the south of Italy, but I cannot think that the migratory birds 

 which occasionally stay behind and winter in Europe, are in any 

 way influenced by the breadth of sea they have to cross, either in 

 passing over the English Channel or the Mediterranean, but that 

 it arises merely from accidental causes. This is a subject on 

 which I will not take up further time, but proceed to migration 

 as we see it in our own country.,

Eupithecia togata. — I have only seen three specimens of this 

 beautiful species on Moncreiffe Hill, but since the discovery of the 

 habits of the larva, traces of its presence have been noticed in 

 the spruce-fir cones in more than one locality. Mr Herd collect- 

 ed some cones last year which contained larvse, and although most 

 of them went down in the autumn, some are still feeding, he tells 

 me, or at least crawling about among the cones (May 12, 1877). 



Mr Herd found one larva feeding in the pith of a diseased 

 shoot. 



E. 7'ectangiilata. — Common among the apple-trees in my or- 

 chard. Some specimens are brown, with scarcely a tinge of 

 green. 



Lol)ophora hexapterata. — Locally common. First noticed in 

 1873, since which time it has been spreading over the ground. 

 Appears to be attached to white poplar as commonly as to any 

 other variety. 



L. lobulata. — Common above 300 feet. I have never found it, 

 or heard of its being found, on the birches at a lower altitude. 

 This insect does not appear to vary here ; we find none of the 

 darkly-marked specimens which occur in Rannoch. 



Thera variata {obeliscata). — Common among Scots fir. We 

 have a dark and a pale variety here, which Mr Herd believes to 

 be different insects. He tells me the larvae are quite distinct, 

 and that from one form he always breeds the dark insect, and 

 from the other the paler. Possibly before this note is published 

 there may be more to say on the subject.
