brown; wings hyaline; halteres pale yellowish, fuscous sub- 

 apically ; coxae and femora basally pale yellowish, the remainder 

 of the legs dark straw ; claws moderately stout, strongly curved, 

 unidentate; the pulvilli about one-half the length of the claws; 

 ovipositor short, the lobes broadly oval and clothed sparsely 

 with rather coarse hairs. 



Pupa. Length 1.5 mm. Rather stout, yellowish orange, 

 the antennal cases extending to the middle of the thorax; the 

 wing cases to the third abdominal segment and the leg cases 

 to the fourth and fifth abdominal segments ; posterior extremely 

 broadly rounded, with a median furrow, the abdominal seg- 

 ments dorsally each with a rather broad, transverse band of 

 scattering weak spines. 



Larva. Length 1.5 mm. Moderately stout, yellowish 

 orange (probably reddish orange in life) ; head short, mostly 

 retracted; the breastbone weakly developed, bilobed anteriorly, 

 the lobes rather broad, broadly rounded and roundly excavated 

 at the internal basal angles; the shaft weakly and irregularly 

 developed; the posterior extremity obsolescent; near the middle 

 of each segment there is a transverse row of moderately long, 

 tapering, setose processes; skin rather finely shagreened, pos- 

 terior extremely broadly rounded. 



Type Cecid. A3176, New York State Museum. 



The larvae, as noted by Prof. Wheeler, live under a web in 

 small groups. The pupae occur intermixed and can be distin- 

 guished from larvae only with difficulty. The midges doubtless 

 emerge directly from these shelters.
