Very probably the same as the foregoing species (q. v.). 286. G. BUCHHOLZI, Ploetz. 2 • Hesperia buchholzi, Ploetz, S. E. Z. vol. xl. p. 354 (1879), vol. xliii. p. 330 (1882). Gangara (?) basistriga, Holl. Ent, News, vol. v. p. 29, pi. i. fig. 12 (1894). F Hab. Aburi (Ploetz) ; Ogove (Holland). Strangely enough, none but females of this species have been found thus far. The type was a unique female in the collection made by Buchholz. There is another specimen in my collection, and another still in the hands of Mons. Mabille, to which he has affixed the M S . name '; robustus." CTENIDES, gen. nov. Antennae long, slender; club moderate, long, produced at the apical extremity to a long fine point, bent back at a right angle. Palpi: first joint short, second joint long, erect, reaching the tip of the vertex, both densely clothed with long hair; third joint minute, erect, and almost concealed by the hairy vestiture of the second joint. Primaries with the inner margin longer than the outer margin, or, in some species, subequal. Cell slightly less than two-thirds the length of the costa ; vein 12 of the primaries terminating before the end of the cell; vein 7 arising slightly before the end of the cell ; vein 5 much nearer 4 than 6 ; vein 3 near vein 4; vein 2 from about the middle of the lower margin of the cell. The secondaries with vein 5 obsolete, or very faintly visible; discocellulars faint, angulated, with the point of the angle turned toward the base; cell short. Legs armed with double sets of spurs on the hind tibiae. The species of this genus, which is a large one, may be arranged in four groups. The first is represented typically by C. dacela, Hew., in which the primaries of the male have a sexual curved stigma below the cell crossing veins 3 and 2, and a large oval patch of raised, glossy hairs upon the outer end of the cell of the secondaries, covering the origin of veins 2, 3, and 4, and extending beyond toward the outer margin. The second group is represented by species in which the large oval patch of raised scales on the secondaries is absent, or at most represented by a tuft of loose and not conspicuous hairs. The discal band of the primaries is present. This group is composed of species of which C. maracanda and C. leonora are typical. The third group is composed of species in which the sexual brand of the primaries in the male is absent, while the large oval patch of hairs in the secondaries remains. |
