182 ' [January, 



by Mr. Salvage's kindness, been enabled to examine seven specimens. 

 They are — like those previously seen, small — not more than one-half 

 the size of ordinary southern turionella, their fore-wings very dark 

 brown-grey, with leaden transverse lines, and the apical third occupied 

 by a large rust-coloured blotch. Hind-wings grey, with whitish cilia, 

 but not all equally dark, one even having the basal portion decidedly 

 paler. Head and thorax rust-coloured. 



I am simply reiterating a previous statement when I say that 

 these specimens do not in the least represent the true duplana, Hb., 

 in fact, duplana has really nothing to do with the present question, 

 and I merely refer to it in deference to the remarks upon it by 

 Mr. Warren {ante, p. 146). As far as posticana is concerned, the 

 grey-headed, glossy-winged duplana may be set entirely aside. 



Of turionella I reared a considerable number some years ago from 

 pupse found in the unexpanded shoots of Pinus sylvestris in Surrey. 

 Of these I still have about a dozen. These vary in size, most of them 

 being of the usual full size, but one being hardly larger than the 

 Scotch form, and another intermediate. In these Surrey specimens 

 the colouring is bright brownish-grey, with lustrous leaden lines, but 

 the rust-colour is very unequally distributed, some specimens showing 

 it only on the large apical patch, while in others all the darker markings 

 are more or less tinged with it. The ^s have whitish hind- wings, 

 more or Jess tinged with grey towards the hind-margin ; in the $ s 

 these are variably darker in both respects. In some specimens of both 

 sexes the apex of the hind-wings is tinged with rust-colour, in others 

 this is absent. 



Last spring I found, in the same manner, two pupae in this 

 (King's Lynn) neighbourhood. The moths produced — both $ — are 

 quite different in colour, being very strongly tinged with slate- or 

 silvery-grey, except on the rusty patch, which is confined to the apical 

 third. Their hind-wings are unusually white. These Norfolk speci- 

 mens differ almost as much in colour from the brownish or rusty 

 Surrey specimens as they do from the dark brown-grey Scotch form, 

 but they are of the usual full size. 



It thus appears that those from Surrey are variable in colour and 

 size, and in the degree of lightness of the hind-wings ; those from 

 Scotland are fairly constant in their small size, and in their dark fore- 

 wings, but vary in degree of darkness of the hind-wings ; while the 

 Norfolk specimens, with grey fore-wings, have the hinder the lightest. 

 I have examined all very carefully, and with a real anxiety to find
