Description of the larva of Acidalia ruhricata. —On the 

 13th of August last I received, through the kindness of the 

 Rev. J. Hellins, a young larva of this species. It fed on 

 Polygonum aviculare, growing slowly until the early part of 

 October, when it began to hybernale. On the 15th of that 

 month I took a description as follows : — Length nearly half an 

 inch, slender, but of average Acidalia proportions ; head 

 larger than the second segment, notched on the crown ; body 

 cylindrical, and of .nearly uniform width, but slighly thicken- 

 ing posteriorly ; segmental divisions distinct, each finely 

 ribbed transversely, which gives the skin a rather rough 

 appearance, being also rough to the touch ; general colour 

 grayish brown ; head gray, marked with smoke-colour, 

 medio-dorsal line indistinct to the tenth segment, faint 

 rust-colour; on the remaining posterior segments broad and 

 distinct, dull black. When seen through a lens, however, the 

 faint rust-coloured dorsal line seems to run very narrowly 

 through the broad black of the posterior segments; on each 

 of the other segments the black appears in the shape of two 

 short parallel black marks, one on each side the dorsal line; 

 there are no perceptible subdorsal lines; spiracular lines 

 puckered, lighter than the ground colour : ground colour of 

 the belly similar to the dorsal surface ; it is bordered on each 

 side by a conspicuous dark-smoky subspiracular line. When 

 at rest the food-plant is grasped by the claspers, and the 

 body bent in a curved position, more so than in any other 

 Acidalia larva I have noticed. In this position my larva 

 remained a great part of the winter, but the very severe 

 weather we had appeared to have been too much for it, as I 

 found it dead on examining my hybernating larvae in the
