And one unidentified species. A very heterogeneous collection of species have been described as belonging to this genus, most of which belong to the genera Kerana, Sancus, Koruthaialos, Iambrix, and Baracus. Of the remainder, aryenteo-ornatus, Hew., eroites, Hew., and cynone, Hew., belong to Hesperilla or a closely allied genus; dhanada, Moore, aurivittata, Moore, and ladana, Butler, belong to Celcenorrhinus; while ornatus, Brem., and unicolor, Brem., belong to Heteropterus. Confined to Southern Asia. 40. Genus KERANA. Kerana, Dist. Rhop. Mai. p. 402 (1886). Type, armatus, Druce. Antennae long; club moderate, recurved at tip. Palpi: second joint densely scaled ; third joint almost entirely concealed. Fore wing : inner margin longer than outer; cell less than two-thirds the length of costa; vein 12 reaching costa before end of cell; middle discocellular quite twice the length of lower one ; vein 5 from close to bottom of cell; veiu 3 well before end of cell; vein 2 almost equidistant from vein 3 and base of wing. Hind wing : outer margin evenly rounded ; vein 7 shortly before end of cell; discocellulars and vein 5 faint, but not fully developed ; vein 5 nearer to 4 than to 6 ; vein 3 well before end of cell, nearer to 4 than to 2 ; vein 2 nearer to end of cell than to base of wing. Hind tibiae clothed with short recumbent scales and with two pairs of spurs. The male of the type species differs from the other species of the genus in being provided with a patch of appressed scales occupying the entire cell of the bind wing on the upperside, and giving it a velvety appearance, and with a similar ill-defined patch towards the base of the hind wing on the underside. A somewhat similar male character is found in the genus Trichosemeia, Holland. The other species of the genus are without secondary male characters. armatus, Druce 1. *gemmifer, Butler 2. diocles, Moore 3. The " Astictopterus " inornatus of Butler also apparently belongs to this genus, but the type is in too bad condition to enable the point to be decided. Confined to Southern Asia. 41. Genus RATREUS* nov. Type, johnstonii, Butler. Antennae very long; club slender, recurved, apex acuminate. Palpi as in Kerana. Fore wing: inner margin longer than outer margin; cell less than two-thirds the length of costa; vein 12 reaching 8* |
