E. capysca Schaus. This species, and the following, so strikingly resemble Patreliura capys, that one  must look very closely in order to distinguish them; the principal distinguishing mark are of course the unpetioled upper median and lower radial veins of the hindwing and the rise of the upper radial of the forewing from the upper cell-corner. Besides, the base of the palpi is white, and the abdomen beneath spotted white, the whole animal being somewhat larger, at an average. The head is ochreous-yellow, spotted black, the forehead blackish with some white scales. The blackish-blue hindwings exhibit a hyaline spot in the cell, below and behind it.
Costa Rica (Tuis).


E. capyscoides Dogn. (20 b) is perhaps only a local race of the preceding, chiefly differing by the  presence of a white, diaphanous spot on the inner-marginal base of the hindwing; only the hindhead is orange.
The species described from French Guiana is before me also from Bolivia.
