AUGUST. 87 



red or ambry hue; upper-parts a shade darker. Body, 

 nearly cylindrical, with a few short hairs round the last 

 joint; top wings slightly broken with veins and faint 

 freckles ; under- wings, thin and uniform, of a light 

 shade of amber, when looked through to the light, a 

 red ambry tinge altogether. This fly was hatched in 

 a water pot. The creeper was put in in May or June, 

 and soon after fastened itself to the side, near the bot- 

 tom, and was hatched on the 18th instant. The pot 

 stood in the garden, and the fly was found floating on 

 the water, alive and perfect, with its empty creeper 

 skin beside it ; and its empty artificial case fast to its 

 original place. The pot was . covered with a piece of 

 gauze, fastened to a wire hoop, to prevent escape. 

 Late black gnat. Out in the day time. 



NOTE FOR AUGUST. The change of temperature 

 of the air begins to tell on insects, this month, and 

 swarms of the tender tribes are swept off; but the 

 waters continue full of creepers ; the constant breeders 

 are unimpaired, and the second swarms of some are 

 turning out more numerous than the first. The ex- 

 tracts for the month are taken from notes made on 

 fishing days and other times of research and observa- 

 tion, during the seasons of many years; which, after 

 numberless close examinations and corrections, formed 

 the foundation of the list of flies. The aquatic flies men- 

 tioned in them this month, are hatching and on the 

 water, more or less, every day. The orange and needle 

 browns are the only ones, of the stone fly class, that 

 remain ; the needles in their varieties and best perfec- 

 tion ; and the orange browns, are excellent for trout
