406 CATALOGUE OF 



pillars were hatched. Being uncertain what plant they fed on, I 

 placed them on slips of different trees ; viz., apple, peach, plum, &c. 

 The young caterpillars were black, with numerous white spines ; as 

 they grew larger, and changed their skins, the spines became covered 

 with a kind of white powder, giving them a very delicate appearance ; 

 added to which, the ground-colour of the body, since the first few 

 days after they were hatched, had become a light green. They always 

 ate their skins after casting them. Day and night they devoured 

 the leaves, and those on the apple-branch grew to an enormous size ; 

 and, on the 12th October, one of these began to prepare for its trans- 

 formation by bending back a large leaf, and inclosing itself in a web, 

 which it completed on the 13th. During the three preceding days 

 it had considerably diminished in size : this I have observed to be 

 the case with many larvae prior to their change. On the 22nd June 

 following the moth came out."

a. $ . Darjeeling. From Messrs. Schlagintweit's Col- 

 lection. 



This species is distinguished from Att. Atlas " by its intensely 

 dark colour, especially on that band bounded by angled and curved, 

 white, denned lines, in which the fenestras occur. This band is of a 

 dark blackish-brown, passing into a rich chestnut-brown above the 

 fenestras of the upper wings and on their posterior margin ; the 

 inner margin of the lower wings is of this red-brown also ; the 

 fenestras are not bounded by a margin of black scales as in Att. Atlas, 

 but by ochreous-yellow squamulation ; the part of the fenestras 

 towards the base of the wings, which in Att. Atlas is curved con- 

 vexly, is in Att. Edwardsii straight ; the fenestra is longer, the white 

 lines on the wings, breaking up the brown so beautifully, are wider, 

 and that on the lower wing is less scalloped than in Att. Atlas ; 

 the margin of the lower wing on the outside has two much-waved 

 lines, the inner is yellow, with thirteen or fourteen undulations, con- 

 tinued on the upper wing till it leaves off where the wing is dilated 

 into the lobe, which gives the wing its hooked-like character ; the 

 lower line is brownish-black, and is straight, except in six places, 

 where the black runs up the nerves triangularly to a point, and 

 meets two of the yellow lobes, which are conjugate."
