Mr. A. G. Butler on a new Genus of Lepidoptera, 217 



Callerebia, gen. uov. 



Gen. ErebicB similHmum, differt forma et alarum scriptis, quae multo 

 illis Callistonis simulant ; antennis quoque tenuioribus minus dis- 

 tincte clavatis, palpisque magis angulatis. 



The type species of this genus^ C. scanda, greatly resembles 

 CalUsto ; the markings are very similar, and the hind-wing 

 anal angle is frequently produced and lobe-shaped. The genus 

 is nearly allied to Er-ebia, but has a totally different aspect; 

 and as it does differ in several structural details, I have thought 

 it best to concede to the wishes of my brother lepidopterists by 

 separating it as a distinct genus. 



Sp. 1. Callerebia scanda. PI. IV. figs. 8 & 9. 



Erebia scanda, Kollar, in Hiigel's ' Kaschmir,' iv. pt. 2. p. 452, taf. 17. 

 figs. 3,4 (1844). 



Hab. Cashmere, Northern India. B.M. 



Var. a. Alis omnino pallidioribus, fasciis subtus subobsoletis ; ocellis 

 posticarum duobus analibus rotundatis valde distinctis oblique 

 positis. 



Var. 6. (? an C. annada, Moore). Alis piceis marginibus pallidioribus; 

 angulo anali posticarum valde producto : subtus posticse magis 

 albido roratae ; ocellis subanalibus duobus csecis distinctis (variat 

 posticis minus productis ocellisque subtus minus oblique positis). 



Var. c. Alis posticis, non productis, velut in varietate a : subtus 

 pallido nee albido roratis ; ocellis posticarum analibus rotundatis 

 distinctis nee oblique positis, ocelloque minimo discali simili (va- 

 riat posticis subtus uniformiter fuscis ; ocellis duobus discalibus 

 distinctis, omnibus albo pupillatis). 



This species varies considerably : it would be quite impossible 

 to link the two extreme varieties in our Collection, did we not 

 possess all the intermediates, as they are far more distinct than 

 many species. 



Sp.? 2. Callerebia annada. 



Erebia annada, F. Moore, Cat. Lap. Mus. East Ind. Comp. p. 226. n. 475 



(1857). 



Hab. Bootan (Moore). 



Sp.? 3. Callerebia nirmala. 

 Erebia nirmala, F. Moore, Proc. Zool. Soc. London, p. 501. sp. 91 (1865). 

 Hab. North-western Himalayas (Moore). 



As I have not yet seen the types of these two forms, I am 

 unable to say whether or not they are identical with any of the 

 varieties of scanda.
