50 LEPIDOPTERA. 



distinct, rather rounded, deep black ; ordinary first and 

 second lines very obscurely and faintly sugsjested by a few 

 isolated dots and streaks without defined form, except that 

 in a clouding of brownish-grey which occupies the dorsal 

 margin they become faintly visible as white lines enclosed 

 between faint brown ones ; cilia black-brown. Uind wings 

 small, rounded behind ; white, often shaded with grey, the 

 dorsal half also dusted with grey, and streaked across the 

 nervures with grey-black ; hind-marginal region shaded with 

 grey, in which runs a white angulated line ; cilia grey dashed 

 with white. Female very similar. 



Underside of the fore wings smoky-white, with a broad 

 smoky-black hind-marginal band, in which is visible a white 

 subterminal line ; discal spot and a costal spot beyond it 

 black. Hind wings white, the central spot black ; a smoky- 

 black band lying broadly along the hind margin is divided 

 by a white cloud. Body white ; legs brown. 



There is some variation in the extent of grey or grey- 

 brown clouding upon all the wings, specimens from western 

 districts having often a faint shade over the greater portion 

 of the white middle area. In rare instances the grey or 

 grey-brown mottling is extended from all the margins so 

 as to cover the middle area, and almost obliterate the white 

 ground ; such specimens were formerly known under the 

 name of E. disparata. 



On the wing in June, July, and August. 



Larva moderately stout, elongated, tapering toward the 

 head ; dingy, dull dark reddish-brown ; dorsal line dingy 

 black, connecting a chain of dull black inverted kite-shaped 

 blotches, which become confluent on the anterior and pos- 

 terior segments ; subdorsal lines dusky, slender, waved, 

 uninterruptedjdarker between the dorsal blotches; spiracular 

 line dirty white, interrupted ; head bordered by a reddish 

 line; undersurface dusky along the edges, pinkish-white in 

 the middle, the central ventral line blackish ; back and side?
