270 THE ENTOMOLOGIST. 



moths appeared, having come over the sea. I was informed 

 that they arrived at the break of day, and resembled a fall of 

 snow — they were so numerous. They were also observed 

 many miles at sea. On the day of their arrival they might 

 be seen by hundreds at rest on the buildings facing the sea. 

 I secured many fine specimens. — F. Keery, Harwich. 



Chcerocampa celerio at Brighton. — 1 procured on Octo- 

 ber 4th the larva of the silver-striped hawk-moth {Chcerocampa 

 celerio); it was found in a garden at Brighton. It aj)pears 

 nearly full fed, and no doubt will turn in a few days. Being 

 a very rare species, more especially in the larval slate, I have 

 much pleasure in recording its capture. — C. Brazenor;

Dp:ilephila livornica in Glamorganshire. — A specimen 

 of DeilepJiila livornica was captured at Merthyr-mawr, 

 Bridgend, during the third week in August. It was in good 

 condition, and w^as found on the dining-room window 

 attracted by the light. — G. F. Hampson ; Exeter College,

Notes on Bombyx quercus. — I have often been at a loss 

 to account for the great mortality amongst the larvae of this 

 species. From a partiality to the larvae and images, I have 

 generally collected as many as came in my way when out, 

 but I never yet succeeded in bringing more than a small per- 

 centage of them to the perfect state. Whether this has been 

 from lack of any special treatment 1 am anxious to learn, and 

 probably these notes may call forth a few from others who 

 have had similar experience with this species. During the 

 present year I collected seven larvae o(" B. quercus in different 

 stages of growth, which fed well, and to all appearances 

 maintained perfect health ; they constructed cocoons, and I 

 awaited their emergence, but not one moth came out. A 

 few evenings ago 1 cut the cocoons open ; four of them con- 

 tained dried-up larvae ; the other three had partially undergone 

 metamorphosis ; none of them had been ichneumoned. 

 Again, on referring to my entomological diary, 1 find on May 

 15lh, 1870, 1 collected eight larvae; these all fed well and 

 duly spun cocoons, but no imagos emerged. In 1871 I took 

 four larvae, but obtained no imagos; in 1873 twelve larvae spun, 

 but 1 got no imagos from them ; in 187G they were unusually 

 abundant and early, when between April 2nd and May 14lh 

 I obtained forty-five larvae, the majority of which spun 

 cocoons, the first on May 24th, and tlie last on July 9th ; the 

 first pair of imagos emerged on July 4th, another pair on the
