border of exceedingly variaLlo devolopmenl", and their under side has a 

 shining dull-greenish tint, with a terminal disco-cellular spot in tlie 

 hind-wings, so that specimens with scarcely any blackish border look 

 very like Callidryas Florclla. E. Pilaris (which I have not had the 

 opportunity of examining) is described by Doubleday {op. cit., p. 65) 

 as having " the wings nearly as round as the genus Poiitia, and of as 

 delicate a texture ; the apex of the anterior just touched above with 

 black, below varied with brown ; the posterior wings above immaculate, 

 below sometimes nearly immaculate, at others varied with large clouds 

 of satiny-brown and silvery- white." 



The four species found in South Africa all have a tropical range, 

 Argia and Buquetii both inhabiting alike the East and West Coasts, 

 while Lecla and Cleodora, with an extensive East-African distribution, 

 do not appear to have been hitherto recorded from West Africa. They 

 are all found on the south-east, Leda and Argia not spreading farther 

 south-westward than the Bashee Eiver, but Clcodora extending to Van 

 Staden's River, and Buquctii to Knysna, and even straggling to Cape 

 Town. On the wing they are decidedly swift, but constantly check 

 their onward flight to visit flowers. 



The larva of E. Clcodora has been found on Capparis Zeylicri, but 

 I have not seen either specimens or drawings of it.

^ White, yellowish-white, or pale-yellowish, tvith a black hind-mar- 

 ginal border, variable in ividth and irregular on its inner edge. Fore- 

 wing : base usually marked very faintly and narrowly with blackish ; 

 hind-marginal border varying from very narrow to broad, — wide apically, 

 rather abruptly narrowed on third median nervule, and thence either 

 tapering to a point or to a narrower or broader termination (in accord- 

 ance with the less or greater width of the border) to posterior angle ; 

 inner edge very variable and irregular in outline, generally more or 

 less denticulate on nervules and excavate between them, — always a 

 very marked and conspicuous prominence or projection (rounded, sub- 

 acute, or truncate) immediately above third median nervule ; in apical 

 extremity of border two spots of the ground-colour, — a small one 

 between second and third subcostal nervules, and a larger one (nearer 

 apex) between fifth subcostal and upper radial nervules. Hind-icing :
