198 LYCANID#. CASTALIUS. 
C. rosimon has a wide range, being found on the lower outer Himalayas throughout their 
length, and everywhere in British India except the desert regions of Sind. It occurs in Ceylon, 
in the Andaman Isles, on Kamorta and Nankowri in the Nicobar group, and from Assam to 
the Malay Peninsula and Siam, also in many islands of the Malay Archipelago. C. rosimon has 
a near ally in the ‘‘ Zyc@na ” hintza of Trimen, which is confined to South Africa. The male 
of this species is entirely blue on the upperside, being thereby at once distinguishable from 
Cy rosinion.

“J have taken only twelve males and one female on the northern slopes of the Nilgiris, 
confined to a quarter of an acre of ground, and evidently belonging to one brood. I found it 
common at the foot of the Nellyampathy Hills in Cochin in November, 1882.” (G. 7. Hampson).
