new Species. It is probable that this form is widely distributed and 

 has heretofore been confused with C. caryae.a name which has 

 apparently been very loosely applied in the past. 



Gall. Irregularly subglobular, 2 to 4 mm in diameter, depressed 

 and without the small nipple so frequently seen in C. c a r y a e 

 galls. The gall is sparsely clothed with a short, yellowish pubescence 

 and has thin walls. 



Larva. Length 3 mm, stout, whitish, the head small; antennae 

 short, stout; breastbone unidentate, the shaft somewhat thickened 

 anteriorly and tapering posteriorly. Skin coarsely shagreened, 

 posterior extremity broadly rounded. 



Male. Length 1.75 mm. Antennae nearly as long as the body, 

 sparsely haired, reddish yellow, a variable carmine apically; fourteen 

 subsessile, cylindric segments, the fifth with a length two and one- 

 half times its diameter, the circumfila stout, the loops short, rather 

 thick; terminal segment reduced, tapering, narrowly roimded. 

 Palpi; first segment short, incrassate, the second rectangular, with 

 a length four times its diameter, the third short, narrowly oval, the 

 fourth one-half longer than the third. Mesonotum fuscous yellowish, 

 the submedian lines sparsely haired. Scutelltmi reddish brown, 

 postscutellum fuscous yellowish. Abdomen deep reddish orange, 

 the segments sparsely margined posteriorly with fuscous setae; 

 genitalia fuscous yellowish. Wings hyaline, costa dark brown. 

 Halteres yellowish basally, fuscous apically. Coxae and legs a vari- 

 able fuscous yellowish, the tarsi somewhat darker; claws rather 

 stout, unifomily curved, the pulvilli nearly as long as the claws. 

 Genitalia; basal clasp segment short, stout; terminal clasp segment 

 rather short, slightly swollen; dorsal plate broad, narrowly emar- 

 ginate, the lobes broadly rounded; ventral plate broad, broadly and 

 roundly emarginate, the lobes broadly roimded. 



Female. Length 2.75 mm. Antennae extending to the third 

 abdominal segment, sparsely haired, whitish transparent, a variable 

 carmine apically; fourteen sessile segments, the fifth with a length 

 two and one-half times its diameter, circumfil near the basal half 

 and apically; terminal segment somewhat reduced, tapering. Palpi; 

 first segment stout, second narrowly oval, the third a little longer, 

 more slender, the fourth one-half longer than the third. Mesono- 

 tum yellowish brown, the submedian lines sparsely haired. Scu- 

 tellum fuscous yellowish, postscutellum lighter. Abdomen dark 

 reddish orange; terminal segment and ovipositor fuscous yellowish. 

 Halteres pale yellowish. Coxae and legs mostly fuscous yellowish; 

 claws rather stout, strongly curved, the pulvilli as long as the claws. 

 Ovipositor short, the terminal lobes protuberant, tapering, narrowly 

 rounded. Cecid. ai946.
