Underside more or less uniformly pale vinaceons rnsset, the discal interspaces 

 of the forewing and the discal and admarginal ones of the hindwing a little more 



clay-colonr. Forewing : interspace between median bars M' — M'- about one-third 



narrower than interspace between bars M-— (SM'), median bar R- — R' continnoiis 

 with bar R' — M', not mnch more proximal (as it is in marmax), costal edge 



more or less obvionsly scaled white at base. Hindwing : basal costal bar 



placed as in marmax ; median bars R' — M' continnons ; rest as in marmax ; discal 

 interspaces glossy. 



?. Wi7)gs, upprrside. Postdiscal, tawny interspaces of forewing narrower 



than in marmax, especially the upper ones ; the first white siibmarginal dot of the 

 hindwing larger than the second. 



Underside as in <?; median bar R' — R'' of forewing mnch closer to median bar 

 R' — R' than to discal bar R- — R^ ; first and second white submarginal spot wider 

 apart from the resjiective postdiscal slate-black bars than in marmax, the white 

 spot C— SC^ well marked, withont blackish bar at distal side (the bar present 

 in marmax). 



Penis with rather heavy denticnlatiou above, bnt withont the lateral patch of 

 teeth which is found in marmax ; penis-funnel much shorter than in marmnx, its 

 upperside concave to tip. 



Hab. Sikkim to Tenasserim. In the Tring Museum 21 6 S , 4? ? from: Sikkim; 

 Khasia Hills, Naga Hills ; Katha, Burma ; S. Shan States, Siam frontier ; Toungoo, 

 April. 



The specimens from Tenasserim have the discal bar R' — R' thinner than the 

 individuals from N. India, the bar not being much wider than the tawny postdiscal 

 spot at its distal side ; in these examples the black area is suddenly dilated in front, 

 but the black scaling is not so much extended as in the North Indian individuals ; 

 the median bars SC^ — R' stand abont midway between the cell and the black outer 

 area in the Tenasserim specimens. In the female sex from the same country the 

 discal bars SC — R' are much wider (according to Moore's figure) than in females 

 from North India. Dr. F. Moore considers these Tenasserim specimens to be 

 specifically distinct from aristogitoii, and calls them desa. It is possible that desa 

 represents, indeed, a geographical form of aristogiton. The penis and penis-funnel 

 are as in aristogiton. 



The specimens of marmax and aristogiton from North India are easily distin- 

 guished from one another by the colour of the underside of the wings, the shape of 

 the penis-funnel and the denticnlatiou of the penis; intergradations do not seem to 

 occur either iu Sikkim or Assam. From an examination of North Indian material 

 only one must, therefore, necessarily arrive at the conclusion that marmax and 

 aristogiton are two distinct species. But the matter becomes comi)licated, if one 

 takis into consideration the specimens from the Shan States and Tenasserim. In 

 these countries there occur, besides ordinary aristogiton, individuals which combine 

 characters of marmax and aristogiton, specimens which, besides, vary inter se very 

 much, and exhibit sometimes characters not found either in marmax or aristogiton. 

 The following specimens (S d) of the size of our smallest marmaxsLud aristogiton, or 

 even smaller, are in the Tring Museum :
