A EEVISION OF THE ORIENTAL HESPERIIDiE. 243 



Udaspes. 

 Udaspes, Moore, Lep. Cey. i. p. 177 (1881) ; Watson, P.Z. S. 1893, p. 113. Type folus, Cr. 



Antennae about half as long as costa; club gradual ; apiculus acute, about two-thirds 

 as long as the club. Palpi porrect ; third joint short, almost concealed. Fore wing : 

 dorsum longer than the termen, the latter nearly evenly curved ; vein 5 with its basal 

 portion receding from vein 6 and therefore arising much nearer 4 than 6 ; vein 2 

 arising before the half-length of the cell. Hind wing nearly as broad as long ; termen 

 evenly rounded; cell less than half as long as the wing. Hyaline spots present in both 

 wings. Tibial epiphysis present; hind tibiae fringed and bearing two pairs of spurs. 

 No alar sex-mark in the male. 



The two species known to us may be distinguished as follows : — 



Disc of the hind wing above white, completely surrounded by a broad dark brown 



border. Expanse about 42 mm fulus, Cr. 



Hind wing above fuliginous brown, with a sharply denned rhomboidal white spot on 

 the disc standing on vein 5 near the middle, and a white point just below it near 

 the basal third of cell 3. Expanse about 33 mm stellata, Ob.

Plesioneura stellata, Oberthiir, Etudes d'Ent. xx. p. 41, pi. ix. fig. 165 (1896). 



Hah. Msenia, % prope Ta-tsien-lo, E. Tibet (coll. Oberthiir). 



I am indebted to M. Charles Oberthiir for a specimen of this distinct species, 

 which he has recently received from his native collectors in Tibet. 



Actinor. 

 Actinor, Watson, P. Z. S. 1893, p. 108. Type radians, Moore. 



This genus was erected by Watson for the Halpe radians of Moore, an insect 

 combining with its own peculiar facies most of the other characters of Halpe, save that 

 the sex-mark is absent in the male and vein 2 of the fore wing arises near the basal 

 third of the cell. 



The pattern of the hind wing below is quite peculiar; the veins and two narrow 

 irregular straight transverse bands are yellowish white, the antemedian band starts from 

 the basal third of vein 1 b and passes over the base of vein 2 obliquely across the cell
