232 LEPIDOPTERA. 



haviug a corona of darker brown freckles beginning on the 

 crown, wliich ai-e continued broadly down the back of each 

 lobe till they approach the ocelli ; on the second segment is 

 a narroAv crescentic velvety black-brown plate, very finely 

 dorsally and subdorsally divided with the ground colour ; 

 this is dark velvety purplish-brown above, pinkish-drab 

 below ; the dorsal pattern is of a top-shape pointing back- 

 ward, dark purplish-brown, and there is a central dorsal 

 black spot at the commencement of each segment ; subdorsal 

 lines slender, pale drab, rather interrupted at the end of 

 each segment, or showing but faintly near the beginning 

 of each, bordered above with a black dash, most conspicuous 

 on segments eight to twelve ; the paler ventral colouring 

 commences along the spiracular region, distinctly, but not 

 abruptly marked in any way ; spiracles black ; on the anal 

 flap is a black-brown velvety plate; skin generally rather 

 rugose. After the last moult the skin is seen to be leathery 

 and rough with wrinkles, the pattern being composed of 

 black freckles upon a deep rosy brownish-red ground ; on 

 the undersurface a few paler or flesh-coloured freckles appear 

 on the reddish ground, without any black ones. 



When just hatched the young larva is of a smoky olive- 

 grey colour, head and doi'sal plate shining dark brown ; usual 

 raised dots black. In ten days dingy brownish olive-green ; 

 a few days later velvety brown with faintly paler dorsal and 

 subdorsal lines, and paler undersurface. (Condensed from 

 Buckler's very full account.) His figures show that after the 

 adult pattern is assumed, but when not half grown, the colour 

 is bright pinkish-brown. August to June or probably to the 

 following June, on Vacciniicm mi/rtillus, Arbutus uva-urd, 

 Empetrum nigi'um, and birch, eating holes in the leaves. 

 But its habits are very peculiar. Mr. T. W. Salvage, who 

 has collected it in several stages in its mountain haunts, 

 writes : " This beautiful species I bred from Mount Sche- 

 hallion in Perthshii-e, from larvae found feeding in (lallcrics 

 under moss about 2500 feet above sea level. I am quite
