Center Harbor, July 19, 1902 (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- 

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

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

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