Calopteryx. 219 



Date. 



In the Xew Forest I ha^■e taken this species on May 7, 

 and also as late as August 18. On the first occasion 

 it was probably just coming on the wing, and on the 

 latter going o\er. These dates ma\' fairly be looked 

 upon as near the limits for the species. Mr. E. A. Fitch, 

 however, reports it as present in hundreds near the 

 source of the Essex and Suffolk Stour, on August 22, 1879, 

 (Entom, 1879, p. 288). 



Habits. 



C. z'iixo flies slowK' in an uncertain fluttering manner, 

 like some of the weak-flving butterflies, along the edges 

 of streams that are overgrown or fringed with bushes. 

 Gorgeous objects the males appear when thus 

 fluttering in the sunshine ; but at rest on a bush, 

 with their wings closed over their back, the\' are not 

 easily seen. When immature, at which time the wings 

 of the male ma\' be without the blue pigment, they 

 ma}' usual!}' be found away from the water (see E. M. M., 

 1 87 1, p. 'Sj and 161 ; 1884, p. 274).
