LASPEYRIA. 191 



with grey, and the tuft of hair at the end of the front tibiae is 

 black above, and whitish beneath. 



The moth is attracted by hghts at Havannah, and rests on 

 the walls of the rooms with its wings flat, the hind-wings being 

 half covered by the fore-wings. 



FAMILY AVENTIID^. 



The single species included in this family is referred by 

 some authors to the Geometrce, and by others to the Deltoides ; 

 but it does not quite agree with either in its characters. The 

 eyes are naked, and ocelli are present. The antenna are 

 simple, and the palpi are ascending, with the second joint 

 broad and triangular, and the terminal joint very short. The 

 abdomen is rather slender, as long as the hind-wings, and 

 the femora are sparsely hairy. The fore-wings are rather 

 short and broad, with the tip hooked, and a deep concavity 

 below ; the hind-wings are rounded. The larva has twelve 

 legs, and is furnished with hairy filaments on the sides ; it is 

 rather short and thick, and feeds on lichens. The pupa is 

 enclosed in a slight cocoon.
