HYPOLYCJENIN^. 135 



small round deep black spot, crowned witli ferruginous ; body above very pilose, 

 pale blue, beneath ochreous. 



0. seta is near to 0. ogyges, de Niceville, but differs in many important particulars. 

 The coloration of the upperside is different, it is not iridescent, and is never emerald- 

 green in any light ; in the fore wing there is less blue on the inner margin, the black 

 area on the outer margin being broader, and there is more blue in the discoidal cell ; 

 the " male mark " is less prominent. On the hindwing the outer margin is more broadly 

 black, in 0. ogyges it bears a black anteciliary thread only. On the underside the 

 ground colour of both wings is redder, the discocellular nervules are marked with a dark 

 line, the discal line is more irregular, and in the forewing is further removed from the 

 outer margin. 



It appears to be allied to Myrina deudorix, Hewitson,* from Mindanao in the 

 Philippines (Hewitson and Semper), but that species has the discal line on the under- 

 side of both wings " white bordered inwardly with brown." On the upperside the two 

 species hardly differ. 



Described from two male examples in my collection, (de Niceville.) 



Expanse of wings, $ 1^-q inches. 



Habitat. — Burma. 



Described from specimens taken at Maulmein and Tenasserim ; we have not seen 

 this species, the types being in the Indian Museum, Calcutta, we therefore figure copies 

 of de Niceville's figures.

Imago. — Male. Upperside cerulean-blue, of a very bright and beautiful shade of 

 colour. Forewing with a large quadrate shining sexual mark at the end of the cell, 

 limited hindwards by vein 2, and upwards by vein 6, a black costal band, its lower 

 edge running slightly into the cell, and heavily round the cell end, then upwards over 

 the sexual mark and round it down to vein 2, then in a much narrower form to the 

 hinder angle, the sexual patch in some lights has a coppery tint. Hindwing with the 

 costal space and abdominal fold grey, a narrow black band on the outer margin 

 which slightly thickens round the apex of the wing ; anal lobe and inner tail greyish-
