Fore wing: male with a costal fold; cell more than two thirds length of fore wing ; upper discocellular minute ; middle and lower discocellulars inwardly oblique, the middle the longer ; vein 9 equidistant from 8 and 10 ; vein 2 from near base of wing; vein 3 about four times as far from 2 as from 4; vein 5 nearer 6 than 4. Hind wing produced into a short tail; vein 5 wanting; discocellulars barely traceable ; vein 3 from just before end of cell; vein 2 rather nearer to 3 than to base of wing. dorus, Edwards 1. Habitat. The Mexican subregion. 5. Genus TARSOCTENUS, nov. (Plates I. fig. 6 ; II. fig. 13.) Type, plutiu, Hewitson. Allied to Phocides. Antennse : club moderate, with a slender terminal hook. Palpi: second joint densely scaled; third joint naked, more prominent than in Phocides. Fore wing : male with costal fold ; cell considerably more than two-thirds length of costa ; discocellulars slightly oblique, middle slightly longer than lower; upper discocellular very short; vein 3 about half as far again from 2 as from 4; vein 2 nearer to base of wing than to vein 3. Hind wing with a distinct lobe at end of vein 1 b ; vein 7 well before end of cell; discocellulars very faint, slightly outwardly oblique; vein 5 barely traceable; vein 3 rather nearer to end of cell than to vein 2 ; vein 2 almost equidistant from base of wing and from end of cell. Hind tibise in both sexes very short, with only a terminal pair of spurs. In the male one of these spurs is much produced, and the proximal end of the tarsus bears beneath on either side a comb of yellowish bristles which, when the tarsus is straightened out, enclose the lengthened spur. This character is less developed in papias than in the other species of the genus. * plutia, Hew 1. corytas, Cram 2. pyramus, Cram. * proscia, Hew 3. * papias, Hew 4. One species, gaudialis, Hew., also belongs to this genus, but it is not in the British Museum. Confined to tropical America. 6. Genus PHOCIDES. (Plates I. fig. 5 ; III. fig. 2.)
