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

 7, 1907 from tulip leaves bearing galls of Thecodiplosis 

 liriodendri O. S. and presumably infested by 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 subquadrate, 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
