a whitish reflection, of two kinds, long lanceolate and shorter, broader blunt-

Legs rather stout, pale testaceous, scales with a whitish reflection, the brown 

 bristles contrasting. Claw formula, 0.0-0.0-0.0. 



Length : Body about 4.5 mm. ; wing 4.5 mm. 



Tlie life history and habits are unknown. The single specimen was taken 

 flying in the daytime in woods.

Center Harbor, July 19, 1903 (H. G. Dyar). 



Mansonia ochropus is known only by one female specimen. This specimen 

 may possibly prove to be an abnormally colored specimen of Mansonia pertur- 

 hans Walker. The peculiar pale scaling with silky luster suggests an aberration, 

 but the entire absence of the characteristic markings of M. perturbans compels 

 us to retain the species as a valid one for the present.
