which is very slender, reddish, and surrounded by paler grey; 

 nervures beyond the middle indicated by interrupted black 

 lines; before the apex are two long reddish streaks, and 

 below them a row of ovate reddish spots parallel with the 

 hind margin ; a dark grey line passing round the apex 

 becomes, upon the hind margin, a series of flat lunules 

 separated by the tips of the nervures ; cilia pale grey, tipped 

 with darker, and continued of a smoky-black and reddish 

 colour, round the anal angle on to the dorsal margin, where 

 it meets the prominent tuft, the dark line continuing across 

 its base. Hind wings semi-transparent white, tinged at the 

 base with yellowish, having the nervures yellowish, and the 

 costal region broadly shaded with grey, which is broken by a 

 commencement of an angulated cross line in accordance with

 grey interrupted by the nervures ; cilia pale grey.

Underside of all the wings whitish ; fore wings grey at the 

 base ; costa and nervures pale brown ; marginal line dark

On the wing from the end of April to the beginning of June. 



Larva cylindrical, stout, smooth, slightly wrinkled at the

 beneath ; dorsal line double, yellow ; on each side of the sixth
