376 BRITISH LEPIDOPTERAk 



and western parts of the British Islands. The male flies rapidly in the 

 hot sunshine, usually high up (often too high to reach) over the trees and 

 underwood. Bower has, however, found it flying at " sunset," both at 

 Lyndhurst and Chattenden. The female is usually sluggish, and drops 

 like a small lump of clay to the ground from the trees or bushes in 

 which it hides, when one is beating, but Bower has seen the female 

 flying in the afternoon. Horton obtained the species by kicking 

 against the stems of young oaks, in a part free from underwood, and 

 watched the moths half falling and half flying as they were disturbed 

 from the tree-tops ; and James has beaten the imago from hazel. 

 Jones, Fenn, and others, have found the insects in cop. during the 

 day, on grass culms. Bloomfield has caught the species by " dusking," 

 and Burrows on sugared trees (not at the sugar) as late as 11 p.m. 

 Dillon also captured three specimens (2 $ and 1 $ ) flying at dusk, 

 at Clonbrock, and Lowe took specimens at Aigle, at light. Holland 

 has made satisfactory use of a beating-tray for their capture, as 

 many as seven specimens (of both sexes) having fallen victims on 

 June 21st, 1891, at Aldermaston, to this mode of capture.
