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- 
tellum light reddish, sparsely setose apically; postscutellum reddish 
brown. Abdomen deep reddish orange, the segments posteriorly 
sparsely setose. Costa dark brown, subcosta uniting 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 curved, 
the pulvilli one-third the length of the claws. Ovipositor short, 
terminal lobes long, slender, narrowly rounded. Type Cecid. a1384.
