136 BOTYS ASlNALIS. 



dorsal stripe is pale pinkish-yellow, intersected 

 throughout with a dark olive-brown line ; the sub- 

 dorsal stripes are also pinkish-yellow, broadly bordered 

 above with olive-brown ; indeed, this dark colour 

 forms a broad stripe between the dorsal and subdorsal 

 lines ; the spiracles and trapezoidal dots are distinct, 

 black; the ventral surface, legs, and pro-legs greyish- 

 green. The skin is so transparent that the movements 

 of all the muscles can be distinctly seen. 



Feeds on Bubia peregrina ; and in some seasons the 

 larvae are so abundant in the neighbourhood of 

 Bristol that the conspicuous marks made by them on 

 the madder plants form quite a feature in the locality.

BOTYS URTICATA. 



Plate CLIII, fig. 8. 



A small larva was found on the 11th of September, 

 1876, along with four of Ebulea stachydalis on a plant 

 of Stachys sylvatica growing in a ditch. It was nearly 

 three-eighths of an inch long, and about uniform in size 

 throughout, tapering only a little at the twelfth and 

 thirteenth segments; the hind pair of legs was long in 

 proportion, the ventral ones rather long; the segments 

 well cut and tumid beneath. In colour the ground is a 

 lightish green, not bright; the dorsal line is deeper 

 green with a paler whitish-grey line on each side 

 of it, followed by a broad stripe of the same deeper 

 dull green as the dorsal line ; this without harshness 

 is followed by the pale rather greenish-flesh colour of 

 the more translucent belly and legs ; the head is light 

 greenish blotched with black largely on each lobe ; 

 these blotches are partly filled up with black freckles, 

 and a margin of black freckles outlines the side of the 

 cheeks and mouth; on the second segment is a thick, 

 squarish, black spot on each side.
