than was expected ; not only does it occur in Sikkim, Beeling 

 in North Tenasserim, the Ataran Valley, and on the Daunat Range 

 in Middle Tenasserim, but also in Perak in the Malay Peninsula, and 

 in N.-E. Sumatra and Java. 



Described from a single example obtained on the 12th July, 1892, 

 by Mr. S. Robson, after whom I have much pleasure in naming the 

 species. 



Genus GE, nov. 



M.ALE. Forewing, costa regularly and slightly arched throughout 

 its length ; apex rather rounded ; outer margin nearly straight, except 

 from the apex of the wing to about the termination of the lower 

 discoidal nervule where it is at right-angles to the costa ; inner angle 

 rounded ; inner margin straight, as long as the outer margin ; costal 

 nervure ending before the apex of the discoidal cell ; subcostal nervules 

 arising at slightly decreasing distances apart ; discoidal cell narrow, 

 extending to beyond the middle of the wing, not reaching to two- 

 thirds the length of the wing from the base ; upper disco-cellular 

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

 straight, strongly inwardly oblique ; lower disco-cellular also straight, 

 in the same straight line as the middle disco-cellular, of about the 

 same length ; second median nervule arising well before the lower end 

 of the cell ; first median arising nearer to the lower end of the cell 

 than to the base of the wing ; submedian nervure straight ; a circular 

 sexual dense tuft of hairs placed on the upperside of the wing towards 

 the base of the first median interspace ; the area to which the bases 

 of these hairs is attached shows prominently on the underside as a 

 circular disc. Hindwing, longer than broad ; costa greatly arched at 

 the base, less so to the apex of the wing ; apex rounded ; outer margin 

 rounded, but considerably excised about the termination of the first 

 median nervule ; anal angle rather acute; abdominal margin straight; 

 costal nervure slightly curved only, terminating at the apex of the wing ; 

 first subcostal nervule arising long before the apex of the cell ; upper 

 disco-cellular straight, upright ; lower disco-cellular straight, outwardly 

 oblique, longer than the upper ; discoidal nervule present ; second 

 median nervule arising a little before the lower end of the cell ; first 

 median arising about twice as far from the second as the second does
