This reddish orange species was reared May 25, 1907 from a small, 

 monothalamous, almost imperceptible enlargement on the smaller 

 twigs of Cornus paniculata taken at Albany, N. Y. The 

 female has fourteen antennal segments, the fifth with a stem about 

 one-third the length of the basal enlargement, which latter has a 

 length about three times its diameter. The ovipositor is short and 

 the terminal lobes long, slender, narrowly rounded and thickly 

 setose. 



Gall. A small, monothalamous, almost imperceptible enlargement 

 on the smaller twigs. Length 5 mm, diameter 2.5 mm. The branch 

 has a diameter of only 1.5 mm. The larva occurs in a rather large, 

 oval chamber. 



Larva. Length 2 mm, whitish yellow, moderately stout. Head 

 small, triangular; antennae short, stout, uniarticulate. Body with 

 the segmentation moderately distinct; skin nearly smooth; breast- 

 bone roundly bilobed, the shaft obsolescent; posterior extremity 

 broadly rounded, with conical, chitinous, sublateral pseudopods and 

 just anteriorly a submedian pair of spined tubercles; sublaterally a 

 pair of rather long, stout spines. 



Female. Length 2.5 mm. Antennae extending to the fifth 

 abdominal segment, sparsely haired, pale yellowish; fourteen seg- 

 ments, the fifth with a stem one-third the length of the cylindric 

 basal enlargement, which latter has a length three times its diameter; 

 terminal segment somewhat reduced, subconical. Palpi; first seg- 

 ment stout, subquadrate, the second more than twice the length of 

 the first, rather slender, the third about as long, a little stouter, 

 the fourth one-half longer than the third. Face light fuscous yel- 

 lowish. Mesonotum yellowish brown, the submedian lines lighter, 

 thickly setose, the posterior median area light reddish yellow. Scu- 

 tellimi light reddish, sparsely setose apicaUy; postscutelltmi reddish 

 brown. Abdomen deep reddish orange, the segments posteriorly 

 sparsely setose. Costa dark brown, subcosta tiniting with the 

 margin at the basal third, the third vein just beyond the apex. 

 Halteres yellowish transparent, light fuscous subapically. Coxae 

 and base of femora yellowish transparent, femora distally, tibiae 

 and tarsi dark brown, the second and third tarsal segments on the 

 posterior legs fuscous yellowish; claws long, slender, slightly ciu-ved, 

 the pul villi one- third the length of the claws. Ovipositor short, 

 terminal lobes long, slender, narrowly rounded. Type Cecid. ai384.
