by Fuchs in the " Stettin Ent. Zeitung " under the name of ab. tiigri- 

 cata. Some intermediate forms that lead up to this race are also 

 interesting, while the more ordinary examples tend rather towards the 

 dark-brownish forms. 



The Delamere specimens also are distinctly dark, the prevailing 

 tone being a rich deep brown relieved by an underlying soft grey, 

 which, however, is not very prominent except in the submarginal 

 lines of some of the specimens. In general facies they closely 

 resemble the browner of the Yorkshire forms. 



A unicolorous smoky-black specimen sent to me some time since 

 as a Delamere melanic form of this species should, I think, without 

 doubt be referred to B. genwiaria, and I am not aware that a 

 melanic form of £. repatidata has yet been found in Delamere. 



From North Devon, among a considerable range of the more usual 

 forms, there is one that is, perhaps, the most interesting that occurs 

 in Britain. In it the tendency is for the brown and grey colours 

 which usually give the species its mottley appearance, to separate out 

 into distinct bands, so that in its extreme form we have an almost 

 white insect with a broad dark brown fascia across the middle of its 

 wings and paler brown borders ; while in the intermediate forms the 

 pale ground colour is more or less irrorated with brown, in some cases 

 densely so. This banded form was originally described by Hiibner 

 as a distinct species under the name of conversaria, and a good 

 figure of it was given in the "Entomologist" for 1881 (vol. xiv, 

 PI. I, fig. 14). Although this variety is more frequently met with 

 in Devon and Cornwall than elsewhere, and perhaps there reaches 

 its most extreme forms, it is by no means confined to those two 

 counties. It not infrequently occurs throughout the southern 

 portions of England and in Ireland ; Barrett mentions it from Wales, 

 and South from Durham, but I have been unable to trace any record 

 of it from Scotland, and, indeed, the prevailing Scottish forms do not 

 suggest the likelihood of it occurring there. 



Ireland also furnishes an interesting series ; it includes well-marked 

 forms of var. conversaria, a melanic form with an almost pure white 

 submarginal line, and some dark, mottled grey forms not quite like 

 any that I have seen from elsewhere. The general tone of colour in 

 the Irish specimens is towards the greys rather than the browns, and 

 in the extreme of this particular form the basal third of the fore- 

 wings is densely speckled with dark brownish-grey ; this is followed 

 by a pale grey-white area forming an irregular patch, which extends 

 from just below the costa to the inner margin ; a pale yellowish line 

 passes through it near its outer margin, and this is followed by a sub- 

 marginal whitish line, beyond which the border of the wing is densely 

 speckled like the base ; the hind-wings are pale, like the central area 

 of the fore-wings, to the whitish submarginal line, beyond which they 

 are dark bordered as in the fore-wings (PI. I, fig. 3). 



Series from various parts of the south-east of England, Kent, 

 Sussex, the New Forest, etc., include the largest and most robust
