THE largest insect belonging to this group, the wings 

 sometimes extending to two inches : the colour of 

 the thorax and anterior wings deep grass-green, the 

 latter traversed by two oblique white lines ; poste- 

 rior wings and abdomen glossy-white; palpi, an- 

 tenna?, and legs tinged with red. 



The caterpillar is very like that last described, 

 but is larger and has a dorsal tubercle on the 

 second segment. It frequents various trees, but 

 seems most partial to the oak. The moth appears 

 about the middle of June. It is a rare insect in 

 this country ; most of the specimens in collections 

 have been obtained from the vicinity of London.
