This fuscous yellowish midge was reared at Albany, N. Y., August 

 7, 1907 from tulip leaves bearing galls of T h e c o d i p 1 o s i s 

 1 i r i o d e n d r i O. S. and presumably infested l3y aphids upon 

 which the larvae of this species probably subsists.

 rather thickly haired, light brown; 14 segments, the fifth with stems 

 two and one-half and three and one-half times their diameters, 

 respectively ; terminal segment having the distal enlargement strongly 

 constricted near the middle, with a length fully four times its diameter 

 and a stout, fingerlike process apically. Palpi; first segment irreg- 

 ularly subcjuadrate, the second narrowly oval, with a length two 

 and one-half times its diameter, the third one-half longer than the 

 second, more slender, the fourth a little longer and more slender than 

 the third. Mesonotum dark brown, the submedian lines fuscous
