194 LLOYD'S NATURAL HISTORY. 



where it flies very swiftly in March and April, appears to be a 

 local insect, and is generally scarce in European collections. 



It measures from 2 to 2^ inches across the fore-wings, 

 which are of a sulphur-yellow colour above in the male, the 

 tip of the fore-wings being narrowly black, between which 

 and the end of the cell, which is marked by a small black dot, 

 is a short black band running from the costa ; the under side 

 of the wings is greenish -white. The female varies from pale 

 yellow to nearly white, and the apical spot of the fore wings 

 is orange.

Antennae with an oval flattened club ; palpi rather short, 

 bristly beneath ; fore-wings triangular, with the tip slightly 

 rounded off; hind-wings rounded; fore-wings with the sub- 

 costal nervure four branched, the two first branches emitted 

 near together before the end of the cell, the upper discoidal 

 nervule rising from the end of the cell, the upper disco-cellular 

 nervule being thus rendered obsolete, as is also the case on 

 the hind-wings. 



Pupa less boat-shaped than in Euchloe, and with prominent 

 wing-covers. 



This genus is met with throughout Africa, the Mediterranean 

 district excepted,* but in Asia Minor it is not found, though it 

 extends through Arabia to India and Ceylon, where, however, 

 the species are far less numerous than throughout Africa south 

 of the Sahara. 



* The single Algerian species of the group belongs rather to Abccis>
