256 SOUTH-AFRICAIT BUTTERFLIES. 



area almost wholly fuscous varied with bluish ; while all the spots 

 and other black markings are very much thinner, and the greenish- 

 white much brighter, than in Benr/udm throughout. 



From the West-African Crenis Amulia (Cram.) the species de- 

 scribed is easily separated by its much bluer tint on the upper side, 

 and by the much wider and greenish-white instead of bluish-white 

 markings on the under side, although in the feature of the almost 

 uniform ochre-yellow of the under side of the fore- wing the two species 

 approach each other. 



The only examiile of this very beautiful Orenis that I have seen is the $ 

 above described, which was taken by the late Mr. J. J. Monteiro at Delagoa 

 Bay in 1877, and was acquired for Mr. Hewitson's collection, now in the 

 Bi'itisli Museum. Mrs. Monteiro has informed me that this butterfly was 

 captured on the wing " a little overhead," at a spot called Poulana, and that 

 no other example was met with. 



In a paper in the AiinaU and Mag. Nat. Hist, for August 1883, INIr. A. G. 

 Butler records the receipt of " a splendid male " of G. Rosa from the Victoria 

 Nyanza, but does not note in what respect it differs from the female.

Imago. — Head of moderate size, hairy, with a small tuft of longer 

 hairs at base of each antenna ; eyes usually hairy ; palpi much elon- 

 gated, not compressed laterally, separate throughout but converging 

 slightly at tips, — second joint tufted above and finely hairy beneath, — 

 terminal joint unusually long (about half as long as the second), rather 

 blunt at tip, bent at a very obtuse angle with second joint and pro- 

 jecting horizontally about level with top of head, densely scaled ; 

 antennce of moderate length, with a gradually formed but rather short, 

 slender, laterally-flattened club, ending obtusely. 



Thorax rather slender ; back shortly pilose anteriorly and poste- 

 riorly ; breast rather scantily hairy. Fore-wings : generally more or 

 less produced apically, usually angulated at extremity of lower discoidal 

 (radial) nervule and prominent at extremity of second median ner- 

 vule ; costa but little arched ; apical angle well marked ; hind-margin 

 dentated, usually more or less excavated in middle ; inner margin 

 very slightly hollowed about middle ; costal nervure strongly swollen
