abdomen, and with the rounded end of it free from 

 the abdomen. At first the pupa is green in colour, 

 irregularly marked with crimson down the back, but 

 by degrees this changes to blackish, and then the 

 whole surface becomes black, but not very shining. 



The moths appeared on the 4th and 14th of June, 

 the larvae having spun up from the 24th to the 30th 

 of May. One larva, from Mrs. Hutchinson, which 

 spun up on the 12th of May, produced the moth on the 

 4th of June. (William Buckler, June, 1875 ; N.B., 

 II, 85, 89, and 107.) 



Plusia pulchrina.

I have once or twice found the larva of this species 

 myself, and in different years have received eggs or 

 larvaB of it from Messrs. J. Gardner, of Hartlepool, 

 and 0. W. Richardson, of Wakefield ; but it was not 

 until 1878 that I had satisfactorily reared it through. 

 The eggs are deposited in June or early in July, and 

 are rather small for the size of the moth, round, but 

 flattened above ; the colour very pale dull yellow, 

 with a few very minute brown dots. They soon 

 hatch, and the newly emerged larvse are greyish- white, 

 indistinctly spotted with black, and the segmental 

 divisions smoke-colour. They feed on dead-nettle 

 {Lamium) and other low plants until autumn, when 

 they commence hibernation, having attained the 

 length of half to five-eighths of an inch. In spring 

 they recommence feeding, and by the end of the first 

 week in May are full-grown, and may be described as 

 follows : 



Length about an inch and a quarter, and stout in 

 proportion ; head glossy, with the lobes rounded, and 

 narrower than the second segment; body cylin- 

 drical, and the segments from fourth to twelfth inclu- 

 sive of nearly uniform size and width ; the thirteenth
