Gracilaria popidetorum, Z., in Surrey. — Early in April last I was searching 

 for " Micros " on an old fence near Croydon with very little success, as the only 

 species j^resent were Tortricodes hyemana and Chimabacche fagella, until at last I 

 saw a Gracilaria which was quite strange to me Upon a careful examination 

 at home I came to the conclusion that it must be populetorum, a species I had 

 never taken before. This is confirmed by Mr. Bankes who tells me that it is the 

 first specimen he has ever received for identification and also the only modern 

 specimen he has seen. It appears to be an extremely scarce species in the 

 London district, but less so in some other places. Dr. Wood, in a highly instruc- 

 tive article (Ent. Mo. Mag., xxvi, p. 135) on the habits of the larva of this and 

 the two allied species, falconipennella and elongella, remarks that it is quite 

 common certain seasons in some of the Herefordshire Woods, but I am unable to 

 find any record of its captui-e in the immediate neighbourhood of London, 

 either in this Magazine or in the " Entomologist " in the foi-ty volumes ex- 

 amined. — A. Thurnall, Wanstead, Essex : December llth, 1909. 



Evetria sylvestrana -. a correction. — On page 17 of this (January) month's 

 Magazine, Mr. Bankes calls attention to what was undoubtedly a lapsus calami 

 on my part wlien writing on the habits of the above-named species in the 

 November number. I certainly intended Pinus pinea instead of picea. As 

 I am well acquainted with both these trees, I can only suppose that the 

 similarity of tlie two names caused the mistake ; in this case the difference of 

 a single letter quite altered my meaning. In my note on Olethreutes bifasciana 

 on the same page, for " evidently sejjarated localities," read " widely separated 

 localities."^ — ^Id. : January ')th, 1910. 



Some Hymenoptera from the Highlands. — Oiir knowledge of the parasitic 

 Hymenoptera of Scotland, and especially of the Highlands, is practically 

 limited to a few collected about Rannoch by Marshall, at Avieniore by Champion, 

 and in Sutherland by Col. Yerbiiry ; Mr. A. A. Daglish has been good enough 

 to give me a collection from about Glasgow, and Mr. Evans has done some good 

 work in the neighbourhood of Edinburgh. But, as a whole, Scotland has 

 received scant attention in this direction as compared with England, or even 

 Ireland, whence Haliday has pi\t so many species on record. It is interesting 

 to note that all, or nearly all, the Ichneumonidx here taken have been fully 

 described by Holmgren ; " and indeed there seems no reason why any members 

 of the Scandinavian fauna should be strangers to Great Britain, or at least to 

 the Highlands, which are the exact counterpart, if they be not a continuation, 

 of the Norrska Fiellen " (Marshall, Ent. Ann., 1874, p. 123). It may here be 

 noted that, although under such circrunstances, one woiild expect to find the 

 same plants with the same insects feeding upon them, and attacked by the same 

 parasites, yet the pai-asitism is now known to be by no means so exclusive as 

 formerly supposed, and the same parasite may be found in widely differing 

 localities, its range being conterminous with that of its various hosts and not 

 that of any single one of them. 



The following specimens were collected by Mr. Ernest A. Elliott, F.Z.S.,
