II. — Description of a Moth of the Genus MiWonm from 

 Borneo. By A. G. Butler, F.L.S. &c. 



Eaely in the present year the Museum purchased a small 

 series of Lepidoptera from Borneo, amongst which was a 

 Milionia., allied to M. zonea^ and which I fully believed, at 

 the time when I selected it, to be the Burmese M. pyrozonis. 

 On comparison with the two species from Darjilingand Tenas- 

 serim I find it to be intermediate in character, and to be the 

 male of an insect which we have long had unnamed in the 

 collection, on account of the indefinite character of the locality 

 received with it — '' E. India." I propose to call this species 

 M. Sharpei.^ in honour of our ornithologist Mr. R. B. Sharpe, 

 throngh whose efforts the collection was submitted to us. 



Milionia Sharpei, sp. n. 



Size and coloration of M. zonea, of Darjiling, the wings 

 being velvety blue-black with metallic cobalt-blue streaks 

 upon the veins at the base ; the primaries with an oblique 

 bright orange belt and the secondaries with the outer third 

 of the same colour, with five large ov^al black spots immedi- 

 ately before the fringe. Body dull purplish black, the head, 

 collar, and tegulaj spotted and streaked with metallic blue- 

 green ; the abdominal segments edged with metallic blue ; 

 anal tuft grey ; legs with their upper surfaces brilliant metallic 

 blue. Expanse of wings 65 millim.

From 3f. zonea this species may readily be distinguished 

 by the belt of the primaries, which is quite a third narrower 

 towards its inferior extremity and more arched throughout, 

 and from both M. zonea and M. pyrozonis by the narrower 

 external orange area to the secondaries, upon which the spots 

 are oval rather than fusiform, and by the dark grey instead of 

 stramineous or dull white colour of the anal tuft. In M. pyro- 

 zonis also the colouring of the orange belts is considerably 

 redder ; but this naturally alters with age.
