124 BOTYS HYALINALIS. 



sides of the two segments next the head there is a 

 group of three or four small spine-bearing tubercles ; 

 below the spiracles the abdomen is ornamented with 

 tubercles bearing fewer and shorter bristles than 

 those on the back; the general colour is pale chestnut- 

 brown, the wing-cases and some patches on the back 

 of the front segments darker brown; the bristles, 

 which under a lens look like cocoanut fibre, are light 

 brown ; altogether, this is one of the most singular 

 pupae I have seen. (John Hellins, 6th September, 

 1884; E.M.M., October, 1884, XXI, 99—101.) 



BOTYS VERTICALIS. 



Plate CLIII, fig. 3. 



Towards the end of March (1878) I found a larva a 

 quarter of an inch long in the twisted top of a stinging- 

 nettle ; it was a pale translucent green, with raised 

 spots of opaque darker green and a conspicuous 

 internal vessel of similar darkish green. The plate on 

 the second segment was outlined with blackish at the 

 sides, and the head had dark freckles. 



Through the month of April it continued to grow 

 and to moult. Each time of this operation the spots 

 became less and less distinct, and at length were of 

 the same colour as the skin itself ; after the penulti- 

 mate moult each side of the mouth was blackish and 

 the ocelli black, and a blackish side outline remained 

 to the plate on the second segment, with a dusky sub- 

 dorsal dot on each side of the plate. 



On the 26th of May it moulted for the last time, 

 and no dark outline remained on the plate, only the 

 black mouth and ocelli. By the 31st it had grown to 

 be one inch long and stout in proportion for a Botys 

 larva ; the back was quite bluish-green, the belly, head 

 and legs a much paler yellowish-green, the mouth 

 blackish and the prominent ocelli black, and a black 

 subdorsal dot on each side of the second segment ; a
