Within a short time two very interesting species (4-notatus, Ash., and taurulus, Ckll.) have been added to this genus. I have lately received another new species from Mr. Chas. Palm, of New York City, collected in S. W. Utah, which is even more interesting than the two above mentioned. I describe it herewith:

Aphilanthops utahensis, n. sp.—Male: Length, 7.5 mm. Rufous; region of ocelli, mesonotum, metapleura, and fifth and sixth abdominal segments above, blackish. Markings pale lemon-yellow. Head evenly, somewhat sparsely punctate, covered with silvery pubescence, which is very dense on the face, extending over the bases of the mandibles in two pointed tufts. Clypeus with a yellow spot on either side, the median lobe strongly tridentate, the teeth short and blunt. Antennæ with scape yellow; flagellum slightly darker above.
