to be met with in September and October. He ignores ai/tiun- 

 nai'ia altogether. Both Mr Stainton and Newman agree in 

 stating that the larva of dilutata is a general feeder on forest- 

 trees, but Mr Stainton gives September and October as the 

 months for taking the imago. He also says the larva oifiligram- 

 maria feeds upon heather. Newman (quoting Mr Hellins) says 

 sallow. Wood's fig. 639 (erroneously quoted 693 by Dr Staud- 

 inger in his Catalogue) is somewhat like the later and less glossy 

 specimens I take here; but his figure in the Supplement — 1727 

 — which is not quoted by Dr Staudinger at all that I can see, is 

 a fac-simile of some of the early glossy ones. Hubner's figure, 

 188, is like a specimen I possess, which I took on the 29th of 

 September among glossy bluish-grey ones, and is of the green- 

 grey type. Dr Staudinger places a'? before '"'' filigranwiaria ; ''^ 

 and although Herrich Schafter's figures, 194 and 195, are those 

 of a smaller insect, he himself says, " It is perhaps only a small 

 sharply-marked variety of dilutariar On the whole, until it is 

 pi'oved \.o the contrary, I shall hold to the belief that ^^ dilutata,'^ 

 ''^ aittuimiaria!'' and '■'■ filigrammaria''^ are one and the same 

 species. 



Since the above was written, Dr Buchanan White's investiga- 

 tions have made it perfectly clear that aiUiunnaria and dilutata 

 are quite distinct, and \)roh^\Ay Jiligramiua7'ia also. 



Larentia didymata. — A perfect pest. I remember on one 

 occasion boxing a female, and my coat over the pocket was very 

 soon pretty nearly covered with males trying to find out where 

 she had got to. 



L. imiltisti'iga7'ia. — Common. In certain localities any num- 

 ber may be taken at night with a lantern. 



L. casiata. — Common in the woods among Vacciniiun iiiyrtillus ; 

 varies considerably in shade, some specimens being very dark 

 indeed, and might almost be taken for a different insect. 



Emmdcsia alchemillata. — Common in some localities. I am 

 not aware that any species of Galcopsis grows commonly where 

 1 find this insect in most profusion. 



R. albulata. — This insect has of late years appeared commonly 

 among the '* natural hay " near my house. It liad not been 

 observed here previous to 1872. 



E. decolorata was also first observed here in 1872, in one 

 locality only, since which I have seen it i)rctly commonly 

 wherever the campion grows. 



E. cricdata. — I took one specimen on Moncrciffc Hill in
