June, iqo4.] BaNKS : NeARCTIC SpIDERS. 109 subtruncate. Forceps as long as the elytra, moderately slender and incurved and armed on the inner side on the basal half with three or four variable sized teeth, the type specimen having four minute teeth on the right branch and two larger and one small one on the left. Legs moderately long ; femora considerably swollen ; tarsi covered, especially below, with fine long hairs, the second segment spatulately pro-longed beneath the third for half its length. Color, light brownish ; antenn?e, front of head, tips of the elytra and the dorsal surface of the abdomen a little darker and the projecting portions of the wings lighter. Length, exclusive of llie forceps, 7 mm.; antenna;, 7 mm.; elytra, 2 mm.; forceps, 2 mm. One male, Bacoor, Prov. Cavite, Luzon, P. I. ; P. L. Stangl, collector. Type. — No. 7885, U. S. National Museum. An additional male from Bacoo, Mindoro, apparently belongs here though the third, fourth and fifth segments of the antennse are somewhat more elongate and the size is greater, the length, exclusive of the forceps, being 8 mm. and the forceps themselves proportion-ately longer, measuring 3.5 mm. This species is apparently very little allied to the only other species of the genus known-'' but according to deBorman's table f it evidently belongs here. Class III, ARACHNIDA. Order II, ARANEIDA. NEW GENERA AND SPECIES OF NEARCTIC SPIDERS. By Nathan Banks, \V.4SHINGTON, D. C. (Plates V and VL) The following pages contain descriptions of some new spiders from the United States, and of a few new genera. These have been found in the course of going over my collection in the preparation of a generic synopsis of our spiders, and a catalogue of the species. Probably another similar paper will follow as the work proceeds. * A. longiforccps Karsch, Berl. Ent. Zeit., XXX, p. 89, pi. 3, f. 7, $ (1886). t Das Tierreich, II, igoo.
