shining, grayish tinged with green. Feeds in a state of 

 nature on Silene otites, but mine did not refuse Lychnis 

 Flos-cuculi. In a few days they began to wander about the 

 breeding-cage, to the sides of which they finally attached 

 themselves, when a single ichneumon emerged from 

 each. Each of these parasites spun its cocoon beside 

 the dying larva : these cocoons, when completed, were very 

 curious, and almost exactly resembled dried husk-covered 

 seeds of some plant. Mr. Bloomfield informs me that a 

 large proportion of the larvae of this insect are infested with 

 this parasite. — Geo. T. Porritt ; Huddersfield, September 2. 



Entomological Notes, Captures, Sfc, 



Aporia Cratcegi at Faversham. — 1 have been much puzzled 

 for several years by finding the pupae of Aporia Crataegi on 

 posts and in the garden, as we have no whitethorn near; but 

 this year I was fortunate enough to find the larvae feeding on 

 the apple trees and the pupae on the trunks. — W, J, Skelton ;

Impregnation of Vanessa Polychloros. — In your life-history 

 of Vanessa Polychloros, in the 'Entomologist' for September, 

 you say impregnation takes place at the spring season, gene- 

 rally in the month of May, and sometimes as early as April. 

 As a general rule, this may be so ; but that exceptions occur 

 is, 1 think, proved by the fact that in the autumn of 1857 

 I had a number of young larvae of this species, as recorded 

 by me in the 'Entomologist's Weekly Intelligencer' of the 

 7th of November, 1857, p. 46. The imago had been caught 

 early in September by a friend of mine, in his hat, six miles 

 from here, and it was placed alive in a box : in two days it 

 had laid over a hundred eggs in regular patches ; in little 

 more than a w^eek they hatched, and fed up on elm to nearly 

 half an inch in length. Having about the same time taken 

 an imago in my summer-house, 1 examined a neighbour's 

 elm tree, and there found on the young suckers a number of 

 larvae precisely like those I had feeding. Thus it was clear 

 that at least two specimens of V. Polychloros had that 

 autumn been impregnated and had deposited their eggs. 

 1 may mention that my larvic did not survive the winter.
