Checkwing. Rather larger and lighter in shades than the 

 spring description. Wings distinctly crossed and tinged 

 to the shoulders with dull pale yellow ; head, top of shoul- 

 ders, and down the back, light yellow green or pale brown 

 olive ; a dark line on the lower edge of each joint of the 

 body, crosses the back and slants on the side to the next 

 joint. Throat, breast, belly, and legs a greenish yellow ; 

 eyes dark. Is a thick, fleshy, fine fly ; one cast its skin in 

 the flybox, which changed it to the red drake. Length, 

 near half an inch ; wings clear, squared, and sparkling, 

 with red and amber towards the shoulders. Legs, head, 

 shoulders and body, light red or ambry foundation, touched 

 on the upper parts with dark red or brown, shewing the 

 slanting lines on the sides. 



Blue drake. Not so large as the spring flies. Length, 

 a quarter and near a sixteenth. Wings fine, and of the blue 

 dun tinge ; top of head, shoulders, and body, dark ashy 

 hue, joints edged with lighter ; belly and breast a blue dun 

 tinge; legs a pale ale transparency, darkest to the feet. 

 Taken from under a large leaf, that grows by the water 

 sides, where many of the aquatic flies take rest after hatch- 

 ing. The blue drake, which hatches in cold weather, 

 appears to cast off three protective skins. After the first 

 she is of a lighter shade, and a smarter fly ; second she is 

 orange ; and the third or last, when in a state of nudity or 

 stripped to the (true) skin, a lemon or straw color. Exam- 

 ined one taken June 5th, at seven p.m. : length three-
