A Week at Wicken. — Monda}', Jul}' Otli, I set out, accom- 

 panied by Mr. Ernest Joy, to this Fen, with the idea that, after 

 the extremely bad weatlier, we shonld be favoured with a fine 

 week, but unfortunately it turned out dull and cold, and some- 

 times very wet. During the first three or four days there, 

 sugaring was the only means by which we could get anything at 

 all ; Leucania impudens and Noctua augur were certainly plentiful, 

 with an occasional Aj^Iecta adrcna, Hadena disslin'dis, H. dentina, 

 and others. Whenever there happened to be a gleam of sunshine, 

 one or two Papillo machaon and Ilyr'ia muricata were to be seen ; but 

 it was not until ni}' friend had left that I came in for an}' success, 

 as on the Friday morning the sun came partially out, lasting for 

 a few hours, enabling me to capture eighteen fine P. machaon, two 

 //. muricata, and several Acidalia immutata. The following day 

 was exactl}' similar, and I took the same species. In the evening 

 of these two last days I went out with Mr. Houghton, of Wicken, 

 and sugared a great many grass-knots, to which insects swarmed, 

 completely covering the knots : L. impudens and N. augur were 

 simply pests, and over a dozen H. advena were taken, among 

 others. Mr. Houghton was perfectly amazed at such numbers, 

 and said he had never before seen a greater abundance of moths 

 at sugar. Scores could be seen flying up against the wind like a 

 swarm of bees. He placed his large lamp and sheet at ray 

 disposal, which attracted the same moths ; also some local 

 species, such as Collix sparsata, Miana arcuosa, Hermhiia 

 cribral'is, kc. Of the latter I obtained a fine series. Before 

 leaving the neighbourhood I managed to find a few Trochilium 

 apiforinis on trunks of poplars, and several larvae of Pap'dio 

 machaon, which were easily fed up. — J. M. Adye ; Somerford

Retarded Emergence of Shetland Lepidoptera. — I was 

 much interested in Mr. Anderson's note {ante, pp. 180, 187) 

 concerning Eupithecia venosata. I had a number of pupse from 

 Mr. Salvage at the same time, but mine all came out between 

 May 20th and June 5th, 1887, not one remaining two years in 

 pupa. On the same occasion, however, I had a number of pupfe 

 of Emmclcsia albulata, also from Shetland, and of these one
