io8 LLOYD'S NATURAL HISTORY. 



GENUS ABROSTOLA. 

 Abrostola, Ochsenheimer, Schmett. Eur. iv. p. 88 (1816); 



Stephens, 111. Brit. Ent. Haust. iii. p. 96 (1829); Guene'e, 



Spec. Gn. Le'pid. Noct. ii. p. 320 (1852). 

 The species of this genus are of moderate size, with the 

 thorax tufted and the abdomen crested. The fore-wings have 

 no metallic spots or pale lines, and no tooth on the inner 

 margin ; but the stigmata are well-marked, and are bordered 

 with raised scales. The larvae feed on nettles, &c., and are 

 provided with sixteen legs, but the first pair is imperfectly 

 developed, and they loop in walking. There is a hump on the 

 penultimate segment. The pupae are enclosed in cocoons 

 made of silk mixed with moss and earth.
