NOTES ON COLLECTING. 189 



28. — In June the larvae of Cidaria ailaceata (second brood) feed up 

 well and rapidly on Circaea lutetiana and EpUohium montanniii ; only 

 park of the pup^e emerges in August, the remaining pup* going over 

 until the following May. 



29. — -The imagines of Nascia cUiaiis come freely to light in Wicken 

 Fen from the third week of June onwards when they are usually to be 

 taken on the front of the lamp glass, although some are to be boxed 

 off the sheet. 



30. — Honeycomb affected by larvM' of Achroca iiriMila should be 

 isolated in early June, pupation taking place by the middle of the 

 month among the destroyed cells, the imagines emerging by early July. 



81. — The larvft of Pcrunea hastiana occur in \Mcken Fen almost 

 continuously from June until September in rolled leaves of sallow, 

 without any suggestion of a break to divide the appearances into 

 separate broods.

Help wanted and offered. — Correspondence with a naturalist 

 AND educationalist DESIRED. — Having been for many years interested 

 in the study of lepidoptera, and having amassed a considerable collec- 

 tion, principally for educational purposes, I should be very glad to 

 correspond with some British lepidopterists with a view to exchanging 

 the butterffies and moths of the northern United States (especially 

 of New England) for those of Britain. I am making this appeal not 

 only in my own interests, but at the request of those of my pupils, who 

 are also much interested in the study. We are particularly anxious 

 that a teacher, or a natural history student interested in education, 

 should co-operate with us ; and as I have had considerable experience 

 in this direction, 1 should be pleased to explain in detail the best 

 mode of collecting, preserving, and forwarding specimens. I sincerely 

 trust some educationalist, who is also a naturalist, will interest him- 

 (or her-) self on our behalf. — Wilfred E. L. Todd, Principal, Valley 

 Falls School, Worcester, Mass., U.S.A. March 12th, 1901. 



Butterflies at Cannes. — This note fails by a very little to rival 

 the oft- referred to chapter on " Snakes in Ireland." This season has 

 been the coldest and most inclement known to the oldest visitor. 

 December was all that could be desired, but since then line days have 

 been rare, warm ones almost unknown. In the latter half of February 

 snow and ice were everywhere, and great masses of ice and huge 

 icicles were frequent wherever there was a spray or trickle of water, 

 and ice over an inch thick was often noticed in the Esterels. Even 

 now (March 18th) it is milder, but very wet. On February 17th a 

 newly-emerged ['oran/c iiiri/aiTa was seen, on the 24th a single white 

 butterfly was on the wing. February 25th was the first day that was 

 at all mild, but no butterfly was seen. On the 2()th two I\>/yaiH('is 

 (italanto and one other Vanessid were seen. On the 27th there was 

 some sunshine, and one Pieru ilapliiHce, one Paran/e )in'i/arro, one 

 Chri/s<)iiha)iiis phlacaa, Picris rapac, P. )iapi, Pohpionia eijea, and 

 Pl/raiiit'is atalaiita were seen on the wing near Pegomas. A blank 

 again occurred till March 4th, when Parari/c mnjacra and several 

 Pyraiiiiis atalanta were seen. March 5th was a tolerably fine day, but 

 no butterflies were seen in any numbers, several P, atalanta and P.
