 1908 Felt, E. P. N. Y. State Mus. Bui. 124, p. 332 



This specimen was reared at Albany, N. Y., from an elongate 

 fusiform swelling on the stems of swamp milkweed, A s c 1 e p i a s 

 incarnata, adults appearing June 20, 1907. 



Gall. This species was reared from an elongate 

 fusiform swelling on the stem of Asclepias 

 incarnata. It occurs invariably at the joint and 

 on that account presents a symmetrical appearance, 

 which at first sight appears normal. The galls usu- 

 ally contain two larvae, one on each side of the 

 septum of the joint. 



Larva. Length 2.5 mm, rather stout, pale orange. 

 Head small; antennae uniarticulate ; breastbone 

 linear, bidentate, with a small median tooth and 

 slightly expanded distally ; skin minutely shagreened ; 

 posterior extremity broadly rounded. 



Female. Length 1.25 mm. Antennae black, 

 basally fuscous yellowish; 24 segments, the fifth with 

 a length about three-fourths its diameter; terminal 

 segment slightly produced, obovate. Palpi; the first 

 segment short, rectangular, with a length about 

 one-half greater than the diameter, slightly dilated 

 apically, the second stout, narrowly oval, a little 

 longer than the first, the third one-half longer and Fi 

 more slender than the second, the fourth about as 

 long as the third, somewhat more dilated. Face 

 whitish. Mesonotum black, margined anteriorly 

 and laterally with silvery hairs. Abdomen dark 

 brown, the first* segment covered with yellowish 

 white scales, the second narrowly bordered pos- 

 teriorly with silvery white, the third and fourth more broadly mar- 

 gined with silvery white posteriorly, remaining segments with a 

 scattered row of silvery hairs along the posterior margin ; ovipositor 

 pale yellowish. Wings hyaline, costa dark brown, the white discal 

 spot almost at the basal third, the third vein uniting with the costa 

 a little beyond the basal third. Halteres whitish transparent, anterior 

 legs dark brown, the femora basally white or pale, the posterior with' 

 a dark brown band near the middle and silvery apically; tibiae dark, 

 nearly to the base, the apical third silvery, tarsi black; claws long,
