 4, 4* Cab. Mus. Dom. Banks. 

 Guer. Voy. Abyss, vi. 353. 



Female. Length 8-10^ lines. — Black : strongly punctured, 

 the vertex and disk of the thorax smooth and shining ; wings 

 clear hyaline, the anterior margin of the superior wings having 

 a black stripe, extending from the base to the apex, a narrower 

 stripe on the inferior margin of the superior wings, and slightly 

 extending over the anterior margin of the posterior pair, runs 

 from the base of the wings to the apex of the anal cell ; the 

 black stripes have a brilliant purple iridescence. Abdomen 

 shining, strongly punctured at the sides, base, and apex, more 

 finely and distantly in the middle ; the sides and apical segments 

 fringed with black pubescence. 



Hab. Port Natal 5 Abyssinia. 



Note. — The neuration of the wings in this species is very in- 

 constant : of four specimens received from Port Natal, one has 

 the neuration of the first division ; the other three have three 

 discoidal cells, but the second recurrent nervure unites with the 

 first, and is received by the second submarginal cell ; this species 

 would therefore fall into Guerin's subgenus Liacos. 



The t3rpical specimen in the Banksian Cabinet having been 

 carefully examined, it appeared necessary to give the above de- 

 tailed description, that of Fabricius in the Entomologia Syste- 

 matica being too general to answer the purpose of correct dis- 

 crimination.

In this species the two recurrent nervures unite, and are re- 

 ceived in a single nerve by the second submarginal cell.
