Primaries brown, concolorous with thorax ; inner margin at base yellow- 

 ish, like posterior part of thorax, this shade disappearing before middle. Apices 

 of both lobes somewhat darkened. Cleft preceded by a vague blackish spot, 

 or two with vague dashes extending basad. Spot in cell at two-fifths from 

 base and one before this near inner margin, both sometimes faint. Fringes 

 brownish gray with pale bases. At the apex of each lobe, within the deft and 

 along the inner margin they contain black scales, chiefly collected into tufts at 

 regular intervals, five of these are usually evident on the inner margin. Sec- 

 ondaries gray brown, fringes slightly paler, without dark scales but with a 

 few dark hairs at apices of first and second lobes. Expanse 13.5-16.5 mm. 



The male genitalia are very different from any other known to 

 us, but we are able to trace a few slight points of relationship with 

 those of ccn-inicolor. 



Distribution: China. India, E. Indies, Africa, etc. In North 

 America it ranges from N. J. to Fla. and west into Mo. and Tex. 

 according to specimens which we have seen. The type locality is 

 Dallas, Tex. Fla. May and Oct., N. J. in Sept., S. C. in June. 



For some time we had a series of this species labelled as a new 

 species of Marasmarcha, and had just begun to suspect that it was 

 Zeller's species when a note from Mr. Meyrick reached us announcing 

 that pumilio and his Marasmarcha liophancs were the same species. 

 Later on we received the unique type & from the Cambridge Museum, 

 thus establishing its identity beyond doubt. 



Meyrick writes of the species that "it is doubtless artificially 

 introduced into N. America, being of alien character, the larva prob- 

 ably feeding in the pods of a cultivated Leguminous plant, like its 

 allies." 



One of Miss Murtfeldt's types of O. ambrosiac proved to be this 

 species. It bears the same breeding label as the others, and we should 

 therefore assume that it was reared from Ambrosia artcmisiac folia. 

 This is not at all compatible with Meyrick's information regarding the 

 allied species, but of course neither possibility is proven fact.
