Show 1893.] ME. E, Y. WATSON ON THE HESPEEHDiE, 83 of cell and base of wing, slightly nearer to base of wing. Hind wing outer margin even; vein 7 shortly before end of cell; vein 3 from end of cell; vein 2 more than twice as far from base of wing as from end of cell. Hind tibise with two pairs of spurs. *ophiusa, Hew. The above diagnosis is taken from ophiusa, Hew., which Mabille includes in his genus Hypoleucis. Confined to Africa. 21. Genus ISOTEINON. Isoteinon, Felder, Wien. ent. Monat. vi. p. 30 (1862). Type, lamprospilus, Felder. Antennse: club moderate, elongated, terminal crook short, tip acuminate. Palpi: second joint densely clothed with short scales; third joint erect, reaching well above the vertex of the head, slender, obtusely conical. Fore wing : inner margin considerably longer than outer margin; cell less than two-thirds the length of costa; discocellulars erect; vein 5 slightly nearer to 4 than to 6 ; vein 3 close to end of cell; vein 2 about equidistant from end of cell and base of wing in the male, considerably nearer to base of wing in the female. Hind wing narrow ; vein 7 shortly before end of cell; discocellulars and vein 5 faint, but distinctly traceable ; vein 3 immediately before end of cell. Hind tibise sparsely clothed with hairs and with two pairs of spurs. No secondary sexual characters on the wings. ( lamprospilus, Feld. \ vitrea, Murray. Many Indian species have been put into this genus ; none of those, however, which I have been able to examine belong to it, the direction of the third joint of the palpi alone readily distinguishing them. This genus appears to be allied to Hyarotis, Moore. Habitat. China and Japan. 22. Genus ISMA. Isma, Distant, Rhop. Malay, p. 386 (1886). Type, obscura, Dist. Antennse : club slender, elongate, with a short terminal crook, tip acuminate. Palpi porrect; third joint slender, almost concealed, bluntly conical. Fore wing: inner margin longer than outer margin ; cell less than two-thirds the length of costa ; vein 12 reaching costa well before the end of cell; discocellulars suberect; vein 5 slightly nearer to 4 than to 6 ; vein 3 shortly before end of cell; vein 2 almost equidistant from vein 3 and base of wing. Hind wing : not at all elongated, outer margin even, inconspicuously excised as vein 2 ; vein 7 immediately before end of cell, very remote from base of wing ; discocellulars faint, strongly outwardly oblique ; vein 5 not traceable ; vein 3 close to end of cell; vein 2 more than twice as far from base of wing as from end of cell; lower 6* |
