LEPIDOPTERA. 



nearly straight ; colour dark olive-brown ; basal line a short 

 obscure partial whitish thread from the costa; first line 

 nearly straight, oblique in an unusual direction, placed 

 farther from the base on the costal than on the dorsal 

 margin ; second line almost parallel with it, but placed 

 far back; both are double, darker than the ground colour, 

 but enclosing a slender, almost white thread, and in each 

 the outer dark line is shaded off outwardly ; between them is 

 a parallel dark olive-brown cloudy stripe; subterminal line 

 plentifully angulated and rippled, nearly white, edged outside 

 by a deep shade of the ground colour; orbicular and reni- 

 form stigmata both large, rather dark, each slenderly mar- 

 gined with a fine whitish line ; beyond the middle of the 

 costa are four obscure oblique whiter streaks; cilia long, 

 shining purplish-brown, with a white line along their base. 

 Hind wings broad and large, rather emarginate just below 

 the apex, thence rounded ; pale smoky-brown, slightly glisten- 

 ing, hardly paler at the base ; cilia white. Female accurately 

 similar, except that the body is stouter and has hardly any 

 anal tuft. 



Underside of the fore wings smoke-colour, with the 

 costal and hind-marginal regions broadly glistening smoky- 

 white, cilia reddish-brown. Hind wings smoky-white, 

 dusted along the costal region with pale purplish-grey, and 

 clouded behind with smoke-colour ; central spot small, 

 smoky-black, beyond it is a partial similar cloudy band 

 arising upon the costal margin ; cilia purplish-white at the 

 apex, cloudy-white behind. Body and legs whitish-brown. 



Only a little variable in size, and in the depth of ground- 

 colour and clouding of the fore wings. 



On the wing in July and August. 



Larva moderately stout, tapering to each end ; back 

 slightly angulated, the angles being at the dorsal and 

 subdorsal lines ; skin very thin and semi-transparent ; 

 head small, rounded, and slightly flattened, yellowish-green,
