Apatura chevana, de Nicevillc, Butt. Ind. ii. p. 52 (1886). 
Male. TJpperside dark brown ; markings pale buff-ycllow. Fore wing with uiiiuterrupted dis- 
coidal streak, terminated by two oblique spots ; a transverse discal series of irregular-shaped 
spots, a submarginal row of small spots, and indistinct marginal narrow streaks. Hind 
wing with a broad transverse band, a submarginal lunulated band, and indistinct marginal 
narrow streaks. Body with pale buff-yellow waist-band and abdominal rings. Underside : 
fore wing with the markings as above, the interspaces ferruginous brown, suffused with 
dark brown posteriorly, except along the base of the costa and triangularly before the apex, 
which is pale nacreous blue : hind wing with a narrow transverse discal and marginal 
ferruginous-brown band, the rest of the wing pale nacreous blue, the broad transverse and 
lunulated submarginal band being paler nacreous white ; a black dot on lower part of disk. 
" Expanse 2| inches. Darjeeling." 
" The whole underside of this species is ver}' similar to that of Apatura ambica ; and Mr. W, 8. 
Atkinson has informed me that in fresh-captured specimens the upperside has also the 
beautiful reflected purple gloss visible in that insect." (Moore, 1. c.) 
The purple reflection on the primaries, referred to by Mr. Moore, is very 
well exhibited in all my Chinese examples of the male. In the female the 
upper siu'face is not shot with blue and the transverse markings are broader 
and pale straAv-coloured. 
The under surface of this species bears a remarkable resemblance to that 
of Apatura (Adolias) schrencki. 
Occurs at Moupin in "Western China and at Chang-yang in Central China, 
but is not common at either place. 
Refening to its distribution in India, de Niceville [1. c.) says: "A rare 
species in Sikkim ; the Indian Museum, Calcutta, possesses specimens from 
the Naga HiUs and Sibsagar in Upper Assam."

" Alis subdentatis, fusco-nigris ; fasciis duabus communibus externa punctis, linea longitudinali

angulo interiore violaceo-nigra ; posticis bifasciatis, inter illas 4-6 punctis argenteo- 
virescentibus.
