i8 LEPIDOPTERA. 



also being complete on the fore wings and suggested on the 

 hind ; central spot of the hind wings distinct, red-brown ; 

 cilia rather darker ; otherwise similai-. 



Underside rich golden-brown, with a single, more red- 

 brown central transverse stripe which is continuous through 

 all the wings ; occasionally there are faint indications of 

 another nearer the base. Body and legs pale yellow-brown 

 dusted with grey. 



The male is hardly variable to any appreciable extent, but 

 in the female the central stripe of the fore and hind wings 

 is in some specimens almost obliterated, and in others dis- 

 placed in the direction of the first line so as almost to coalesce 

 with it. 



On the wing in June and July and sometimes till the 

 beginning of August. 



Larva over half an inch in length, of uniform bulk, 

 cylindrical, the head horny, reddish-brown, the skin smooth 

 but puckered along the spiracles ; the colour disposed in 

 a multiplicity of fine lines — the dorsal line, which widens in 

 the middle of each segment, is dark green, closely edged with 

 almost black threads ; then a thin white line; then the sub- 

 dorsal line of pale pinkish-brown outlined with darker brown ; 

 then another thin white line ; then three olive-brown lines, 

 the middle one the palest and the lower darkest, partly 

 distinct and partly run together so as to form a stripe just 

 above the spiracles ; spiracular line broad, white, but 

 tinged with yellow in the middle of each segment ; under- 

 surface dirty white, with some oblique dashes and lines of 

 brown. 



When younger the ground colour is pale grey, almost 

 white, the dorsal and supra-spiracular lines aloiost black ; the 

 subdorsal brown ; and the spiracular stripe tinged with 

 yellow. (Rev, J. Hellins.)
