Of the Indian genera with two subcostal nervules only to the fore- 

 wing, Britomartis seems to be nearest allied to Hypolyccena, Felder, of 

 which U. tmolus, Felder, from the Philippines, is the type. Herr 

 Georg Semper considers H. tmolus to be a " Variety" only, or more 

 properly a " Local race" of H. erylus, Godart. From the latter species 

 B. cleoboides differs in the forewing being shorter ; the " male-mark" 

 somewhat differently placed, occupying a much larger area in the cell ; 

 the second subcostal nervule arises twice as far from the base of the 

 first subcostal as from the origin of the upper disco-cellular nervule,* 

 in H. erylus the exact opposite obtains ; the second median nervule 

 arising further from the lower end of the cell ; and the eyes being 

 apparently naked instead of hairy. From the genus Chliaria, Moore, 

 of which " Uypolycosna" otliona, Hewitson, is the type, it may be 

 known by the naked eyes, and by the second subcostal nervule of the 

 forewing being far removed from, instead of close to, the first sub- 

 costal at its origin ; the hindwing, also, is longer and narrower. 

 Britomartis has male secondary sexual characters, which Chliaria 

 entirely lacks.

Mr. Elwes says of this species that it has " A large round velvet 

 patch free from blue scales in the cell of the forewing and with raised 



* Actually there is bo upper disco-cellular nervule in this gem s, what I have described 

 above as that veinlet being the basal portion of the urper discfidal veinht, the middle 

 disco-cellular veinlet arising from the upper discoidal some distance from the base of the 

 latter.
