246 THE ENTOMOLOGIST. 



The first perfect butterfly appears on the 91st of June. I am 

 infleV)ted to Mr. Pristo for a supply of this larva, which is 

 little known, although the imago is so familiar to Entomolo- 

 gists. — EfJicard Newi/mn . 



Life-ltislory of Foecilocanipa PopiilL — The imago from 

 which the eggs were procured emerged on the 19th of No- 

 vember. Eggs to the number of 101 were deposited on 

 several subsequent days up to December 1st, and the imago 

 died when it had finished ovipositing. The eggs were 

 hatched on the 19th of April, and the young larvae began to 

 feed immediately on oak and poplar. They changed their 

 skin, as far as I could see, but once up till the Olh of May, 

 when a second change took place. At twenty days' old they 

 were grayish, just as if sprinkled over with the dust of bran, 

 Marlis indistinct, with a reddish flame on each side of the 

 6th segment, veiy pale, and which seemed to die away in a 

 few days. The young larvae now clung by their claspers to 

 the stem of the food-plant ; when one moved, the others 

 usually followed, and appeared to keep close together. On 

 the 16th of May a third change took place, when two con- 

 spicuous red spots appeared on the 2nd segment. The long 

 white fringe hanging over and along each side, together with 

 four large black spots on the belly, were clearly defined. 

 The belly itself quite flat. A fourth change took place on 

 the 23rd of May, and the larva) spun up on June 2nd, 3rd 

 and 4th, when about twelve to fourteen lines in length. —

Lije-liisiory of Boarmia 'perfumaria. — The eggs are laid 

 in July, in clusters of four or five, on the under side of the 

 leaves of Hedera Helix (ivy), more especially — indeed, so far 

 as 1 have ascertained, exclusively — on that large foru) of ivy 

 so common in our gardens, and known as Irish ivy : the 

 young larvae emerge in from ten to fourteen days, according 

 to the temperature, and during the first week feed on the 

 under skin and parenchyma of the leaf, not perforating the 

 leaf, and thus they are kept constantly dry : the female se- 

 lects for oviposition leaves of the current year which have a 

 soft and juicy character, very different from that of last 

 year's leaves ; these, though still in situ, and exhibiting 

 scarcely any sympton)S of decay, are rigid and tough : after 

 tlie expiration of the first week, or ten days at the farthest,
