Chrysops amazon n sp. #F Length 9-10.:4 mm.-Front and face gray. The prominent frontal and facial callosities, also cheeks, shining black. Palpi black. Antennre slender. The first and base of third antennal joints reddish, second joint brown and annulate portion of third black. Thorax, shining black; two broad grayish dorsal stripes only perceptible anteriorly. A heavy fulvous pile on pleura. The thorax and th e shining black abdomen sparsely beset with short white hair. Legs black. The four posterior tarsi faintly reddish at base. Wings : the crossband fills out the fourth and fifth posterior cells, thus reaching the posterior margin. (The fifth posterior cell is a shade lighter apically on one specimen). Both basal cells brown with a hyaline dash apically. Anal and axilliary cells, anal angle and alula slightly shaded. A similar shade covers the apex. A halo follows the convex distal border of the cross band quite to the costa, thus separating the crossband from the apical spot which latter vignettes slightly into the second submargined cell. Anal cell closed. This species resembles very closely Chrysops pertinax Williston, but will be distinguished readily by the heavy fulvous pile on pleura, like that of celer, by the crossband which reaches the posterior margin and the difference in the color of antennae ; besides this species has no sign of middorsal triangles on abdomen. Described from four specimens taken at Brown's Mills Junction, N. J.
