 very veiny and much crossed ; when looked through, shew 

 the dark veins on a dim brown ground. Head, shoulders, 

 legs, and body, dark brown. 



Hatches the beginning of this month, and continues 

 through June ; after hatching flies about the water in good 

 numbers, in the day-time.

51ST. RED DUN. 31 Full length, seven-eighths to an inch ;

 September they are more of a cinnamon hue ; some shew 

 more freckle and darker ground.

 hen ; with coppery or amber silk for body, legged with a

The red dun is the largest, and master fly, of the aquatic 



(31) Another member of the numerous family of the Phyganidse ; possibly it is 

 represented by the "Sedge Fly" of Francis, and the "Bank Fly" named in Mr. 

 Aldam's work. My note on Fly 38 applies pretty much the same to this fly in its 

 season.
