1 62 SOUTH-AFRICAN BUTTERFLIES. 



mou origin witli upper radial nervule) and terminating at apex ; upper 

 disco-cellular nervule much shorter than lower one. Hind-%oings nar- 

 rowly somewhat produced at anal angle, which is prominently but 

 bluntly lobed inferiorly ; hind-margin denticulate, and bearing at 

 extremity of submedian nervure a short or moderately long rather hirsute 

 tail, wider at its base ; costal nervure basally strongly arched, termi- 

 nating at apex ; subcostal nervure branched a little before middle. 

 Fore-legs of ^ very robust, — femur and tibia about equal in length, 

 both densely hairy (especially the latter, which has a terminal external 

 spur, and two internal terminal spines), — tarsus thick, scaly, with three 

 pairs of strong spinules beneath, several lateral spinules, and a rather 

 long terminal slightly- curved claw ; — of % less hii'sute, — the tarsus 

 longer, complete, with short curved terminal claws. Middle and hind 

 legs very robust, — femora and tibife moderately hirsute (the latter much 

 shorter and with short terminal spurs), — tarsi long and thick (especially 

 first joint), strongly spinulose beneath, with terminal claws short. 



This genus, which includes only the P. Harpax, Fab., Perion, 

 Cram., and Amangct, Westw., is nearly related to Dcudorix, Ceipys, and 

 Zeritis, but differs from all in having only three branches to the sub- 

 costal nervure of the fore-wings. In colouring and pattern, especially 

 on the under side, these butterflies nearly approach Zeritis, but are 

 further structurally distinguished from that genus by their longer, 

 more slender, distinctly clavate antennae ; shorter palpi ; more hirsute 

 head, body, and legs ; and prominently lobate anal angle of hind- wings. 



Hlibner gave the generic name of Axiocerses to Cramer's Perion, a 

 West- African species ; but I give preference to Chrysorijchia, seeing 

 that Wallengren was the first to diagnose the group, taking his Tjoctne 

 {=z Harpeix, Fab.) as the type. 



All the three species are known to inhabit Tropical Africa, and 

 Perion, Cram., has not been found out of that region. C. Harpax has 

 the widest distribution, ranging from the North-Tropical West Coast 

 to the eastern districts of Cape Colony ; while C. Amccnga appears 

 to be proper to the South-Tropical belt, but has occurred in Natal. 

 Both the South- African species are orange-red above with dark-brown 

 borders, but Harpax is darker in tint and has blackish spots ; while 

 beneath Amanga presents only a few silvery markings near the base; 

 in contrast to the numerous golden or brassy spots of Heirpax.

1 I pointed out that Wallengren's Thyra was quite distinct from Linne's insect, and sug- 

 gested [Trans. Ent. Hoc. Lond., 1870, p. 372) that it might be a well-marked ? Z. Chrysfaor,

 it to be the ? of Tjoane, Wallengr.
