Black, anterior tibiae in front, and a thin band on the base of the 

 hinder pair, obscure testaceous. Thorax above from the scutellum 

 sanguineous. Abdomen smooth, shining, almost bare, head and thorax 

 covered with a sparse grey pile. Wings hyaline, a faint fascia below 

 the stigma ; nervures, costa and stigma black. ? . 



Length 3^ 4 lines. 



The ground colour of the larva is light green, the 

 eye spots black, mouth brownish-black, and there is a 

 black spot over the vertex. A short time after its

 brown claws. As it gets older the white powder 

 develops into a white flaky material, which can be 

 rubbed off ; but this is cast at the last moult, when 

 the larva becomes of a shining green colour. 



They feed on alder from July to October, eating
