NEW INJURIOUS PHYTOPHAGA FROM AFRICA. 475 



Argopisies sexvittatus, sp. n. (fig. 4). 



Rounded, convex, testaceous ; prothorax testaceous, finely and closely punctured ; 

 elytra fulvous, a little more strongly punctured than prothorax, sutural margin 

 black, lateral margins broadly testaceous, with inner margin narrowly black from 

 base of suture to apex, a narrow black vitta down middle of each el^^tron ; underside 

 fulvous. Length, 4-40 mm. 



The (^ only differs in its slightly smaller size and ventral segments, the last 

 ventral being very large, strongly incised and deflexed, and longitudinally sulcate 

 (fig. 4, a) ; the 2nd, 3rd and 4th segments are much contracted in the middk. 



This species is closely allied to A. oleae, sp. n., but differs in having the head 

 and prothorax testaceous, the elytral punctures are slightly stronger, the lateral 

 margins are broadly testaceous, with the inner margins black, and the elytral vittae 

 are narrower and more sinuate.

Cape Province : Stellenbosch, 11.x. 1920, 2 (^^ and 1 ? on wild olive, 3 ?? vars. 

 {Dr. C. K. Brain). Natal : Potgieter's Farm, i.l900, 1 ? {H. Bell-Marlev). Orange 

 Free State : Bloemfontein, 6.n.l916, 2 ^^, 4 ?? (/. C. Faiire). 



The species is a leaf-miner on wild olive. 



The six specimens from Bloemfontein do not vary inter se, but differ from the 

 type from Stellenbosch in the black line of the lateral margins extending from the 

 apex to little more than a third of the lateral margin. Three specimens collected 

 by Dr. C. K. Brain at Stellenbosch, 11.x. 1920, all females, have the elytra and 

 prothorax blue-black, with a broad testaceous border. These are evidently only 

 a variety of ^4. sexvittatus, as I can find no structural difference. 



This species has stood in the British Museum collection since 1867 under the 

 MS. name of Pseudococcinella sexvittata, Chevr., and I have thought it better to 

 retain the specific name, as it has probably been widely circulated. This specimen 

 came from the Hamlet Clark collection, which contained Chevrolat's collection.
