138 DUKE OF BURGUNDY FRITILLARV. 



tepn or fifteen lines. The surface is dark brown, t]ie 

 upper wings with three transverse series of irregular 

 ppots of light yellow or straw colour, the outer or 

 marginal row having a black mark in the centre of 

 each spot : the hiiider wings have likewise an iiTegu- 

 lar transverse series of yellow spots, and the margin is 

 simitar to that of the other pair. The under side 

 is much paler than the upper, approaching some- 

 times to orange, the superior wings with several light 

 spots on the disk, interspersed with black streaks, 

 and a series of light spots along the margin, with a 

 small dusky mark in the centre of each ; besides 

 having the margin similar, the hinder wings have 

 two pale bands, composed of continuous oval spots, 

 the outer one edged internally with black. The 

 antennae are white, marked with black above, the 

 club black, tipped with orange. 



According to Hiibner, the caterpillar is long, oval, 

 and depres^:ed, resembling those of the LyccencEy 

 which, from their resemblance to wood-lice (Onisci), 

 are named oniscijbrm. It is of a pale olive-brown 

 colour, with a large black dot on each segment, and 

 the head and legs rusty-red. It feeds on the Cow- 

 slip and Primrose. The butterfly appears to be 

 somewhat local, but it occurs not unfrequently. 

 Cooiiibe and Darenth woods have occasionally af- 

 forded it in abundance, and it has been found in 

 most of the south-eastern counties of England. We 

 liave not heard of its occurrence to the north of Car- 

 li-1.', in the neighbourhood of which it has been taken 

 by Mr Keyshara.
