Wings below glistening grey, the internal area of primaries whitish, 

 the costal border and external margin in the female varied with 

 ochreous ; the secondaries in this sex also somewhat paler, slightly 

 yellowish towards costa, especially from the middle, and crossed by 

 an irregular oblique subapical grey band ; a dark grey spot at end 

 of cell : body below milk-white, tibise and tarsi barred with grey. 

 Expanse of -ndngs 19-20 millim. 



S 5 , between Voi and ISTdi, 88 miles from Mombasa, 4th June, 

 1897. 



In 1884 we received a slightly smaller pair of this species from 

 Accra ; but these are all that I have seen of it. 



141. Tar ACHE sp. 



2 . Probably new, but too imperfect to describe ; it is nearly 

 related to a very beautiful unnamed female (also from British East 

 Africa) in the Museum collection ; but differs in so many details 

 of colouring, that I cannot venture to regard it as a variety of that 

 insect ; also, in this genus, in which the sexes often differ to a 

 marvellous degree, it is not satisfactory to describe from a female 

 alone.

Acontia admota, Felder, Eeise der Nov., Lep. v. pi. cviii. fig. 31 

 (1875). 



Samburu, 31st October, 1896. 



I have previously seen this insect from extreme North and 

 from South Africa ; but it is new to us from East Africa. In fresh 

 examples the markings on the primaries are bright olive-green ; 

 the figure in the ' Novara Voyage ' is not characteristic.
