and that the larva feeds in August and September between spun leaves 

 of Populus fvpinnJa. At Aviemore the perfect insect appears about 

 the niiddle of Jiui<\ but has disappeared by about the end of the 

 month : during the past season, when I was closely watching for its 

 emergence, the first example was seen on Jime 15th, and the last on 

 June 28th. I have little doubt that the larva, which seems to be still 

 undescribed, feeds there in August and September, on aspen (Popuhis 

 tremnla), for all the imagines have occurred where aspen and birch 

 bushes grow together in heathy places, none liaving been met with 

 where birch alone was present, even though only a few yards away 

 from their haunts. They may be beaten out of the aspen — and rarely 

 out of the l)ircli — bushes by day, but their flight-time is during the 

 evening, and I have taken them on the wing as early as 4.45 p.m., and 

 as late as 9.45 p.m. Occasionally, about flight-time, odd examples 

 may be disturbed from heather amongst which aspen is growing, 

 having probably just crawled up from below to see whether the 

 weather conditions are sufficiently favourable for taking wing. The 

 males, as a whole, emerge before the females, as is evidenced by the 

 fact that almost all the earlier captures have been referable to the 

 former sex, whereas the later ones have included a modest proportion 

 of females, which are much more rarely met with than the males. The 

 species appears to be very local in the Aviemore district, and my 

 efforts to find it in other spots, liesides those ah'eady alluded to, have 

 met with no success.

A NEW ABEEEATION OF EPHYRA PENDULARIA, L. 

 BY F. C. WOODFORDE, B.A., F.E.S. 



In 1908 I olitained batches of ova from two bred females of 

 Epltyra pendnlarla, L., ab. suhroseata, mihi. One of the females 

 was paired with a bred male, the other with a very worn wild male. 

 No partial emergence took place in August of that year though about 

 eight of the pupae were discovered dead in September with completely 

 developed imagines inside the pupa case. In May and June, 1909, 

 emergence took place, and over thirty perfect imagines were produced. 

 The majority were ab. suhroseata, but eleven were of a coloration I 

 have never seen before. They differ from ab. suhroseata (of which 

 a description aberration may be found in the " Entomologist," vol. 

 XXXV, p. 275) as follows: — The central portion of the fore-wings
