the greatest height is at the thoracic apex although only slightly higher 

 than at segment 6 ; the anal end is rounded, as visible from above 

 about the same breadth as the front of the pupa, segment 12 is 

 steeplj' sloping, segment 14 slightly turned under ventrally at the ex- 

 tremity. Surface slightly shining, the segments well-marked if thin, 

 very minutely reticulate-rugose and very thinly so ; under the lens covered 

 with minute, erect, blunt-topped, white-glassy hairs all over, specially 

 dense on the margins (when looked at from above) and at both ends of the 

 pupa, the hairs in front of the spiracles of segment 2 being, a few of them, 

 plumose or feathered. Sjnracles of segment 2 linear-oval in shape, rather 

 prominently raised, white in colour ; the others are oval in shape, raised, 

 small and light-coloured. Colour of pupa is light yellowish-rose with a 

 brown tint with a blotchy, dorsal, black line, a black shoulder-patch, 

 another patch laterally on segment 5, a lateral dot above each abdominal 

 spiracle ; spotted besides all over, on wings and everywhere else, with 

 black ; the wings always lighter, yellowish or greenish, L : 8 mm.; B : 

 •■'> nmi.; H : .3 mm. at thorax, A slighter pupa than that of N. atrata. 



Habits : — That eggs are laid on the very youug shoots and gener- 

 ally towards the axils of the leaf-stalks or on a leaf-bud. The larva 

 lives between the folded leaves, often getting in betv.-een the two 

 halves which are folded somewhat tightly together when very 

 young ; eats in round holes right through both half-leaf portions ; 

 afterwards, when grown, lives on the undersides of the tender 

 leaves which it only eats. It is attended by ants but only fitfully. 

 The pupation takes place generally in a w^ell-sheltered place on the 

 underside of a leaf, on an old withered leaf, &c., often near or on 

 ^he gTonnd ; and the attachment is b}'" the tail and a body-loop. 

 The habits of the butterfl}^ are those of Nacachiba atrata precisely 

 in flight, resting position, localities, &c. The onl}'- difference is that 

 this present species has chosen for the food of its larva the legumi- 

 nous Wafjatea spicata instead of the myrsinaceous Emhelia robusta ; 

 l)oth these plants are common on the Western Ghats in Bombay 

 though the former seems to be more particularly fond of laterite 

 soil. Waga.tea is a more local climber than Emhelia. Perhaps, on 

 second thoughts tlie butterfly is a little stronger on the wing than 

 atrata and is, seemingly, confined to the regions of heavj^ rainfall 

 and jungle. It is quite plentiful on the coast in the Kanara Dis- 

 trict, Bombay, and in also found up to 2,500' on the Ghats.
