Psyche 
[December 
(except in transverse bands) hyaline; tumid elevation 
large, with large brown spot. Wings longer than abdomen. 
Rostrum extending almost to end of rostral channel, the 
tip blackish. Legs testaceous. Nervures of elytra, carinae, 
hood and paranota with a few erect spines. 
Length, 3.51 mm. ; width, 2.10 mm. 
Holotype, female, and two paratypes, females, Santa Cat- 
alina Mts., Arizona, July 15, 1925, alt. 5000-6000 ft., col- 
lected on Vauquelinia calif ornica (Torr.) Sarg. by A. A. 
Nichol. This is a very pretty and elegantly marked species. 
It is perhaps most closely allied to C. elegans Drake, differ- 
ing in the larger tumid elevations, more constricted elytra 
and the different formed hood. The types are in the col- 
lection of the author. 
OVIPOSITION OF THE ICHNEUMONID ITOPLECTIS 
CONQUISITOR (SAY) IN A LARVA OF 
PYRAUSTA NUBILALIS HUBN. 
By Milton F. Crowell 
During the summer of 1932 I was fortunate enough to 
see a female of Itoplectis conquisitor (Say) parasitize a 
larva of the European corn borer, Pyrausta nubilalis Hubn. 
When first observed the female hymenopteron was run- 
ning up and down over the upper part of a corn stalk, per- 
haps a foot below the tassel. Closer examination revealed 
that she was paying attention to a short section of the stalk 
just above a hole opening into a tunnel of the corn borer. 
She approached the hole, felt around it with her antennae, 
then proceeded to explore with her antennae the stalk just 
above it. After a short time, during which she felt over 
most of the area of the stalk for perhaps three inches above 
the hole, she stopped and thrust her ovipositor vertically 
into the corn stalk. She remained motionless for an esti- 
mated time of fifteen to twenty seconds. She then withdrew 
her ovipositor and flew away. 
Cutting open the stalk I found a mature larva of Pyrausta 
nubilalis in the burrow, directly under the spot where Ito- 
plectis conquisitor had thrust her ovipositor into it.
