and left but mere specks of brownish-grey where they had been. Of course, now in 

 its last stage, I could be sure it was my old acquaintance prunalis, which I had long 

 ago figured and found in this state on elm, honeysuckle, and dogs-mercury ; as if to 

 impress these facts upon me, ere April closed, Mr. C. G. Barrett found several nearly 

 mature larvae on Stacliys sylvatlca and Teiicrium scorodonia, which he kindly for- 

 warded, and reported meeting with more on Lychnis and Marjoram, while here one 

 was found on elder. 



It will suffice to say the larva I had carefully wintered differed in no respect at 

 last from any of those, 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 papillre 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 opaqvie-white 

 euljdorsal 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 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 

 nemoralis and others ; the interior lining was afterwards 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-iDroduced head with prominent eye pieces and more to- 

 wards the tail, the wing covers long, also the antennae and leg cases, the back of the 

 abdomen keeled on the four upper segments and having a row of minute raised dots 

 on either side, the spiracles prominent, the tip furnished with two small curly-topped 

 spines crossing each other near the ends : the colour of the head, thorax, and wing 

 covers pitchy-black and glossy, the abdomen quite dull, black above, brown on the 

 sides and belly and ringed with orange-ochreous at the divisons. — William Buckleb,

Description of the larva of Stilbia anomala. — On the 13th March last I received 

 two very distinct forms of the larva of this insect from Mr. G-. C. Bignell, of Stone- 

 house, Plymouth, to whom they had been sent from Torquay. 



Length, about an inch, and of proportionate bulk; nearly uniformly cylindrical; 

 head rounded and polished, about the same width as the second segment; segmental 

 divisions well defined ; skin soft and smooth, but not glossy. 



Var. I has the ground colour a warm pale chestnut-brown ; head greyish-brown,
