I.ARENTin.-K—COREMIA. 1 53 



rich light yellow-brown or even to golden-brown, the Latter 

 range of colour being almost universal in specimens from the 

 Shetland Isles, and to a large extent in those from the Orkneys, 

 while in these last the central band is often purple-pink or 

 purjilish-white. In Iceland, where this species is extremely 

 abundant, the vast majority of specimens seem to be of the 

 more ochreous range of colouring. 



On the wing from the end of -lune till August. 



Lak\'A stout, rather tapering in front, and also behind 

 from the elevenlh segment ; back rounded ; sides puckered

 shining, ochreous dotted with darlv brown ; l:)ody pale green 

 or pale yellowish-green, broadly shaded with pink or lilac at 

 the divisions of the segments ; dorsal line pale grey, becom- 

 ing blackish and iuterrnjited from the eighth segment, on

 green, the divisions tinged with lilac; a grey dash lies iu

 brown. ((Jhas. Feun.)

 suffused with pale pur])le-brown.
