116 MR. E. T. AVATSON ON THE HESPERIIDjE. [JaU. 17, 



costa before end of cell ; upper margin of cell sharply bent 

 downwards at vein 8 ; veins 7 and 6 well below the angle ; upper 

 discocellular considerably longer than lower ; vein 5 much nearer 

 4 than G, but not from close to bottom of cell ; vein 3 well before 

 end of cell, twice as far from 2 as from 4 ; vein 2 about equidistant 

 from vein 3 and base of wing. Hind wing evenly rounded ; vein 7 

 well before end of cell ; discocellulars and vein .5 faint ; vein 3 

 immediately before end of cell ; vein 2 considerably nearer to end of 

 cell than to base of wing. Hind tibise in the male only with terminal 

 spurs, the ventral surface thickly set with short spines ; the dorsal 

 surface with a long fringe aiid also along tuft of hairs attached near 

 tlie proximal end. 



*johnstonii, Butler. 



Allied to Kerana. 



Confined to Africa. 



42. Genus Ancistkoides. 



Ancistroides, Butler, Trans. Ent. Soc. 1874, p. 436. 



Type, lotifficornis, Butler. 



Antennae very long ; club slender, recurved, tip acuminate. Palpi 

 as in Keratia. Fore wing : inner margin longer than outer margin ; 

 cell less than two-thirds the length of costa : vein 12 reaching; costa 

 before end of cell ; middle discocellular quite twice as long as 

 lower one ; vein 5 from close to bottom of cell ; vein 3 shortly 

 before end of cell; vein 2 much nearer to base of wing than to vein 

 3. Hind wing evenly rounded; vein 7 shortly before end of cell ; 

 discocellnlars and vein .5 barely traceable ; vein 3 immediately before 

 end of cell, many times farther from 2 than from 4 ; vein 2 

 nearer to end of cell than to base of wing. Hind tibiae with two 

 pairs of spurs and slightly clothed with short recumbent scales. 



longicornis, Butler 1. 



*o//w?i/as, Hew 2. 



This genus is nearest allied to Kerana, but differs from it 

 markedly in the })osition of the median branches of both wings. 

 Longicornis is from Timor and othonias from Borneo. 



43. Genus Pirdana. 



Pirdana, Distant, Rhop. Mai. p. 376 (1886). 



Type, hyela, Hewitson. 



Antennae long ; club slender, tip recurved, acuminate. Palpi; 

 second joint densely scaled, third joint minute. Tore wing : iiuier 

 and outer margins subequal ; cell less tban two thirds the length of 

 costa : vein 1 2 reaching costa well before end of cell ; upper disco- 

 cellular minute, lower and middle discocellular inwardly oblique, the 

 middle one considerably the longer ; vein 3 very close to end of cell ; 

 veinlet in cell just beyond vein 3 ; vein 2 less than twice as far 

 from end of cell as from base of wing. Hind wing : outer margin 

 even, lobe inconspicuous ; cell short, not reaching half across wing ; 

 vein 7 just before end of cell, more than three times as far from 8 as
