102 Psyche [December
(except in transverse bands) hyaline; tumid elevation large, with large brown spot. Wings longer than abdomen. Rostrum extending almost to end of rostra1 channel, the tip blackish. Legs testaceous. Nervures of elytra, carinse, hood and paranoia with a few erect spines. Length, 3.51 mm.; width, 2.10 mm.
Holotype, female, and two paratypes, females, Santa Cat- aha Mts., Arizona, July 15, 1925, alt. 5000-6000 ft., col- lected on Vauquelmia californica (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 CONQUZSZTOR (SAY) IN A LARVA OF
PYRA USTA NUBILALZS HUBN,
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 antennas 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 Zto- plectis conquisitor had thrust her ovipositor into it. Puche 39:102 1?2). http //psyche enkliib 011/39/39.102 him1
