Locality: Horsefly mine—(July 20, 1906. ). /'-' Fig. 15.—Penthetria fragmentum, Handlirsch. A portion 7™° long from the middle of a wing about 11""" in length, the form of which was apparently rather elliptical; its breadth and length were about in the proportion of 1:2-8. The radius is nearly straight, and appears to extend somewhat beyond seven-tenths the length of the wing. The sector arises immediately posterior to the first third of the length of the wing and is distinctly arcuate. The radiomedial cross-vein is situated about the middle of the length of the wing and also midway between the origin and bifurcation of the sector. Quite a distance distally beyond the centre of the wing, the media divides into two apparently widely divergent branches. The moderately curved posterior branch of the cubitus reaches beyond half the length of the wing, while the anterior branch is remarkably straight. The mediocubital cross-vein is situated twice as far above the radiomedial cross-vein as is the latter anterior to the bifurcation of the media. The first anal vein is nearly paraPel with the cubitus. Penthetria nana, sp. nov. Figs. 16 and 17. Locality: Tulameen river, opposite Vermilion cliS—(August 6, 1906. )..
