EHEBIA. 147 



arched ; apex generally broadly rounded ; termen convex or 

 straight, dorsum straight ; cell long, over half length of wing ; 

 veins 6 and 7 approximate at base, consequently upper disco- 

 cellular short, middle strongly curved inwards, lower long, oblique ; 

 veins 10 and 11 from before apex of cell, 12 inflated at base, 

 subcostal and median normal. Hind wing ovate ; costa and 

 termen widely arched (the latter in forms mani, kalinda and 

 sliallada strongly arched and rounded) ; dorsum very long, straight, 

 emarginate towards tornus ; tornus angulate, almost lobed (rounded 

 in mani, kalinda and sliallada) ; cell over half length of wing ; 

 discocellulars oblique ; vein 3 from well before, vein 4 from apex 

 of cell, vein 6 slightly closer to 7 than to 5 at base. Antennae 

 about half length of fore wing, club long and gradual (short and 

 flattened in mani, kalinda and shallada) ; palpi comparatively 

 short with porrect hairs anteriorly ; eyes naked ; intermediate and 

 posterior femora scaled, not hairy beneath. 



Key to the forms of Erebia. 



A. Males with secondary sex-mark of specialized 



scales on fore wing E. narasinglia, p. 148. 



B. Males without secondary sex-marks. 



a. Club of antennae spatulate as in European 



forms. 

 a'. With a large subtriangular yellow patch 



on upperside of fore wing E. mani, p. 148. 



b' . Without such patch. 



a 2 . Ochraceous-red patch on upperside of 

 fore wing large ; preapical ocellus 

 with a comparatively broad yellow 



ring E. kalinda, p. 149. 



b 2 . Ochraceous-red patch on upperside of 

 fore wing small ; preapical ocellus 

 without, or with only an obscure, 

 reddish-yellow narrow ring E. shallada, p. 149. 



b. Club of antennae not spatulate, subcylin- 



drical and gradual. 

 a . Ground-colour of fore and hind wings on 

 underside not alike, or if alike then 

 hind wing irrorated more or less with 

 greyish scales or short transverse dark 

 striae. 

 a 2 . Two large preapical and two tornal 



ocelli on underside of hind wing. ... E. hyagriva, p. 150. 

 b 2 . No preapical ocelli, or ocelli in a con- 

 tinuous series of five or six, on under- 

 side of hind wing. 

 a 3 . Underside of hind wingwith sinuous, 

 transverse, postdiscal and sub- 

 terminal dark bands, sometimes 

 obscure but always traceable.
