52 L. de 'NicoYillo'^Butterjiies from the Itido-HIalayan region. [No. 1, 



Heteropteriis, Dumeril, PamjpMla, Fabricius, and Cyclopides, Hiibner. 

 Ochus is apparently nearest to PampMla, of which the type is P. palcemoi, 

 Pallas, and from which it is abundantly distinct ; the costa of the fore- 

 wing is greatly arched instead of straight, the apex is rounded instead 

 of being acute, the outer margin is more rounded, the discoidal cell is 

 much shorter and broader ; the hindwing is more oval, the discoidal 

 cell is again much shorter, the discoidal nervule is obsolete, in P. palcB' 

 man it is present ; besides many other minor differences. The imago 

 rests with wings closed over its back. Of all the Indian species of 

 HesperiidcL', 0. suivittatus probably has the feeblest flight, appearing on 

 the wing to be a dark-coloured, low-flying lyctenid, similar to a female of 

 the wet season foi^m of Zizera malm, Kollar, or some other dark-coloured 

 " blue." Lieut. Watson suggests in Proc. Zool. Soc. Lond., 1893, p. 97, 

 that " Cyclopides " suhvittalus belongs to the North American genus 

 Ancyloxypha, Felder, or to one closely allied to it ; but this is not the 

 fact, Ochus is widely distinct from that genus, and comes into the first 

 section of the subfamily instead of the second containing the genus in 

 question.

Habitat : Darjeeling ; Salween district, Moulmain, 'Bxivm.u,'(suhvitta' 

 tiis); Khasia Hills (subradiatiis, Moore) ; Kumaon {Bolierty) ; Sikkim, 

 Bhutan, Assam, Burma {coll. de Niceville). 



It is, I think, quite impossible to separate 0. suhradiatus from 0. sub- 

 vUlalus. Mr. Moore places the former in the middle of the region 

 inhabited by 0. suhvittatus. I have caught it as far south as the Dawnat 

 range and Meple in Middle Tenasserim, in the month of October.

Habitat : Runang Pass, south-east side, about 13,000 feet elevation, 

 Busahir (Moore) ; Khibber Nala, about 16,000 feet elevation, Spiti

As I have already figured the female of this rare species, I now 

 take the opportunity to figure the male. Mr. P. W. Mackinnon through 

 bis native collectors obtained three male specimens, of which he has
