Mr. A. G. Butler on a new Genus of Lepidoptera. 217 
CALLEREBIA, gen. nov. 
_ Gen. Erebie simillimum, differt forma et alarum scriptis, que multo 
illis Callistonis simulant ; antennis quoque tenuioribus minus dis- 
tincte clavatis, palpisque magis angulatis. 
The type species of this genus, C. scanda, greatly resembles 
Callisto; the markings are very similar, and the hind-wing 
anal angle is frequently produced and lobe-shaped. The genus 
is nearly allied to Erebia, 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.

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 posticee magis 
albido rorate ; ocellis subanalibus duobus ceecis distinctis (variat 
posticis minus productis ocellisque subtus minus oblique positis). 
Var. c. Alis posticis, non productis, velut in varietate a: subtus 
pallido nec albido roratis; ocellis posticarum analibus rotundatis 
distinetis nec oblique positis, ocelloqueé 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.

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.
