spot. Eventually it tried this experiment " once too often," and, dipping rather 

 too deeply, was unable to rise again on the wing. It began, however, to swim 

 vigorously, and at first made considerable progress, reaching the middle of the 

 pond, but since it then appeared, in spite of its continued efforts, not to be able 

 to make much headway, I waded into the muddy pond, and landed it with the 

 help of my net. My capture proved to be a large female example of Smerinthus 

 ocellatus, but its condition naturally did not admit of its being considered 

 worthy of " cabinet rank " ! I have little doubt that its strange behaviour was 

 due to one or two bright spots on the water, which were visible to me, and were 

 cavised by the reflection of the last rays of light from the sky, exercising over 

 it the same i^ower of attraction which bright artificial lights are well known to 

 possess over this species. — Eustace E. Bankbs, Norden, Corfe Castle : Septem-

Lmnpronia (Incurvaria) tenuicornis, Stn., m Inverness-shire. — On June 15th, 

 1909 — one of the exceedingly few days, during my eight weeks' sojourn in the 

 Scottish Highlands, on which it was possible, even in the most sheltered spots, 

 to collect with a reasonable chance of success — I had the pleasure of taking 

 near Aviemore, Inverness-shire, a beautiful male specimen, in perfect condition, 

 of Lampronia tenuicornis, Stn. It was netted at 6 p.m., whilst on the wing of 

 its own accord in bright sunshine, over a heather-clad bank beside some birch 

 bushes, growing at about 800 feet above sea-level, and it is the only individiial 

 of this very rare and local species that has ever occurred to me. Unfortixnately 

 my efforts to meet with other specimens, both there and elsewhere in the neigh- 

 bourhood, were not attended with success. 



In his original description of " tetiuicornis, n. sp.," in I. B., Lep. Tin., 41 

 (1854), Stainton, who had only seen two individuals, described the head as 

 " pale yellowish," and he used the same expression about it in Man., ii, 297 

 (1859), while Meyrick [HB. Br. Lep., 781 (1895)] says "Head whitish-yellow." 

 Of the four male examples, forming the lamentably short series in my collection, 

 the three older ones have the head either pale ochreous or dingy ochreovis, 

 whilst, in tliat from Aviemore, it is bright orange. This last individvial is, in 

 general, strikingly darker than the other thi'ee, for its silky fore-wings are 

 fuscous-]>lack instead of fuscous, and its hind-wings, thorax, &c., are propor- 

 tionately dark as compared with those of its companions. Probably the imago 

 gi-adually fades in the cabinet, as do so many black or blackish Lepidoptera, but 

 it is also not unlikely that northern specimens are, in nature, more strongly 

 coloured than southern ones. 



Meyrick {loc. cit.) gives the known British distribution of L. tenuicornis as 

 " Kent, Surrey, York to Westmoreland," and I am not aware of the existence of 

 any Scottish examples of it, with the exception of the one recorded above. —

Occurrence of Trichoptihis paludum, Zell., near Woking. — Eai'ly this year 

 my brother and I noticed that the two species of Drosera growing in this district 

 (D. rotundifolia and D. longifolia) were far more abtmdant and well developed 

 than usual, and it occurred to us that there was every probability that Trichop-
