again in the spring; but when they changed their skins the 

 last time they all sickened and died. In a letter which 1 

 received from M. Guenee, a week or two back, he says that 

 about two hundred larvae of" Bonibyx Spartii and the same 

 number of B. Quercus, reared from eggs he received from 

 Cannes, died off in the same way last April. — Henry Double-

Moriality itmong Larrce. — In April last Dr. Wallace most 

 kindly sent me a bountiful supply of the eggs of Saturnia 

 Yaniamai : they hatched during May, and the young larvae 

 appeared at first to be going on favourably, but during the 

 second moult a considerable number of them died, and on 

 visiting them each morning a few others were dead ; the rem- 

 nant were turned out on a small oak in my garden, thinking 

 that perfect exposure to the air might be the means of saving 

 them ; in this, however, I was disappointed, as, during the 

 week ending the 20th of June, every one of them died, and 

 hung down from the oak twigs as flaccid as empty sacks : 

 will any entomologist favour us with his experience in this 

 matter, or, better still, assign a cause for this mortality, and 

 suggest a remedy ? — Edward Newman. 



PieriH Rap(B at the approach of night. — Last evening, 

 July 16th, returning from my engraver's, at 9 p.m., I saw on 

 the bank of the railway a number of white butterflies sipping 

 the lucerne, and flying from flower to flower: 1 believe them 

 to have been all Pieris Rapje.— 7rf. 



Limenitis Syhilla and Apatvra Iris at Ipstvich. — Both 

 these species have been so plentiful that some of our collectors 

 have taken eight or ten dozen of each.— Garrett Garrett. 



New Locality for Sesia Sphegiformis. — Mr. Chappell 



announces, in the * Entomologist's 'Monthlv Magazine ' for 



July, the capture of this rare Sesia, both in Burnt Wood and 



Bishop's Wood, in Stafl'ordshire : the insect rests on low 



plants in the neighbourhood of alder, and one specimen was 



found among birch, far from alder, hovering over a tuft of 



Calluna vulgaris, about 4 o'clock in the afternoon : it is also 



on the wing in the evening, flying raiiidly, with an undulating 

 flight. ^ r> I j-> & 



Lyccena Arion at Painsiiick. — On June 1st I took one 

 specinien of Lycoena Arion on the north-east side of Pains- 

 vvick Hill ; business prevented me visiting the place again in
