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. caryae 
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 rounded. 
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. Scutellum 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, uniformly 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 rounded. 
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. a1g46.
