none of the other nervures show any enlargement. I cannot 

 follow Wallengren in separating these insects from the Genus 

 Erebia, as they only seem to differ by exhibiting as a 

 constant character the enlarged costal nervure (which in the 

 European group is as often simple as swollen). Still less 

 can I agree with him in considering the species Panda of 

 Boisduval as the type of a new genus (Pkysc&neura), the 

 only distinctions from Pseudonympha pointed out in his own 

 detailed diagnosis being the slightly inferior origin of the 

 first discoidal nervule (" Costa 6 "), and the less-marked 

 angulation of the disco-cellular nervule (" costula transversa 

 cellule "). The more slender club of the antennae is not a 

 character of consequence> E. Cassius and others of the genus 

 also presenting it. 



These insects are usually of a sombre hue ; the most 

 lively-looking being E. Panda and Cassius, especially the 

 former. The commonest are E. Sabacus, Cassius, and 

 Hippia ; to which may be added, near Cape Town, E. 

 Hyperbius. The other three can scarcely be expected to 

 occur further South and West than British Kaffraria.

Dark-brown, with a violaceous gloss : fore-wing much 

 coloured with deep-fulvous, hind-wing with a small fulvous 

 patch. Fore-wing : fulvous occupies the same space as in 

 E. Sabacus, but is not externally dark-edged, nor ever 

 divided into two patches, though its cellular portion is often 

 much obscured in $ ; an apical ocellus, white-bipupillatc, 

 and ringed indistinctly with pale ochreous, marks upper 

 portion of fulvous, q uite as in Sabacus. Hind-iving : on 

 median nervules an ill-defined fulvous patch, enclosing two 

 small unipupillate ocelli (one or both often wanting). Both 

 wings, but especially hind-wing, clothed with fulvous huirs
