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 Musetmi 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 piuplish 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
