allopatric indicata. Distinguished structurally from both species by the form of 

 the valves in the male genitalia and by the form of the sterigma in the female 

 genitalia. 



The syntypic series consists of three females, not one male and two females as 

 recorded in the original description, and the date of capture is June 1896 not Febru- 

 ary 1896. The female recorded as having 'the sinus of the fore wings bilobed 

 and shallow' has proved to be a specimen of regularis sp. n. One of the other two 

 females has been selected as lectotype and is designated above. 



The specimens recorded by Swinhoe (1904 : 515) represent two species; those 

 from Nigeria zxe flavicosta, the female from Sierra Leone is indicata sp. n. 



The specimen recorded by Hampson (1910 : 470) from Zambia cannot now be 

 recognized, but it was unlikely to have represented flavicosta.

$ $. Apparently identical in colour and pattern with flavicosta. Distinguished externally 

 in the male by the slightly longer pectinations of the antennae and structurally in both sexes 

 by the genitalia. The distributions of the two species do not appear to overlap. 



Q* genitalia (Text-figs 101, 102). Distinguished from flavicosta by the form of the valves; 

 the digitate apex of the left valve is smooth, not scobinate as in flavicosta; the right valve
