SCOPULA PRUNALIS. 171 



It will suffice to say that the larva I had carefully 

 wintered differed in no respect at last from any of 

 these, and that when full grown it measured seven- 

 eighths of an inch in length, and tapered a little at 

 each end ; the segments plump, especially on the belly, 

 subdivided on the back by a deep wrinkle ; the head 

 of an opaline tint, had the mouth and tips of the 

 papillae brown with dusky traces of former marks, 

 similarly also on the second segment, the colour of 

 the back as far as the spiracular region of a bright 

 and deep transparent green, relieved by two broadish 

 brilliant opaque-white subdorsal stripes ; on these the 

 transparent tubercular warts are partly situated and 

 consequently show half white and half green, each 

 with a whitish hair, the whitish tracheal thread being 

 visible, and along it the minute round cream-coloured 

 spiracles ; below them the pale side and legs faintly 

 tinged with watery translucent greyish-greenish, and 

 like all the rest of the skin brilliantly glittering ; 

 when seen from beneath the alimentary vessels 

 showed green at the segmental divisions. 



To prevent its escape, towards the last this larva 

 was placed in captivity with a few gathered leaves, 

 and amongst them it, in a few hours, cut from the 

 edge of one in a semicircular direction to near the 

 midrib, then turned itself round and commenced a 

 similar cut in the opposite direction about an inch 

 distant from the first, though not going this time so 

 near the midrib ; the edges of the cut portion were 

 then drawn together with silk threads and formed a 

 leafy puparium of the pasty-like form of Agrotera 

 nemoralis and others ; the interior lining was after- 

 wards found to be a very coarse openly-wrought 

 reticulation of silk threads, wherein the pupa lay as 

 in a hammock, its tail attached to one end, where the 

 threads converged. 



The pupa itself, half an inch in length, has a rather 

 slender character, tapering from the thorax to the 

 well-produced head, with prominent eye-pieces, and
