 " in being slightly paler in colour and in the underside of the abdomen 

 " having a curved, cerneous, black, shining ovipositor rising, as in H.

*' Habitat. — Sikkim and Bhutan Himalayas, from 1,500 feet to 5,000 

 "feet (Gr. C. Dudgeon). Foodplant, the young leaves of Mcesa. mm- 

 '' tana (D. C), Mcesa ramentacea (A. D. C.) and Mcesa indica (Watt.). 

 " Some species of Convolvulus is also attacked by this or an allied 

 *' form. " 



It is noteworthy that while the sexes are dissimilarly coloured in. 

 Helopeltis, the males in that genus being characterised by a more sedate 

 appearance than that of their partners, in Disphimtus both sexes are 

 very similar, if not indeed indistinguishable, in that respect. In IMo~ 

 pekis the pro-notum, &c., of the male is always, so far as known 

 blackish ; that of female, reddish or yellowish. In Disphinctus, on th© 

 other hand, both sexes of D. mcesanim are blackish in general aspect • 

 those of Z), Immeralis^ D. dudgeoni and D. formosus, reddish.
