ibroadly and a tenniiial edging that occupies about oue-third of the wing 

 bUick ; the remainder of the wing white shaded with dusky-greyish 

 which, in certain lights, has a beautiful, opalescent bhie iridescence ; 

 .uu the inside of the terminal edging is a dift'use, dusky area defined in- 

 wardly by a line running from the edge of the black, at vein 4 to about 

 middle of the inner margin which encloses near the black outer margin spots 

 .of whitish in interspaces 1, 2 and o, one in each. Hind wing: costal 

 margin above a line through the middle of the cell and above vein 6 duskj'- 

 black ; posterior portion of the wing dusky-bluish, veins prominently black ; 

 a comparatively well-detined, transverse, postmedial series of dusky-black 

 dunules edged inwardly and outwardly by similar series of finer lunules, 

 all inwardly convex, followed by a subterminal series of dusky-black spots 

 edged outwardly thinly with white ; an auticiliary, black line ; the spots 

 decrease in size upwards, those in interspaces 2, '■) being most prominent 

 and, occasionally, jet-black, those in interspaces I very small. Tail thread- 

 like, black tipped with white. Undcrsidr' : The same as male, i:>erhaps 

 slightly browner ; the transverse, white lines broader, the bases of cilia 

 whiter ; otherwise as in the male. There is no appressed hair on the disc 

 <}f the wings except at the base and below vein 1. There is often a dark 

 dine along the discocellular nervules of the hind wing. Palpi black above ; 

 eyes rimmed with white ; frons blackish ; antennte black above, the club 

 also black throughout with a white band near apex ; thorax above black 

 iwith brownish hairs in female, whitish in male ; abdomen brown. Beneath : 

 palpi with stiff mixed black and white hairs ; antennae finely banded white, 

 reaching on to the sides ; thorax brownish-yellow in the male and w'hite 

 ;in the female ; abdomen whitish. The legs are striped longitudinally 

 black and white (also in atrata). Expanse : 28-31 mm. 



Colonel Bingham has described the female of this species as the female 

 of atrata and, of course, the female of atrata as plumbeomicann. He gives 

 the habitat as Tenasserim ; Assam ; Chittagong hill-tracts : the Andamans 

 :and Nicobars. To this is now added Kanara District in the Bombay Pre- 

 sidency. 



The life-history of the species is as follows : — 



Eyij. — Txirh-Aw-sliaped ; the top slightly depressed. Surface shining, 

 covered all over with diagonal more or less parallel rows of small knobs 

 with rounded tops, each knob connected with the surrounding ones by 

 'little, raised ridges or lines that meet in the interspaces at various angles 

 and the interspaces formed by their meeting on the fiat so to speak, are 

 again covered with minute cross lines or ridges ; without, however, any 

 signs of thickening at the intersections of these minute lines ; the knobs are 

 very numerous, are somewhat variable in size, rather flattened on the top 

 with a minute hollo v in the centre of each flat top ; they are separated from 

 •each other by their own breadth or four wall widths; they are largest at the 

 rim and the outer circumference of the egg and down the sides, decreasing 

 in size and prominence inwards to the micropyle which is, of course, central 

 •and of the size of, say, the interval between three of the largest knobs : 

 <the bottom shagreened-cellular ; the rows of knobs radiate outwards in 

 slowly diverging curves like a catherine-wheel firework going round and 

 there are 16 such lines round the whole egg : from micropyle out to rim 

 there are about *J cells and three cells from base to rim — all these cells on 

 the perpendicular sides are nearly perfectly quadrangular and the knobs 

 •are low and small, tlie really prominent one being situated at, and 

 for a short space on each side of, the brim. Colour pure enamel-white — 

 •really honey-yellow but this colour is not always strikingly visible 

 (because of the multiplicity -of white knobs and lines. B: <). •"i2 mm.; 

 H : O. 2.'5 nnii.
