LAKENTID.-E—ASTHENA. 205 



fine brown atoms arising from a cloudy hlack-brown costal 

 spot ; second line similarly obscure, commencing as a cloudy 

 black-brown costal streak, and indicated in the middle, and 

 at the dorsal margin by single or double brown dots and 

 streaks; just beyond it on the costa arises a thicker black 

 cloudy line, rather sinuous and proceeding half-way across 

 the wing, forming the inner edge of a broad orange-tawny 

 blotch dappled with white, which lies across the apical 

 region and almost fills it ; just outside this is the brown 

 irregularly angulatedsubterminal line ; extreme hind margin 

 conspicuously edged with black lunules ; cilia greyish-white 

 with a faint darker intersecting line. Hind wings elongated, 

 greyish-white, crossed by three double smoky-brown faint lines 

 most distinct upon the dorsal margin ; hind margin edged 

 withblack streaks; cilia brownish-white. Female quite similar. 



Underside of the fore wings dull smoky-white ; first, 

 second, and subterminal lines indicated in cloudy black ; 

 hind margin dotted with black. Hind wings white, with 

 faint indications of the transverse lines of the upper side ; 

 hind margin dotted with black. Body and legs pale brown. 



r)nly a little variable in the distinctness or alisence of the 

 transverse delicate lines, and in the depth and richness of 

 the apical blotch. 



On the wing sometimes at the end of ^fay, and till -Tuly, 

 and even the beginning of August — apparently only the 

 extended emergence of a single generation. 



Larva slender, but nearly cylindrical, ta]iering a little 

 behind ; skin soft and rather glossy ; wrinkled at the 

 divisions, puckered at the sides, and set with a few hairs ; 

 head smaller than the second segment, green, with a streak 

 of crim.son-brown on each lobe ; general colour of the Ijack 

 and sides pale greenish-yellow, the uudersurface slightly 

 greener ; collar shining ; on the second to the fourth seg- 

 ments is a long oval dorsal patch of pinkish or crimson- 

 brown, widest on the third, and ending in a blunt point at
