Excerpt: ... the mandibles, clypeus, front, vertex, pronotum, gaster, fore coxae, and in a single row on the flexor surf ace of the femora, tibiae, and tarsi. On the gaster the hairs, very conspicuous in certain lights, are present in three or four rows on each of the segments. Pubescence grayish, very fine, dense on the gaster, somewhat sparser on the head, thorax, scapes, and legs. Brownish red; front, upper surface of thorax, petiole, and femora, especially the hind pair, darker or infuscated; gaster black. Described from several specimens taken from two colonies at altitudes of 4,500 and 5,600 ft. in the Huachuca Mountains, Arizona, by Mr. C. R. Biedermann. At first sifjht the species closely resembles a small F. sanguinea rubicunda, especially in the shape of the thorax and petiole and in pilosity, but it differs in having the anterior border of the clypeus projecting and entire, and in the much longer maxillary palpi, much more slender antennae, and the coloration of the head and thorax. 44.
