BRENTHIS PALES, ITS HISTORY AND ITS NAMED FOKMS. 155 



gloss below ; red-brown colour strongly enlarged in all spots, 



bands and dots. West China. 

 var. darja)ia = move fiery- red than i/cneratar, median area entirely 



without markings, black colour reduced at base of forewings and 



abdominal margin of the hindwings. Syr Darja. 

 var. sipora = -Ahove and beneath as arsilache, black markings abundant 



and prominent, spots in middle of forewing thinner and sparser 



in the J , base very black ; in J only the outer marginal area 



of hindwing is not black. N.W. Himalayas. 

 var. 6a>'flZrtf/(rt = sparse markings of both sides (cf. sipora), base hardly 



blackened in ^y , hindwing almost unieolorous, various colours 



weak and diffuse. N.W. Himalayas. 

 In 1913, Fritz Wagner, Beiti\ Lep. Iligebietes, d-c. {Cent. Asia) in 

 Ent. Mitt., Vol. II., p. 114, discussed the form of B. pales sent from 

 that area.

" The individuals obtained from this neighbourhood in great 

 numbers vary extraordinarily in the male sex ; yellow to fiery orange 

 is present in all gradations, as also all intermediates have been cap- 

 tured from strongly marked examples to those before me, which beyond 

 the cross veins and a row of fine black points before the margin of 

 the forewing possess scarcely any further marking. The underside of 

 the hindwing is tolerably contrasted, bright reddish mixed with much 

 yellow. One aberrant ^ with very pale upperside has the underside 

 of the hindwing almost uniform fawn colour, the reddish markings 

 indicated only. The size of the specimens varies between 35-41mm. in 

 the $ and reaches 44mm. in the female sex. 



" While the females of the form now collected by me as typical 

 generator possess a uniform character throughout (dark red brown 

 with distinctly emphasised black markings), the large series ob- 

 tained from the Juldus Gebiete differ so extraordinarily, that on 

 this ground there is a direct suggestion for the necessity of a com- 

 plete separation from the former. Therefore with this further not 

 unimportant distinction I must separate them from generator as var. 

 juldiissica. As characteristics the following can be taken : — 



" The size generally smaller, the undersides of all the wings always 

 in the male, often in the female, distinctly paler, the uppersides duller 

 brown colour in the male sex and the outer part of the marginal area 

 of the females. Most of the female individuals show a blackish green, 

 which compares almost with that of the var. napaea, yet it can vary 

 very nearly to a whitish Isabella-coloured tone; dark red brown females, 

 such as I obtained from localities mentioned previously, appear to be 

 altogether wanting there, at least, there lies before me no example 

 thus coloured. 



" Alpheraky, who mentions this form, and the great variability of 

 the dark females of it already in his collection, ascribed it wrongly to 

 the r/raeca of Stgr., which identification has already been corrected by 

 Staudinger and Wocke in the Catalogue 1901 in so far as they unite 

 the above-mentioned form to generator.
