8 LEPIDOPTERA. 



verse darker brown lines or shades, and near the anal angle 

 a large, ill-defined, roundish brick-red blotch. 



Female pale brownish-grey, yellowish-grey, yellowish- 

 brown, or even pale buff, in many individuals having a rosy 

 or purplish flush ; with markings as in the male, but far 

 paler and less distinct, except in the case of the red patch 

 on the hind wings, which is large and bright. 



Underside extremely plain, greyish, yellowish -grey or 

 yellowish -brown, with the nervures paler, and faint indica- 

 tions of the transverse markings of the upper side. In the 

 hind wings these sometimes become more distinct than 

 above, but there is no indication of the brick-red blotch. 



Variation in this species is usually in the lines already indi- 

 cated — to darker grey markings in the male, and to paler 

 general colour, or excess of rosy bloom, in the female — but 

 in Mr. Sydney Webb's collection is a male having three large 

 pink blotches on the fore wings, one at the base, one near the 

 apex, and the third at the anal angle ; while Mr. C. A. Briggs 

 has a male of the extremely pale buff colour sometimes seen 

 in the female, but with faint indications of grey transverse 

 lines and shadings. At Armagh, in the north of Ireland, the 

 Rev. W. F. Johnson has reared the male having the pink 

 suffusion, and females of an extraordinarily pale yellowish. 

 There is, in addition, a record of the rearing of a specimen 

 wholly of a chocolate colour, and one has been found in 

 Derbyshire devoid of the red blotch of the hind wings. 



Regularly double brooded, appearing in May and June, 

 and again at the end of July and in August. 



Larva stout, firm, rather tapering towards the head, rough 

 with minute raised dots ; head large, green dotted with 

 yellow, triangular, the point upwards, face flattened ; horn on 

 the twelfth segment rough, curved back, yellow, sometimes
