jagged, but often obscured by blaclc dusting ; extreme hind 

 margin dotted with black; cilia pale grey. IVmale (|uite 

 similar, but with simple antennae. 



Underside of all the wings pale silvery grey, abundantly 

 dusted with dark grey ; the lines of the upper side repre- 

 sented by rows of streaks \\\\o\\ nervures. Body grey ; legs 

 pale dull l)rown. 



A little variable in the degree of grey or blackish dusting 

 and red clouding, and in the distinctness of the lines and 

 central rings, but with few or no noticeable local forms. An 

 abnormal specimen in the collection of Mr. S. J. Capper has 

 one wing only — the left foi-e wing — elongated, and its mark- 

 ings so altered that outside the second line the space is filled 

 with black streaks running along nervures almost to the 

 hind margin, and between them blotched with grey and 

 purple-red ; the other three wings are normal. 



On the wing in May. and the beginning of June, and as a 

 partial second generation in July and the beginning of 

 August. 



Larva cylindrical and of nearly uniform width throughout, 

 but the front, and also the last three segments, slightly 

 narrower than the rest; head a little notched on the crown, 

 the lobes rounded, of the same width as the second segment 

 but narrower than the third, pale brown, prettily reticulated 

 and spotted with dark brown, but two stripes of the paler 

 brown colour, running through each lobe, are very conspic- 

 uous ; ground colour of the dorsal surface bright apple-green ; 

 a pale greyish line, finely edged with dark green, forms the 

 dorsal stripe ; the subdorsal lines are of the same colour, but 

 waved throughout their entire length; the whole of the 

 spiracular region, including the space between the subdorsal 

 and ventral regions, is in some specimens entirely white, 

 but in others is very delicately and beautifully marked, at 

 regular intervals, throughout the entire length, with blotches 

 of pink or bright pale purple ; on each side of the fifth to
