28 LEPIDOPTERA. 



ashy or whitish ; a dark brown irregular stripe runs from the 

 base of the dorsal margin, parallel with the costa, one-third 

 the length of the wing, when it turns with a short curve to 

 the costa ; a second brown stripe, broader and less defined, 

 arising on the costa at nearly two-thirds of its length, half 

 crosses the wing, then makes a bend inward, and turns to 

 the dorsal margin ; the space enclosed between these stripes 

 forms a central baud, more or less clouded, from the margins, 

 with brown, but especially so on the dorsal margin. In it at 

 the end of the discal cell is a small white spot, below which 

 are three thick, longitudinal, straight black streaks, the 

 middle one extending far beyond the other two ; another 

 black, or brown, streak runs from the tip of the wing to the 

 second line, marking off an ovoid apical space of a slightly 

 paler grey. Cilia white, broadly spotted with dark brown. 

 Hind wings dark grey or dark brown-grey faintly dusted 

 with ashy scales ; cilia white with narrow brown dashes. 



Underside greyish brown, with a darker brown transverse 

 band beyond the middle, indistinct in the fore wings, dis- 

 tinct, and followed by a pale band in the hind wings ; cilia 

 white, spotted regularly with black brown. Thorax whitish- 

 brown beneath with a black stripe from the head passing below 

 each wing ; abdomen whitish. 



Not very variable, but English specimens are frequently 

 plain in appearance, portions only of the transverse lines 

 being indicated by ill-defined brown shades, and their general 

 colour is exceptionally brown ; the straight black streaks are 

 very constant. 



On the wing in June, July, and August. 



Larva three inches long, not stout, smooth ; head, dorsal 

 plate, anal flap, horn, legs, and pro-legs, all glossy as though 

 highly varnished, and sprinkled with raised black dots ; seg- 

 ments transversely wrinkled. Dark green with a dark red 

 dorsal stripe edged with yellow ; sub-dorsal stripe yellow or 

 whitish, no oblique stripes ; spiracular stripe yellow, inter- 

 rupted at every segment ; spiracles dark purple, ringed with
