same heat as I apijlied to bring out Ddlephila gdUi in January. I 

 would suggest that Scotch lepidopterists should be pariicularly careful 

 not to throw away pupse which do not emerge the first year at the 

 normal time, — J. W. Tutt. March, 1890. 



DOUBLE-BROODEDNESS OF ACIDALIA EMUTARIA. It may not be 



generally known that the above very local Acidalia is double-brooded, 

 and as the bad nature of the ground frequented by the species is 

 certainly not an incentive to its being systematically worked, it probably 

 accounts for the fact not being more generally known. In the Isle of 

 AV^ight, where I have met with this pretty little " Wave " in considerable 

 numbers, I have found it on the wing about the middle of June, 

 continuing until the end of the first week in July, after which date but 

 occasional single specimens are seen, and these but for a few days 

 longer. After an interval of fully a month from the appearance of the 

 last stragglers of the first brood, the second brood commences to 

 appear, and may be taken until quite the end of August. I have 

 noticed that the early brood produce as a rule much finer specimens 

 than those appearing in August. It is also remarkable how very 

 difficult this species is to beat out, even where known to be abundant, 

 during the day time when the swampy nature of its favourite localities 

 permits such an invasion of its haunts.^ — Albert J. Hodges, 2, High-

EuPERiA FULVAGO AT SHEFFIELD. — I had the pleasure last year of 

 taking a few specimens of this local species, in a very small wood quite 

 close to this town. They were not at all plentiful, but much darker 

 than those from either Sherwood Forest or the neighbourhood of 

 Doncaster. I am very glad, in conjunction with Mr. Batty of this town, 

 to add this species to our ShetKield list. — A. E. Hall, Norbury, Pits-

P/ECiliocampa populi at Light. — Everyone knows how fond this 

 species is of the gas lamps. In a walk round to the lamps in the 

 suburbs of this town on a warm night about the middle of November, 

 one sees it dashing madly against the glass in its endeavours to get 

 inside the lamp ; endeavours which are too often successful, since the 

 trap door used for the purpose of lighting the lamp is generally left 

 open, or if it happens to be shut the chances are the glass is broken 

 somewhere and the moth gets in. When inside, of course it never 

 rests till it has been through the light. If the moth cannot get inside, 

 it rests not on the glass, but on the dark supports or framework of the 

 lamp, where its capture is easy; and in this case it is almost invariably 

 a good specimen. But three out of every four get inside, and ruin 

 themselves. Last November, after an unsatisfactory visit to the street 

 lamps, I thought I would see what another plan would do. I tried two 

 large lamps about 10 feet from the ground, and at the same distance 

 apart, placed in front of a large dark sheet hung up about 15 feet from 

 the lamps. I selected a dark sheet because the moths prefer a dark 

 surface to rest upon. I visited the sheet several times during the 

 evening, and the result was I boxed 20 P. populi and 3 Sphinx cassinea 

 in perfect condition the first night, all quietly at rest on the sheet. 

 After this no more two hours' march round the gas lamps for scorched 



' I have taken both broods repeatedly at Deal. — J.W.T.
