334 THE ENTOMOLOGIST. 



Deilephila galii in Yorkshire. — Oa the 12th instant a fine male 

 specimen of the above insect was brought to me. It was taken at rest 

 in a garden in this neighbourhood. I think this is the first time that 

 D. gain has been taken here. — Walter Copley ; Clough Terrace, Sowerby 

 Bridge, August 24, 1889. 



Sbsia ichneumoniformis in Gloucestershire. — I was successful in 

 taking two specimens of 8. ichneumoniformis, one male and one female, at 

 rest on blades of grass in an old quarry on the side of Stinchcombe Hill, 

 near Dursley, on July 22nd. — T. Gr. Mason ; 8, Lansdowne Road, Higher 

 Crurapsall, Manchester, August 14, 1889. 



Zeuzera pyrina. — Records of the capture of Z. pyrina (cescuU) are 

 not very frequent : this may be because the insect is so common that its 

 capture is not thought worth recording, or because it is not very often taken. 

 I have for some years been under the impression that in London the 

 species was common. My past record is as follows : — 1881, July 14th : a 

 worn female found on the ground in the garden of the house I used to live 

 in. 1883, July 15th: a worn female brought to me, found in a neigh- 

 bouring street. 1886, June 80th : a male found at Hackney. July 8th : 

 a male found under a lamp just outside this house. 1887, July 10th : two 

 females emerged from a lilac in my garden. 1888, August 20th : one 

 female emerged from the same tree. 1889, June 28th : a male taken under 

 the lamp already mentioned. In addition to these I have occasionally seen 

 males lying dead inside the windows of public-houses. My captures so far 

 had been sporadic, and had not furnished any very definite indication of 

 the kind of place in which to look for the moth, and of the trees which in 

 London it chiefly affected. On July 5th of the present year the care- 

 taker of an open space in this neighbourhood showed me a male and two 

 females, which he had picked up the previous day under a drooping ash. 

 I found a good many empty pupa-cases sticking out from the tree, and, on 

 exploring the ground thoroughly, was pleased to find a good many infected 

 trees. I3et\veen that date and the 15th I secured about forty specimens, 

 most of them having only just finished drying their wings. The proportion 

 between the sexes was very striking, there being only seven males to 

 thirty-three females. Why this should be T know not, unless it be that 

 the larva of the male, being possibly smaller than that of the female, is 

 able to pupate in the smaller branches at the upper part of the tree, whilst 

 the larger female larva is obliged to work its way down to the larger part 

 of the tree to find room. The moths were found at all heights on the 

 trees, from a few feet above the level of the ground up to about twenty feet, 

 and empty pupa-cases were seen sticking out here and there as high as my 

 light could reach. The enclosure, which is about 2^ acres in extent 

 contains lime, balsam and black poplar, willow, alder, and ash trees, but 

 with the exception of one of the alders, the ash trees were the only ones 

 that were infected, and every one of these was more or less so. I have 

 since looked pretty carefully at the trees in the neighbourhood, and have 

 discovered several infected ash trees and one sycamore. The normal hour 

 of emergence is clearly about 3 to 4 p.m. One specimen was still drying 

 its wings at 5 p.m., and many specimens were found at that hour close to 

 fresh pupa-cases, where none had been at mid-day. The time of year at 

 which the insect should be looked for in normal years appears to be the 

 last week in June and the first fortnight in July. A peculiar feature in
