 remind me somewhat of the blue-winged oHve, which 

 also puzzled me for a long time. Appearing late in 

 the evening, and only imperfectly visible then, the 

 blue-winged olive has given me many bad quarters 

 of an hour." 



" Besides getting the midge identified, Mr. Mosely 

 was also kind enough to tie me an excellent pattern 

 to imitate it, and I take the liberty of giving the 

 dressing as it appeared in an article on Ch. tentans by 

 him in 'The Field' of September 9th, 191 1. He

 the shoulder and humped over to the neck of the 

 hook, where they should be fastened in and the fly

 way detract from the likeness of the artificial to the 

 natural insect.' 



" I have to confess that the trial of the pattern lacks

 at Blagdon last September, but, as L have already
