which vary from pale immaculate buff, without suffused under- 

 wing marks of any kind (from Kent), through every shade of 

 buff-brown, ashy gray, to rich-coloured gray-brown, with dis- 

 tinct gray markings (from Wales, Cumberland, Ireland, and 

 Isle of Man). This is the variety capsophila of Boisduval. 



Polia Chi, variety olivacea of Haworlh. 1 have several of 

 this form ; one, given to me by Mr. Allis, is the darkest 

 green I have seen, the body being dark brown ; and one, 

 obtained by purchase at Lees, near Oldham, is dark brown- 

 olive, with the marking very light : this is a most striking 

 instance of change in colour. 



Miselia Oxyacanthge. One rayed variety, and a series of 

 dark almost unicolorous specimens : the latter, principally 

 from the South, give piquancy to my series of ordinary 

 northern specimens.

Life-history of Chauliodus Chcerophyllellus. 

 By Mr. Charles Healy. 



The large brown blotches on the leaves of the con- 

 spicuous umbelliferous plant, Heracleum Sphondylium, caused 

 by the feeding larvae of this species, often arrests our atten- 

 tion during the summer and autumnal months. In order to 

 ascertain the inner or mining life of the larva, it is necessary 

 to examine the plants during the early part of the months of 

 June and August, because at a later period in those months 

 the larvge vacate their mines and become external feeders. 

 The egg is deposited on the under side of the leaf, and 

 when the little larva is born it makes its way into the 

 interior, mining and feeding on the parenchyma of the leaf. 

 Its "frass," at this juvenile period of the larva's life, would 

 appear to be of a somewhat liquid character, and is, I 

 believe, in most cases, contained within the mine. The larva 

 may often then be noticed laying about in its mine, some- 

 times in a reclining and at others in a curled-up posture : its 

 body is while; its head pale brown, with a darker brown spot 

 on each side ; the mouth reddish brown ; and the back of 

 the second segment decorated with a black plate, with a 

 divisional line down its centre ; the dorsal vessel is green
