The i)resent specimen, o( which a figuie is hero given, enlarged six diameters, is a cadis-fly, one of the Neiiroptera. It was found by Dr. Henry .M. Ami, of the theological Survey of Canaila, in the nodules of Green's Creek and sent me f<^r examination. It is of a glistening, dark, smoky brown color, with black veins which are followed with some difficulty, especially where two wings overlap. The clearest and most important part of the neuration is in the ujjper portion of the fore-wing ; but un- fortunately it exhibits in full only the princi- pal cells. These are enough to show that it is a caddis-fly, and that it falls near, if not in the genus Phryganea proper, but it dithers in important points from all the species I have examined in the Museum of Comparative Zoology at Cambridge, containing the large cf)llection of the late Dr. Hagen. The difiference consists jirincipally in the great length of the thyridial area and o( the median cellule, so that the distal termination of the lower cellules is much farther removed from the base of the wing than is that of the upper. It represents a tolerably large species, the preserved fragment being lo mm. long and the probable original length of the fore-wing at least 15 inm. It may bu called Phrypatwa ; I hyvgiinea tjcitu, 11. â¢^â '. IHK MICROSCOPIC M. SOIRBE.
