220 GENUS ERIOCAMPA. 



nor so sharply pointed at the apex, while the eyes do 

 not reach the base of the mandibles. Selandria again, 

 is easily recognised from Eriocampa by the lanceolate 

 cellule wanting an oblique cross nervure, the colora- 

 tion pattern, too, being different in the two genera. 



The larvae are covered with a white flaky powder, or 

 more usually by a black or olive- coloured resinous 

 exudation. In the latter case they are slug-like in 

 shape, very sluggish and more or less gregarious in 

 habit and feed on the upper surface of the leaf. 



Ten species of the genus as here restricted have 

 been described from the European fauna, one from 

 Northern China, and six from North America, besides 

 the European rosce and limacina.
