Mandibles nine toothed, and bearing two barbed processes with a rudimentary spine at the base of the second. Siphon somewhat fusiform, its length about four times its greatest diameter and the anterior respiratory trachea joining the posterior one before reaching the tip of the siphon. Ventral tuft of the anal segment thick, extending along the entire barred area and consisting of numerous branched hairs; dorsal tuft small and composed of only a few hairs. Anal processes fleshy, four, tapering to an obscure point; the tip of the segment bordered by numerous short, recurved, fleshy processes. Corethra lintneri n. sp. PI. 27, fig-. 4 Larvae of this species were taken June 9, 1904, in a cold moun- tain pool near Elizabethtown N. Y., where they were associated with larvae of Culex lazarensis, 0. abserratus, G. cinereoborealis and Eucorethra under- wood i. Several adults emerged June 16 and 17. Description. Female. Antennae slender, sparsely clothed with yellowish hairs, slightly fuscous apically, and each segment with. Wing of female of Corethra lintneri a narrow, basal, fuscous ring. Palpi fuscous, basal segment short, subglobose, second to fourth subequal, rather densely clothed with coarse hairs, the terminal one remarkably distorted. Labial palpi very short, subglobose. Occiput and thorax densely clothed with long, golden yellow scales, the latter with a pair of submedian, naked lines on the anterior two thirds. Pleura semitransparent, yellowish. Abdomen yellowish, irregularly marked with fuscous, specially along the posterior margin of the segments, sparsely clothed with long, yellowish hairs. Dorsal plate of terminal segment rounded, w
