially it resembles closely Elaphroptera
atrata. Male. — Length 12 mm. Antennae, length 6 mm. Clypeus strongly

Genus CAMPSOMERIS Lepeletier.
CAMPSOMERIS (CAMPSOMERIS) SIMH.ARIS, new species.

same region, by the absence of black hair. This species resembles
the Nearctic fossulana but the abdomen lacks the bluish tinge,
the bands on the first and second tergites are broader and the prono
tum is yellow posteriorly. In Saussure and Sichel's Catalogue of the
species of this genus, this species seems to fall in Group 5, Division 3,
and is apparently closely to servillei Guerin but it does not agree
with the description of that insect.

Superfamily SPHECOIDEA.
Family SPHECID^E
Genus CALLOSPHEX Kohl.
CALLOSPHEX ERYTHROGASTRA, new species.
Superficially this species looks very like Palmodes rufiventris
(Cresson), but it differs from this widely in the structure of the clypeus.
This species is placed in the genus Callosphex because it runs there in

Ashmead's generic synopsis and because no important characters
are known to separate it from this genus. In Fernald's generic
table, using the first character as more important one, it would run
to Palmodes but will not agree with the description of Palmodes in
the character of the clypeus. Harpactopus edwardsi Cameron which
is described from this region has the tarsal claws with four teeth and
the second recurrent veins interstitial with the second transverse
cubitus, and there are other differences which will separate edwardsi
from eryihrogastra.
Female. — Length 12 mm. Inner margins of the eyes very slightly
converging toward the clypeus ; clypeus with apical margin depressed,
truncate except a narrow, shallow median notched; clypeus finely
granular except the median area which is shining with a few large,
scattered punctures; supraclypeal area triangular in outline, slightly
convex; head finely granular with a few scattered punctures;
median impressed line incomplete ; ocelli inclosed by a faint linelike
furrow; the postocellar line subequal with the ocellocular line; intra-
ocellar line about three-fourths the length of the postocellar line;
antennae filiform, third joint about one- third longer than the fourth;
mesoscutum granular laterally, the disk shiny, sparsely punctured;
scutellum shiny, sparsely punctured with a faint impressed, median
line; propodeum finely, closely granular; a linelike furrow sepa
rating off the dorsal aspect into a U-shaped area similar to that
found in the subfamily Sceliphroninae with the exception that this
area is not raised; anterior femora slightly swollen basally; tarsal
comb present but not uniform; tarsi normal, rather feebly spined;
claws with two inner teeth near the base; second cubital cell nar
rower on the cubitus; first recurrent vein nearly interstitial with
the first transverse cubitus, second recurrent vein received well into
the third cubital cell; petiole a little longer than the hind coxa;
abdomen shiny, the apical ventral segment subcompressed. Black;
abdomen from the petiole rufous; head and thorax clothed with long
black hair; the inner margins of the eyes below the antennae with
sparse appressed silvery pubescence; wings bluish, dusky apically;
venation dark brown.

Genus ISODONTIA Patton.
ISODONTIA BIPUNCTATA, new species.
This may be Sphex robusta Cameron, but judging from his descrip
tion it would seem that he had a specimen which was punctured like
azteca Fernald or macrocephala Fox. He says "vertex shining," in
the species here described the vertex is opaque. His specimen is
also said to have gray hair on the metapleurae, in bipunctata the hair
on the metapleurae is black.
Female. — Length 20 mm. Head slightly broader than the thorax,
opaque, very finely, closely punctured, the vertex with large, distinct
punctures interspread; frontal impressed line strong, complete, divid
ing at the anterior ocellus and extending to the slightly depressed
area latrad of each posterior ocellus; ocelli in a low triangle, the
distance between one of the lateral ones and the anterior one sub-
equal with the width of the anterior ocellus; supraclypeal area sharply
carinate; clypeus finely granular with a number of large punctures
laterally, the anterior margin depressed in the middle with two short,
obtuse, broad lobes which are separated from each other by an emar-
gination which in width, is equal to about half the width of the lobe;
mandibles very broad, stout, bidentate apically, the inner and outer
teeth subequal in length (see fig. 1); antennae slightly thickening
apically, the joints subnodose, third joint one-third longer than the
fourth, the fourth slightly shorter than the fifth; mesoscutum opaque,
finely, closely punctured with a number of larger punctures inter
spread; scutellum shiny, sparsely punctured; mesepisternum punc
tured like mesoscutum; dorsal aspect of the propodeum finely, trans
versely aciculate with many rather close, medium-sized punctures,
in appearance opaque; legs rather feebly spined; petiole about
twice the length of the posterior coxae; venation of the normal type.
Metallic blue-green; mandibles, anterior margin of the clypeus and
palpi rufous; legs, except the four posterior femora beneath which
are piceous, scutellum and pronotum black; antennae black, the basal
joints of the flagellum slightly piceous beneath; lower inner margins
of the eyes, superior posterior orbits, tubercules, prepectus, spot above
the intermediate coxa, spot above the posterior coxa, and the abdomen
with short, appressed silvery pubescence; face, clypeus, pronotum,
anterior part of the mesoscutum, mesepisternum, propodeum and
femora with black hair; the vertex of the posterior orbits with long
gray hair or a mixture of black and gray; posterior part of the meso
scutum with short gray hair; wings purplish, slightly paler apically;
venation dark brown.

Kohl's idea of azteca, judging from his descriptions and a letter to
Fernald,1 is the same as Fernald's if we add the variety cinerea to
Fernald's description, but as neither of these descriptions describes as
accurately as desired the dentation of the mandibles, and inasmuch
as we have names which will agree with
all the forms of the museum, it has been
considered best to leave azteca out of
the following table. Judging from the
original description of azteca which says
"cinerea-hirtus," the variety cinerea
Fernald will have to be considered as
the same as azteca, and the name mac-
rocephala will be used for azteca Fer
nald. According to Fernald these two
would well be considered the same, as
there seems, by the study of additional
material, to be a variation in the fig. 1.— Apices of mandibles in isodon-

Genus SPHEX Linnaeus.
SPHEX (SPHEX) PERUVIANUS, new species.
Apparently most closely allied to Sphex [Ammophila] volcanica
(Cameron), but lacks the pubescence and has the third antennal
joint not more than twice the length of the fourth and the propodeum
is obliquely striate.
Female. — Length 18 mm. Head broader than the thorax, opaque,
finely granular with a few widely separated, incompletely defined
punctures; frontal impressed line strong but not complete; ocelli in
a low triangle; intraocellar line about two- thirds the length of the
postocellar line; postocellar line shorter than either the ocellocular
or the ocelloccipital line; anterior margin of the clypeus truncate,
surface punctured like the head; supraclypeal area broad, flat;
antennae rather stout, filiform, third antennal joint subequal in
length with the fourth and fifth; pronotum sculptured like the head;
