long, reaching to two-thirds the length of the wing from the base ; 

 upper disco-cellular nervule long, strongly outwardly oblique ; middle 

 disco-cellular slightly longer than the lower disco-cellular, straight, 

 inwardly oblique ; lower disco-cellular upright, slightly anteriorly con- 

 cave, posteriorly straight ; second median nervule arising close to the 

 lower end of the cell ; first median arising about four times as far from 

 the second as the second does from the third, arising much nearer to the 

 lower end of the cell than to the base of the wing ; suhmedian nervure 

 sinuous. Hind wing, narrow, much broader than long ; costa strongly 

 arched at base, thence slightly arched to apex ; apex rounded ; outer 

 margin distinctly excavated at the termination of the first median 

 nervule ; anal angle well rounded ; abdominal margin slightly convex ; 

 costal nervure very straight, slightly curved at the base only ; first 

 subcostal nervule arising rather close to the apex of the cell ; disco-cellular 

 nervules concave, outwardly oblique ; discoidal nervule wanting ; second 

 median nervule arising quite close to the lower end of the cell ; first 

 median arising much nearer the end of the cell than the base of the wing, 

 arising at about three-fifths of the length of the cell from the base ; 

 suhmedian and internal nervures straight. Antennae long, more than 

 half the length of the costa of the forewing, the club moderately stout, 

 curved at the tip, the end of the club ending in a sharp point. Palpi 

 erect; second joint broad, densely hairy; third joint long, naked, slender, 

 acuminate, reaching well above the vertex of the head. Legs very 

 long and slender ; foreleg, tibia with an epiphysis ; hindleg, tibia 

 with two pairs of spurs. Thokax small, weak. Abdomen, slender, 

 long, reaching quite to the outer margin of the hindwing. Female. 

 Differs from the male only in the wings being somewhat broader. 

 Type, " Hesperia " swerga, de Niceville. 



This genus comes into Capt. E. Y. Watson's subfamily Pamphilince, 

 Section A (vide Proc. Zool. Soc. Lond., 1893, p. 71), and is allied to 

 Suastus, Moore ; Acleros, Mabille ; Iambrix, Watson ; Koruthaialos, 

 Watson ; Oxy palpus, Watson ; and Teinorhinus, Watson, with all of 

 which it agrees in the form of the palpi. It differs, however, from these 

 genera in the shape of the wings, which are greatly lengthened, and the 

 discoidal cell of the forewing being extremely narrow. It is perhaps 

 nearest to Koruthaialos, from which it differs in neuration in that the 

 second median nervule of the forewing arises nearer to the end of the
