THE CLARET DUN 39 



found on slow-running streams. The smoky-blue 

 wings of the sub-imago readily distinguish it 

 from its near relation, the turkey brown, but 

 the imagines are difficult to separate without the 

 microscope. It has been taken in numbers on 

 Lough Arrow, and a specimen was once sent me 

 by Mr. E. A. Ferry from the Itchen. I have 

 taken it myself on the Dever, a small tributary of 

 the Test, and here it is found on a very slow- 

 running portion of the stream above a mill. A 

 figure of the claret dun is given on Plate VII. 



Another species of this genus is LeptophleUa Leto- 

 marginata. It resembles the turkey brown, 

 but the wings are not so heavily shaded. I 

 have found it very plentifully on Loch Tummei 

 during the early part of the season, and have 

 taken a single example on the Test.
