A REVISION OF THE ORIENTAL HESPERIID^E. 269 



by the sex-mark of the male, which is in the form of " a patch of long recumbent hairs 

 on the uppersicle of the hind wing, attached along vein 8 from close to the base of 

 the wing."

This is a genus established by Mr. de Niceville for semamora, Moore, and watsonii, 

 de Nicev. Both these species have been placed in the genus Parnara ; and if the form 

 of their antennse, palpi, and wings, and the venation be compared with that of some 

 species of Parnara, such as P. austeni, their relationship to that genus will at once be 

 evident. The chief point of distinction lies in the pattern of the hind wing below, of 

 which the main diagnostic feature is the fact that the discoidal cell is wholly white, and 

 cells 4—5 and 6 are white except at the apex. The male of semamora has a patch of 

 long upturned hairs near the middle of the dorsum of the fore wing below ; the same 

 sex of watsonii has no alar sex-mark.

We have seen, from the collection of Col. Adamson, an aberrant male specimen of 

 this species taken at Kalewa, on the Chindwin River, in October ; on the upperside 

 of the hind wing the white patch is quite as extensive as in some specimens of 

 semamora, but the hind wing below, although very much abraded, still retains the 

 characteristic pattern of watsonii; the clasp-form can, without dissection, be made out 

 sufficiently well to show that in this respect it agrees very well with ivatsonii, and is 

 absolutely distinct from semamora.
