remains fixed to the silk. I mention this substantial difference,

 it for a time, on the 8th found the imago had emerged.) Snellen

 Long, yellowish-green in colour, retaining the dark dorsal stripe seen 

 in the larva. About four days before the perfect insect emerges the 

 wings assume their golden- brown colour, and the eyes become a 

 brilliant crimson, changing in two days to black, and the black- 

 tipped antennae are then plainly visible through the pupa-case 

 (Hawes). 



Time of appeakance. — The species is single- brooded, although its 

 time of appearance is sometimes spread over a considerable period. In 

 its more southern and eastern lowland localities on the Continent it 

 is well out in June and July; as early as May in the Sierra 

 de Ronda ; May and June at Lambessa ; June at Nice and La 

 Turbie ; in the mountains it appears about the middle of July 

 and continues till mid- August, whilst, in Britain, it may appear 

 before the end of June and may continue until the middle of 

 August, depending upon the season. The following actual dates of 

 capture will illustrate this. Captures made abroad, e.g. : — June 21st,
