StiJpnotia salicis on Hackney Marsh. — Towards dusk on July 18th, 1899, I 

 found this insect in abundance round a row of willows opposite the " White Hart," 

 on the east side of Hackney Marsh. At least a couple of hundred I must have seen 

 flitting round the trees, at rest on their stems or on the grass, and not a few drowned 

 in the stream below. There were innumerable pupae too among the leaves, and a 

 fair number of full-grown larvse ; of some two dozen pupae which I brought home 

 Tery nearly half proved to be ichneumoned. — Selwyn Image, 6, Southampton 

 Street, Bloomsbury, W.C. : January 20th, 1900. 



Crambus hortueUus common in Solborn, London. — On several nights at the 

 latter end of June, 1899, I noticed a large number of C. hortueUus flying round the 

 electric lamp which hangs under a glass roof at the Holborn entrance of the " Inns 

 of Court Hotel." On some nights there must have been from a dozen to twenty 

 flying round at one time. Although there are of course any quantity of gas lamps 

 close at hand, I never saw one of these insects at any of them. The nearest grass 

 in the neighbourhood is in Lincoln's Inn Fields ; but this is separated from the 

 entrance to the Hotel by high blocks of buildings at a distance of about a hundred 

 yards.- -Id. 



Aculeate Hymenoptera in North Wales.— T)m'ing visits to Criccieth in 1898 

 and Towyn in 1899 I compiled the following list of Aculeates. The ground worked 

 over was so varied that it cannot be considered a complete one, though I hope it 

 may be useful to future workers in these districts. The distance across the sea 

 between the two localities is about 25 miles. My visit to the former place began 

 on July 14th and ended on August 13th, in the latter I spent the month of July. 

 The capital letters after each species denote the place of capture.
