ish Beneath light fuscous with margins of pleurae, acet-

Were it not for generic differences this might be con- 
sidered as the female of Acroleucus maurus as the colora- 
tion is of a similar pattern, the strong ochreous and 
ferruginous markings here being obsolete or obscured in 
maurus. The membrane, however, is subhyaline with 
fuscous veins. Observations on the possible relationship 
of the two forms are desirable.
