Show 1893.] ME. E. Y. WATSON ON THE HESPEEIIDiE. 45 Fore wing: outer margin longer than inner margin; no costal fold in male: cell less than two-thirds the length of costa; vein 12 reaching costa shortly before the end of cell; discocellulars suberect; vein 5 nearer 6 than 4 ; veinlet from lower discocellular ; vein 3 well before end of cell, twice as far from 2 as from 4 ; vein 2 twice as far from end of cell as from base of wing. Hind wing much produced; vein 7 nearer to base of wing than to end of cell; discocellulars and vein 5 very faint; vein 3 immediately before end of cell ; vein 2 three times as far from base of wing as from end of cell. Hind tibise with two pairs of spurs. platan, Fabr. Confined to tropical America. The genus Garga of Mabille (' Le Naturaliste,' p. 216, 1889), described for the species olena, is apparently congeneric with cono-gnathus, and olena is probably identical with platon. 2. Genus ARTEUROTIA. Arteurotia, Butler & Druce, Cist. Ent. i. p. 112 (1872). Type, tractipennis, Butler, Druce. Antennse : club rather robust, hooked, terminal portion short, less than half the length of club. Palpi porrect, widely separated ; third joint obtusely conical. Fore wing : outer margin rather longer than inner margin ; inner margin convex in its outer half; cell of fore wing less than two-thirds the length of costa ; vein 12 reaching costa opposite end of cell; discocellulars suberect, the lower the longer; vein 3 shortly before end of cell, twice as far from 2 as from 4 ; vein 2 twice as far from end of cell as from base of wing. Hind wing elongate, outer margin straight; discocellulars distinct ; vein 5 barely traceable; vein 3 immediately before end of cell ; vein 2 hardly nearer to end of cell than to base of wing. Hind tibise with two pairs of spurs. The male is without a costal fold, but is provided with a large silky patch of appressed scales, occupying the apical half of the hind wing on the upperside. tractipennis, Butl., Druce. Confined to tropical America. 3. Genus SOPHISTA. Sophista, Plotz, Stett. ent. Zeit. xl. p. 176 (1879). Type, aristoteles, Westw. Antennas : club moderate, bent into a hook, terminal portion very slender, less than half the length of remainder of club. Palpi porrect, widely separated ; third joint obtusely conical. Fore win°- : inner and outer margins subequal; cell of fore wing less than two-thirds the length of costa; vein 12 reaching costa almost opposite the end of cell; discocellulars suberect, the lower the longer ; vein 3 shortly before the end of cell, more than twice as far from 2 as from 4 ; vein 2 more than twice as far from end of cell as from base of |
