100 SMALL PEAnL-BOBDEBED FBJTILLABY. 



the inner larger and rounder, and the OTiter smaller and of a triangular 

 shape, which run across the wing; the margin is similarly marked with 

 black dots on a narrow black line, running all round the outside and 

 the base of these wings. The hind wings are marked in a very 

 similar manner, and their base is also black, running into the wing, 

 and forming the inside bordering of the central markings. 



Underneath, the fore wings are much the same as on the upper 

 side, but the ground-colour is more dull, and the black marks, which 

 shew through, are not so large; the tip is of a paler hue than the 

 rest of the wings, and it is divided by a reddish ferruginou^s waved 

 bar, running out below to the edge in a loop. The hind wings are 

 very elegantly marked with reddish ferruginous, buff, and greenish 

 straw-colour, in the way of waved bars, formed by a wide band of 

 the former mottled with the latter, this by one of the greenish straw- 

 colour, and this by one of the latter, the base being also of the greenish 

 straw-colour; the central pale bar has one large spot of silver placed 

 diagonally across it, of an oblong, quadrangular, uneven shape, another 

 inside it of an oblong form, placed upright, wedge-shaped at each end, 

 and another divided in three by the veins of the wing running from 

 near the base of the former to the upper edge of the wing, near the 

 outside corner ; between these three patches and the lower corner is 

 another horizontal one, divided by the red, near its outer and smaller 

 portion, and a row of crescents runs round the edge of the wing, the 

 middle ones silver, followed by a thin reddish line, itself margined by 

 a streak of the greenish straw-colour, which forms the outside margin. 



The caterjiillar is black, with a pale stripe along the sides. The 

 spines are half yellow, and two on the neck are longer than the others, 

 and project forward. 



The chrysalis is of a dull grey colour. 



This species is liable to vary considerably. Mr. Stephens describes 

 one specimen in which the upper surface of the wings was whitish. 

 Another, recorded as a separate species by the name of Thalia, is 

 described as having the wings above pale fulvous, irregularly spotted 

 with black; the front ones, underneath, pale, varied with yellowish 

 and ferruginous towards the tips, with some obsolete black and dusky 

 spots; the hind wings variegated with ferruginous, yellowish, and 

 greenish, with the pupil of the eye very large ; the silvery spot con- 

 tinued to the hind margin, and the usual marginal spots lengthened 

 inwardly, the usual bands obliterated, but the silvery spot at the base 

 somewhat apparent. 



The figures are from specimens in my own collection.
