RESULTS OF THE YALE PERUVIAN EXPEDITION OF 1911.
HYMENOPTERA— ICHNEUMONOIDEA.

By H. L. Vieeeck,
Of the Bureau of Entomology, United States Department of Agriculture.

Of the three species of Ichneumonidse collected by the Yale Peru
vian Expedition, all of which proved to be new to science, one belongs
to Cylloceria Schiodte, a genus new to South America; another to
Trachysphyrus Haliday, a little-known South American genus;
while the third species belongs to Anisitsia Viereck, recently described
from North America, but well represented in both North and South
America. No other species of this superfamily were submitted for
determination. ANISITSIA TnTCOCHACffi, new species.
Type-locality. — Tincochaca, 7,000 feet, Peru.
Type.— Cat. No. 15116, U.S.NJM.
Female.— Length, 11.5 mm.; head, including antennae, palpi,
mandibles, and labrum, shining black or at least blackish, lateral
ocelli nearer to the eyes than to each other, but nearer to each other
than to the occipital carina; thorax finely, opaquely sculptured and
punctured, including the stigma, veins, wing base, tegulse, coxae,
and trochanters black or blackish, rest of legs mostly blackish red,
wings faintly tinged with black; propodeum black and opaquely
sculptured, mostly reticulated, with the basal and apical transverse
carinas more or less developed, as in some cryptini, the apical trans
verse carina produced into a blunt process on each side, petiole
black, postpetiole and rest of abdomen rather castaneous, exserted
portion of the ovipositor hardly as long as the apical truncature of
the abdomen.
Labeled, "Collected August 10, 1911."
CTCXOCERIA TINCOCHAOffi, new species.
Type-locality. — Tincochaca, 7,000 feet, Peru.
Type.— -Cat. No. 15117, U.S.N.M.
Male. — Length, 8 mm.; related to O. marginator Schiodte, from
which it differs chiefly in the straight, more distinctly marginated,

posteriorly converging sides of the scutel, in the median longitudi
nal carinas of the propodeum converging posteriorly, and in the
presence of two longitudinal carina? on the first dorsal abdominal
segment between the spiracles and the base of the segment.
Labeled, "Collected August 8, 1911."
Genus TRACHYSPHYRJQS Haliday.
as determined by the writer, this genus goes to Catticryptus Ash-
mead, as placed in Schmiedetnecht's table in Genera Insectorum.
The latter genus is, however, misplaced and belongs properly near
Melanocryptus Cameron in the same table. The notauli in Tra-
chysphyrus, as represented by the following species, extend as distinct
furrows to beyond the middle of the dorsulum.
TRACHYSPHYRUS CLEONIS, new species.
Type-locality. — Cuzco, 11,500 feet, Peru.
Type.— Cat. No. 15118, U.S.N.M.
Female. — Length, 12 mm.; head shining, as seen from in front
virtually as long as wide, face greenish with purplish reflections,
clypeus purplish, with a few punctures, cheeks purplish, with widely
separated punctures, mandibles black, with purplish and greenish
reflections, front and vertex greenish, with purplish reflections,
lateral ocelli virtually as near to the eyes as to each other, scape
apparently shorter than the first joint of the flagel, the latter a
little longer than the next joint, scape greenish- and purplish, pedi
cel and flagel blackish, with reddish-brown sutures, palpi blackish;
thorax shiny and mostly greenish, dorsulum highly polished and
punctured, purplish, pronotum striated, mesopleurae wrinkled,
tegulae with scattered punctures and purplish, wings dark blackish-
brown, with violaceous reflections, stigma and veins blackish, coxae
and trochanters mostly purplish, femora and tibiae reddish, tarsi
mostly blackish; propodeum greenish, wrinkled, and shining; abdo
men finely shagreened and purplish, exserted portion of the ovi
positor apparently two-thirds as long as the abdomen.
