between them ; costa narrowly darker ; cilia mixed green and 

 grey. Hind wings short, with the costal margin long, the 

 apex much rounded, and the hind margin moderately so ; 

 smoky-grey, nervures and cilia slightly darker. 



Underside pale smoky-grey, tinged with bronzy- green 

 towards the costa of both fore and hind wings. Thorax, 

 abdomen, and legs of a brilliant green. 



Very little liable to variation, but in preserved specimens 

 the abdomen frequently becomes of a glossy red — probably 

 from some chemical action or from slight damp — indeed the 

 entire insect becomes dark-red if placed in a relaxing vessel, 

 usually recovering its green colour as it dries. In Mr. C. A. 

 Briggs' collection is a specimen having extraordinarily short 

 antennae, in which nevertheless the pectinations are well 

 shown. It was taken at Folkestone. 



On the wing from the middle of June to the middle of July. 



Larva hardly more than half an inch long ; very broad, 

 almost ovate. Head small and flattened, retractile ; segments 

 of the body plump and deeply divided, the second with a 

 smooth, glossy dorsal plate ; raised spots very broad and 

 ovate, occupying much of the surface ; under-surface rather 

 flat ; legs small, placed well underneath. Head and dorsal 

 plate black, the latter tapering in front ; body green with 

 the raised spots or plates light bluish-green ; an indistinct 

 creamy-white or yellowish-white subdorsal line, below which 

 is a broad dark-green stripe ; legs and spiracles black ; prolegs 

 green ; the surface of the body dotted minutely with black, 

 and furnished with short fine blackish bristles. 



When very young it is similarly short and thick, with a 

 retractile black head and a brownish dorsal plate ; body 

 tinted with greenish drab and covered with a short whitish 

 pubescence. As it grows it becomes more green in colour, 

 especially after each moult, fading, before the next, to flesh 

 colour or ochreous-green. After hybernation it is, at first, 

 extremely dark, but after feeding soon becomes of a greener
