ings, Dr. Leach con-sidered that the May-flies ought to be formed into a separateorder, to which he gave the name of Anisoptera, or imequal-winged insects. The end of the body is furnished with eithertwo or three long and slender filaments ; and by these threecharacters—the mouth, the wings, and the tail—the May-fliesmay be at once distinguished from all other insects. The bestknown species, Ejphemera vulgata, or Common Mat-fly, isshown on Plate VIII. Fig. 1. The transformations of the May-flies are very remarkable,and in some respects almost unique.

These burrowsare double, running horizontally into the mud, and having twooutlets. In fact, they are shaped much like the letter C, sothat the larva can crawl in and out of its hole with perfectease. Its food appears to consist of the decaying vegetablematter of which fresh-water mud is largely composed. In consequence of its hidden dwelling, this larva is not oftenseen even by those who are in the habit of fishing for aquaticinsects. I have found two plans to be successful in its capture.The first is, to detach a large piece of mud, take it carefullyfrom its place, and then examine it under water. The secondplan is, to push a stick into the mud and work it about so asto drive the larvae out of their burrows, and then to move thenet rapidly to and f
