ABROSTOLA. IOQ 



The head and thorax are brown, and the latter is crested. 

 The abdomen is yellowish, with paler incisions, with brown 

 tufts in the middle, and a brown anal tuft. The antennae are 

 brown, and the legs are also brown with lighter rings. The 

 fore-wings are dark grey, suffused with greenish-white in the 

 basal area, and on the tegulse. All three stigmata are present, 

 and are connected by black spaces around the orbicular 

 and claviform stigmata, whilst between the orbicular and 

 reniform stigmata is a blackish space. There are two trans- 

 verse lines, beyond which is a greenish-white band with a 

 slight reddish lustre, whilst at the apex is a black spot bisected

by a pale line. The fringes are bordered with dark brown, 

 slightly dusted with white, and dentated. The hind-wings are 

 brown, rather lighter towards the base, with a slight lunule. 

 The fringes are grey, intersected by two brown lines, and tipped 

 with white. 



The larva feeds on nettles. It is grass-green, and the head 

 is heart-shaped. The three thoracic segments have double 

 white longitudinal streaks on the back and sides, and the 

 succeeding segments have each a dark green mark, pointed 

 behind, and surrounded with white, and similar oblique mark- 

 ings on the sides, the intervening spaces being dotted with 

 white. The legs are green, and above them are green and 

 white longitudinal lines, interrupted in the incisions. Some- 

 times the larva is brown instead of green.
