bent, smoky transverse line ; cilia pale red. Body and legs 

 red-brown, leg-tufts tinged with red. 



Not very conspicuously variable, but isolated specimens 

 show a tendency to representation of tlie usually absent 

 portions of the ordinary pattern of markings ; one in my 

 own collection has a partial but distinct dull yellow basal 

 line, and a more complete perpendicular and indented first 

 line composed of dusting of the same colour, but the reniform 

 stigma is only indicated by a yellowish margin ; in other 

 examples there is a yellow dot indicating the basal line, 

 or the claviform stigma is faintly suggested in the same 

 colour. Among specimens reared at Hereford by Dr. T. A. 

 Chapman are some in which the purple-red colour is very 

 much blackened, especially in the middle of the wings, Avith 

 the stigmata either bright yellow or very obscure ; and one 

 in which the fore wings are pale brownish-pink with the 

 stigmata yellowish-white and the hind wings white. Those 

 obtained in Durham by Mr. J. Gardner are very dark purple- 

 red with the stigmata obscure ; and Mr. S. J. Capper 

 has one of a dark red-brown without a trace of the stig- 

 mata. 



On the wing at the end of Marcli and in April. 



Larva nearly cylindrical, but the hinder segments are a 

 little thickened and it tapers slightly in front ; head pale 

 green ; body bright green, almost pea-green, abundantly 

 mottled with irregular whitish dots and lines ; dorsal line 

 paler, almost white, slender, edged by deeper green lines ; 

 subdorsal lines waved or undulating, similar, but giving rise 

 in front of each segment to an oblique deeper green dash 

 bending upward, sometimes produced so as to meet at the 

 dorsal line : spiracular line rather slender, undulating, darker 

 green ; incisions of the segments pale green or yellowish ; 

 undersurface, legs and prolegs uniformly pale green. 



Or the ground colour is pale purple-brown abundantly 

 dusted with white ; the dorsal and subdorsal lines pale
