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. 
.Male. Length 2.5 mm. Antennae one-half longer than the body, 
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 1rreg- 
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 
the third. Mesonotum dark brown, the submedian lines fuscous 
yellowish. Scutellum light fuscous yellowish, postscutellum and 
abdomen slightly darker, the latter with irregular, fuscous markings 
basally and pale orange distally, the segments margined posteriorly 
with short, fuscous setae. Wings; costa reddish brown. Halteres 
yellowish transparent, fuscous subapically. Legs mostly a uniform 
light brown; claws slender, strongly curved, the pulvilli shorter than 
the claws. 
Female. Length 1.75 mm. Antennae nearly as long as the body, 
sparsely haired, light brown; 14 segments, the fifth with a stem 
about one-fifth the length of the cylindric basal enlargement, which 
latter has a length three and one-half times its diameter; distal
