Show 1893.] ME. E. Y. WATSON ON THE HESPEEIIDJE. 57 inseparable in structure from nyctinerne, and the prehensores of both species are very similar. Butler's male type of nyctineme is a female, his female type being an unidentified species of the genus Camptopleura ; the true male of nyctineme does not differ appreciably in markings from the female, though it differs of course in the secondary sexual characters of the genus, and also slightly in shape of wings, as in other species of the genus. Confined to tropical America. 24. Genus EANTIS. (Plates I. fig. 10 ; II. fig. 14 ; III. fig. 17.) Eantis, Boisd. Spec. Gen. pi. 9 B (1836). Type, busiris, Cram. Antennse : club very slender, hardly thicker than shaft, evenly curved, terminating in a fine point. Palpi as in Anastrus. Fore wing : apex conspicuously falcate, outer margin very convex ; inner margin slightly longer than outer margin ; cell less than two-thirds the length of costa ; vein 12 reaching costa at about half its length, considerably before the end of cell; middle discocellular erect, lower discocellular inwardly oblique, the lower the longer; vein 3 well before end of cell, less than twice as far from vein 2 as from 4; vein 2 nearer to base of wing than to end of cell. Hind wing much produced in median area, giving a very square appearance to the wing; cell short; vein 7 shortly before the end of cell; discocellulars barely traceable ; vein 5 almost invisible; vein 3 shortly before the end of cell, slightly nearer to 4 than to 2; vein 2 nearer to end of cell than to base of wing. Hind tibise with two pairs of spurs, and in the male with a tuft of hairs attached near the proximal end. In the male of busiris there is also a tuft of short hairs on a black silky patch of closely appressed scales at the extreme base of the costal margin on upperside of hind wing, and a precisely similar patch on underside of fore wing at origin of vein 1. This sexual character is not found in any other species of the genus. f busiris, Cram 1.
