134 THE ENTOMOLOGIST. 



confined to that part of the Pyrenees to which it owes its name. 

 The depth of the ground colour varies from a deep red-brown to 

 a pale yellow ochre shade, the latter being confined to light 

 specimens of the female, and being more usual on the hind than 

 on the fore wing. The variegation of the ground colour into 

 lighter and darker bands is not entirely confined to the female, 

 though its appearance in the male is rare. In the former it is 

 sometimes carried to a surprising extent, so much so that 

 Berg&trasser, in his ' Nomenkiatur,' iii. pi. Ixxviii. fig. 6, depicts 

 it under the name of maturna, and then is not unnaturally sur- 

 prised at its absence of red. The finest specimens I have met 

 with come from Bouveret, at the upper end of the Lake of 

 Geneva, the most beautifully varied on the upper side from 

 Weesen on the Walensee, and from Austria. On the under side 

 there is great variety in the colour and proportion of the bands 

 of the hind wing. There is nearly always a considerable diffe- 

 rence between the colouring of the edging and the lunular 

 portion of the terminal band, and usually, but not always, 

 between the two portions of the central band as well. Some- 

 times the lunulas of the terminal band, sometimes the outer 

 division of the central band, sometimes the light spot and the 

 basal band, or two, or all three of these, are dead-white, or 

 almost as silver as the spots of the Argynnids, sometimes only 

 the spots near the inner margin ; in other cases these bands are 

 of various shades of pale or rich buff ; the dark bands vary 

 equally in colour, they may be of a deep, rich, cinnamon-brown, 

 of a lighter orange-brown, of a dirty yellow-brown, or even of a 

 rich orange containing only a brown tinge. The characteristic 

 spots of the outer band are generally very conspicuous, but 

 occasionally they are somewhat obscured by the darkness of the 

 band, as in some specimens from Bouveret and from Hinter- 

 zarten in the Black Forest ; or they may be ilKmarked, as in 

 some of the very orange-banded specimens from Eclepens in the 

 Jura. There is a specimen in the National Collection labelled 

 " Germania," with the basal band and the light spot almost 

 black, in which the upper side has broad tawny dashes inside the 

 outer line, and a faint tawny suffusion over the fore wings. 

 There are also among those from Germany some of both sexes 

 which seem to me to belong to hritomartis, and of which one 

 regrets not to have more data. 



The specimens of dictijnnoides with which I am acquainted 

 •are somewhat few from which to make generalizations ; they 

 consist only of some ten specimens sent to me by Freiherr v. 

 Hormuzaki, of the few in the National Collection, and of the 

 specimens, again few in number, brought by Mr. Sheldon last 

 year from the Tatra, the latter, however, being in first-rate 

 condition. These, however, vary considerably on the upper side 

 in the extent of their dark suffusion, especially on the hind wing.
