grey ; cilia grey ; thin tails from veins 1 and 2 of hind wing, the former the broader 

 and shorter, about 4mm. in length, black with white edges and tips. 

 Underside : both wings satiny grey with a postmedial, thin, black line across 

 both wings, composed of small hmules betAveen the veins, six on the fore wing, 

 seven on the hind wing. Fore Ming : this postmedial series of black lunules 

 beginning further from the apex, ending nearer the tornal angle, nearly straight ; 

 followed by a sul marginal series of greyish, oblong spots faintly margined Avith 

 w^hite. Hind wing ; the postmedial series further from the outer margin than 

 on the fore wing, more irregular in that the second pair of lunules are displaced 

 slightly outwards, the seventh being V-shaped with the convexity outwards 

 ^nd rounded at the apex ; this lunule series continued to near the anal margin 

 by a straight, black bar of similar width, displaced slightly outwards, starting 

 from vein 1 and running slightly upwards ; outside this a more distinct series 

 of submarginal, oblong, greyish spots than on the fore wing, interrupted in 

 interspace between veins 2 and 3 by a circular, jet-black spot on an orange 

 patch which occupies the breadth of the interspace and is straight- 

 bordered inwardly ; followed by another, rather larger, jet-black, transversely 

 broadly oval spot occupying the anal lobe and bordered inside by an orange 

 lunule and with a narrow, metallic streak on it externally ; the space between 

 these two spots is a group of silvery specks on a hoary ground ; there is also, 

 besides, a faint marginal series of oblong, greyish spots on both wings. 

 Antennie abruptly terminated by a short point, brown with a ferruginous tip 

 and marked on one side with transverse, greyish dots ; body greenish blue 

 above, with delicate, white hairs beneath.— Female (PI. H., fig. .53o). Upper- 

 side : both wings sordid white with pale azure-silvery scales at the bases of both 

 wings. Fore wing: with broader, black-brown borders than in the male, but 

 similar. Hind wing : the costal margin broadly pale brown ; a postmedial 

 series of 5 black lunules in interspaces from vein 2 to vein 6 ; a sub- 

 terminal similar series with the two at the anal end larger, romider, more 

 prominent and preceded by an obsolescent broAvn lunule on the lobe. Under- 

 side : both wings as in the male but the marking bolder. Expanse : male, 30mm. 

 to 45mm ; female, 37 mm. to 45 mm. 



^(/gr.— -Hemispherical in shape, minutely rugose, -^vhite ; under a lens the 

 roughness is seen to be due to many smooth, tubercle-like prominences. 

 B. O. 7 mm. 



Larva. — (PI. II., fig. 26). — The sliape is abnormal in that the larva is nearly 

 as broad at segment 10 as it is at segment 5 which is the broadest part ; it has a 

 " waist " that is, being narrowed between segments 5 and 10. The head is 

 hidden under segment 2, is dark brownish-yellow in colour, round in shape, 

 and shining. Segment 2 is, generally speaking, semicircular in shape with a 

 short, rounded, tumidity or lobe subdorsally and laterally on the front margin, 

 4 in all round the free edge and it has an hexagonal dorsal depression in the 

 centre with a shining bottom, this depression being nearly as long as the 

 segment and half its breadth (transversely to length of larva), the depression 

 having a light, dorsal line on it ; the segment ascends gently to the hinder 

 margin ; segments 3, 4, 5 rise up in steps so to speak from 2 forming with seg- 

 ment 6 which is not so high as 5 a hood-shaped piece ; dorsally the body slopes 

 down to segment 10, rising into a kind of knob and thence, over 12-14 descending 

 in a curve to the anal extremity ; laterally, the outline of the body is : 

 broadening out in a curve to segment 5, then bending round this broadest 

 part to narrow again in a curve to before segment 10, then widening out again 

 rapidly to narrow more suddenly still to the rather narrow, short, trapeze- 

 shaped anal segment, the lateral margins of the trapeze being shortest, the 

 posterior margin, the extremity of body that is, somewhat longer, the anterior 

 margin longest ; segments 3, 4 are dorsally flattened forming a sloping, yellow
