92 DUKE OF BVBGUNDY FItlTILLAEY. 



of dark blackish brown, the inner one being the most irregular, the 

 indentations of each meeting the next one, forming a kind of mosaic 

 work; the base is entirely of the dark blackish brown colour; the 

 extreme margin is yellowish, intersected at intervals by the outside 

 bar, which is close to it, and immediately inside which is a row of dots 

 in the fulvous part, which is a row of crescents formed by the exten- 

 sions of the next dark bar. The hind wings are nearly entirely of 

 the dark colour, the edge being a row of widely interrupted whitish 

 yellow marks, inside which is a row of fulvous crescents, each with a 

 black triangular-shaped dot within it, and in the centre of the wing 

 three fulvous dots, semicircularly disposed, between which and the base 

 is one other, which may indeed be considered as the upper part of 

 the curve in the shape of a sickle. 



Underneath, the fore wings are of a paler fulvous ground-colour, 

 the outside edge being cream-colour, indented with brown, the centre 

 of the wing being paler than the rest, with two irregular short 

 interrupted rows of large dark brown marks on it, and towards the 

 inner edge and the lower corner, and towards the tip a row of light 

 dots partly following the margin, with one extra one between the row 

 and the tip itself. The hind wings are of a rather darker and richer 

 fulvous, crossed with two irregular waved bars formed of large silvery 

 cream white spots, one near the base and the other about the middle; 

 the latter has some dark markings on its inner edges, and a few more 

 between it and the outside, on the fulvous ground-colour. 



In the female there is a greater extension of the pale colour on the 

 upper surface of the fore wings, and the blackish brown colour is 

 darker. 



The eggs are found solitary or in pairs, on the under side of the 

 leaves of the primrose. They are round, smooth, shining, and of a 

 pale yellowish green colour. 



The caterpillar is of an oval but depressed and elongated shape; 

 the head rounded, heart-shaped, smooth, shining, and of a bright 

 ferruginous colour; the body is covered with rows of tubercles: it is 

 set with feathery hairs. On the hinder part of the back there is a 

 black dot on each joint, and on the sides the like, but the spots less 

 distinct. The general colour is pale olive orange ; underneath, it is 

 whitish; the feet are rusty brown; the claws whitish. It moves very 

 slowly, rolls itself up when disturbed, and remains in that state a long 

 time. Ilubner says that it changes its skin five times before going 

 into the chrysalis state, and that each appearance varies considerably. 



The chrysalis is suspended from the head, and is also kept by a 

 cord round its middle. 



The figure is from one of the specimens in my own cabinet.
