long streaks of excessive faintness just perceptibly forming 

 angles, but these are usually absent; the white crescent 

 already mentioned is the only distinctly visible portion of 

 the second line, and neither is indicated at all in the costal 

 brown area; orbicular stigma suggested by short upright 

 chocolate streaks, between which is a faint fulvous cloud ; 

 base of the reniform only outlined by a slender horizontal 

 chocolate line and three similar dots ; two or three extremely 

 faint whitish dots are just visible on the costal arch, and 

 below the apex are two or three pale longitudinal streaks 

 between the nervures ; parallel with these is, in some indi- 

 viduals, a slender black streak ; extreme hind margin edged 

 by a pale brown line which is preceded by chocolate lunules ; 

 cilia grey dashed with purple-brown. Hind wings short, 

 rounded, smoky brownish-white shading to dark smoky- 

 brown along the hind margin ; nervures dark purple-brown ; 

 cilia white. Female similar, but with a stouter abdomen. 



Underside of the fore wings very dark smoky-grey, almost 

 smoky-black, but the basal portion of the dorsal region pearly- 

 white. Hind wings white, broadly clouded along the costal 

 and apical regions, and narrowly along the hind margin, with 

 smoky-brown ; nervures rather darker. Body pale grey ; legs 

 dull brown with paler tufts, but the front of the tibia3 

 greyish-white with brown lines. 



Hardly variable except that specimens obtained or reared 

 from the salt-marshes of the coast seem to be of a purplish 

 grey, and those from inland localities rather more of a reddish- 

 grey. 



On the wing in June and July. 



Larva elongate, slightly attenuated behind; skin rather 

 polished ; head rounded, bluish-green spotted or dusted with 

 black ; a slight projection on each side of the mouth ; body 

 bright green ; dorsal line broad, yellow ; subdorsal line and 

 another below it pale green ; spiracular line broad, yellow, 

 with the lower half white ; all these lines distinctly edged
