This species is widely distributed though not, as a rule, very 
abundant. It has been recorded from the vicinity of New York 
City, occurs here and there and is occasionally numerous in the 
neighborhood of Albany, N. Y., and has been recorded from Ontario 
by Mr Jarvis. The gall is a small, greenish, conical deformity fre- 
quently with a blood-red or purplish red coloring. Galls bearing 
this name in the Museum of Comparative Zoology are nearer the - 
midvein than the margin of the leaf, conical and with a very 
slender tip. 
Gall. Two to 3 mm in diameter, conical with a distinct nipple, 
greenish and variably tinged with purplish or blood red. 
Larva. The larva has been described by Osten Sacken as yellowish 
with a distinctly pointed, spear-shaped breastbone. 
Male. Length 2 mm. Antennae nearly as long as the body, 
sparsely haired, fuscous yellowish; fourteen sessile segments, the 
fifth with a length two and one-half times its diameter; circumfila
