Athi/Dia clu'vana, Moore, Proc. Zool. Soc. Lond. 18G5, p. 7G.3, pi. xli. fig. 1. 
Apatura c/ierana, dc Nicevillc, Butt. Ind. ii. p. 52 (188G). 
" Male. Uppei'side dark brown ; markings pale biiff-}ellow. Fore wing with uniuterrui)tod dis- 
coidal streak, terminated by two obliiiuo spots ; a transverse disoal 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 buft-ycllow 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 ])art of disk. 
" Expanse '2h inches. Darjecling.'' 
" The whole underside of this species is very similar to that of Apatura amhica ; and Mr. W. S. 
Atkinson has informed me that in fresh-captured specimens the uppersidc has also the 
lieautiful reflected purple gloss visible in that insect." (Moore, 1. c.) 
Tlie purple reflection on the primaries, referred to by Mr. INIoore, is very 
Avell exhibited in all my Chinese examples of the male. In the female the 
upper surface is not shot with blue and the transverse markings are broader 
and pale straw-coloured. 
The under surface of this species bears a remarkable resemblance to that 
of Ajyatura {AdoUas) schvencja. 
Occurs at ^Moupin in Western China and at Chang-yang in Central China, 
but is not common at either place. 
Referring to its distribution in India, de Niceville (/. c.) says: "A rare 
species in Sikkim ; the Indian Museum, Calcutta, possesses specimens from 
the Naga Hills and Sibsagar in Upper Assam."
