NOTES ON SOME AMERICAN TINGITIDAE
(HEMIPTERA)
Ames, Iowa
The present paper is based almost entirely upon a small collection of American Tingitidse kindly loaned to the writer by Nathan Banks of the Museum of Comparative Zoology, Harvard University, Cambridge, Massachusetts. In addition to Corythucha decepta, described below as new, this collection is represented by Monanthia monotropidia Stal, Gamboa, Canal Zone, July 9, 1924, collected by Na- than Banks ; Teleonemia prolixa Stal, Barro Colorado, July 23, 1924, N. Banks; Teleonemia albomarginata Champion, Barro Colorado, Canal Zone, July 19, 1924, and Rio Frio, Mgd., Colombia, P. J. Darlington; Teleonemia sacchari Fabr., Bella Vista, Panama, July 7, 1924, N. Banks; Aca- lypta ovata Osborn and Drake; Smoky Mts., N. C.-Tenn., Newfound Gap, Elevation 5,000-5,200 ft., collected in moss by Nathan Banks; Aeanthocheila armigera Stal, Bella Vista, Canal Zone, July 7, 1924, N. Banks ; Gargaphia nigri- nervk Stal, Rio Frio, Colombia, May 15, P. J. Darlington; Corythaica planaris Stal, Red Tank, Canal Zone, N. Banks ; Corythucha padi Drake, Hood River, Oregon, Sept. 5, 1917, F. R. Cole; Corythucha obliqua Osborn and Drake, Carmel, Cal., June 22, 1918, C. L. Hubbs; Corythucha spinosa Duges. The writer is indebted to Mr. A. A. Nichol for the specimens of Corythucha sagillata, n. sp., from Arizona. Corythucha decepta, n. sp.
Moderately large, testaceous, the pronotum and a more or less distinct band near the base of the elytra brown. Hood long, much smaller and placed a little farther for-

ward on the pronotum than in either C. setosa Champ. or C. eriodictyonas Drake. Pronotum finely punctate, mod- erately swollen ; lateral carinse not strongly elevated, the areolse very small, terminating anteriorly just behind the tumid area. Antennae and legs as in C. setosa. Paranota large, rather closely reticulated, the lateral spines wanting except along anterior margin. Median carina very low, not distinctly arched, uniseriate, the areolse very small. Elytra broad, with lateral spines along the costal margin; tumid elevation very small, not very distinct. Costal area broad, widely reticulated, irregularly triseriate, with some of the nervelets near the base darker and forming an in- distinct band". Wings a little longer than abdomen. Areolas hyaline.
Length, 3.65 mm. ; width, 1.82 mm.
Holotype, male, and alloitype, female, San Miguel, Hi- dalgo, Mexico, collected by Dr. W. M. Mann, Museum Com- parative Zoology. Paratypes, 13 specimens, taken with the type. The smaller hood, unarmed, paranota and elytra, and much smaller tumid elevations of- elytra separate this species at once from C. setosa Champ., C. eriodictyonse Drake, C. pacifica Drake and C. sphseracese Drake. The
lateral carinse are formed as in C. setosa and not as in the other species mentioned above.
The hood is not abruptly
constricted and much more elevated than the median carina. Corythucha sagillatfa, n. sp.
Moderately large, whitish testaceous, conspicuously marked with brown and fuscous. Hood moderately large, strongly and abruptly constricted near the middle, very strongly compressed and narrowed in front; posterior por- tion mostly brown, inflated and elevated. Median carina about half as high as hood, arched, there biseriate and with a brown patch. Lateral carinse whitish, raised anteriorly, terminating a little behind the hood. Paranota with brown markings, rather closely reticulated. Antennae testaceous, clothed with a few extremely long bristly hairs, the apical segment pale brown.
Elytra moderately constricted, with the usual cross- bands; costal area somewhat irregularly triseriate, areolse

(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- alina Mts., Arizona, July 15, 1925, alt. 5000-6000 ft., col- lected on Vauquelima califormica (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.
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.
