deemed expedient eventually to divide the Lycsenidse into a small number of genera 

 Eumceus will, in all probability, include Theorema. 



The neuration of the primaries is almost exactly that of E. debora, the cell being 

 somewhat wider, and the first subcostal branch being emitted nearer the base of the 

 wing ; there is a single marginal filament attached to the end of the first median 

 branch of the secondaries ; the front legs of the male are less strongly s pined beneath. 

 The bursa copulatrix of the female has two slender chitinous spines. 



Theorema is represented by the single species the distribution of which is given 

 below.

Hewitson described this species from a Colombian specimen, a male. We have since 

 obtained several examples of both sexes from various parts of Central America, and 

 the female has recently been described by Mr. Strecker, under the name of Theorema 

 titania. 



We notice some variation in the females as regards the white marking at the apex of 

 the primaries, which is very obvious in the specimen we have described from Nicaragua - r 

 in one from Guatemala it is wholly absent, whilst in the State of Panama we find both 

 forms. 



A male and a female from Chontales, Nicaragua, are figured. 



B. Anal angle of secondaries more or less projecting beyond the curve of the 



outer margin.
