204 LAPPET-MOTH. 



leaf with a serrated border. Hence one of the 

 species was named hy Geoflroy lafeuille morte. The 

 antennas are very short, recurved, and deeply bipec- 

 tinated nearly in a similar manner in both sexes : 

 the palpi very hairy and prolonged into a kind of 

 snout, the second joint longer than the others. 

 Maxilla3 are observable, but they are very minute. 

 The genus includes several European insects, but 

 that figured on the adjoining plate is the only one 

 satisfactorily ascertained to inhabit Britain. The 

 surface of the wings is of a rusty-brown colour 

 varying considerably in shade, the extremity slightly 

 glossed with violet; the upper pair with three 

 oblique waved blackish lines, and a black spot in 

 the centre. The hinder wings are generally un- 

 spotted ; at times, however, they are marked with 

 faint transverse streaks similar to those on the 

 upper pair. The body is of the same colour as the 

 wings ; the stalk of the antennae, the palpi, and the 

 tarsi, of a deep bluish-black. 



The caterpillar is of large size when full grown, 

 sometimes measuring nearly four inches in length, 

 and very variable in colour. The prevailing hue 

 is dusky-grey, inclining to ash-grey, with two blue 

 spots on the neck surrounded with black, and 

 having a black angular mark in the middle. The 

 membranous legs and the under side of the body 

 are ferruginous, the latter spotted with black. Each 

 segment is furnished with a fleshy appendage which 

 hangs from the side, and there is a dorsal tuber- 

 cle on the penultimate joint. (PL xviu. fig. 4.)
