Brues, C. T.: Some new exotic Phoridae
some new exotic phor1d.e. 403 is also much farther from the edge of the wing, and the front is pale yellow. Aphiochaeta pauxilla n. sp. (Plate VIII. fig. 2.) Mule. Length 1 mm. Black, including the antennae and halteres. Palpi pale yellow; legs dusky testaceous, hind pair more or less piceous. Front about quadrate, sub-shining and faintly grayish pollinose ; four well-developed proclinate bristles, the two on each side close together but well separated from the pairs oil the opposite side, the two lateral reclinate bristles of the lower row both very near to the lower corner of the front; both middle row and ocellar row straight and regular; ocellar tubercle well-developed and frontal groove distinctly impressed. Antennae small, black, more distinctly ovate than usual, with an almost bare arista. Palpi rather large, with strong bristles. Postocular cilia stout, the cheeks below with a row of about five downwardly directed bristles. Dorsum of thorax subshining, with a single pair of dorsocentral macrochaetae. Scutellum twice as wide as long, with only two bristles. A.bdomen small, black, the segments of equal length. Hypopygium rounded, the projecting lamella small. Legs short and robust, all the joints of the anterior tarsi enlarged; tarsi of other legs slender, the hind metatarsi not over one-half the length of the tibia. Posterior tibiae with a row of fine setulae on the hind margin toward the inner side where they are not very readily seen. Wings clear hyaline, the costal vein reaching to two-fifths the length of the wing, its cilia long and rather sparsely placed, there being only three between the tip of the first vein and the end of the costa. a distance equal to one-half the space between the humeral cross-vein and the tip of the first. First and third veins running close together and curving gradually to meet the costa, furcation of third very close to the tip ; second vein delicate and very weakly developed. Fourth vein slightly but evenly curved; others more nearly straight than usual. Halteres entirely black. One male. Argentine Republic: Lules, October 1905 (V EZÉNYI). This is related to both A. pygmaea ZETT. and A. puxilla MEIG. From the first it may be separated by the black halteres, longer costal vein and less approximated first and third longitudinal veins. From pusillu it differs by the less approximated first and third veins and more widely separated costal bristles, the distinctly flattened anterior tarsi do not occur in either of the two. It is undoubtedly a close relative of these two species of holarctic distribution. I think can be rendily distinguished by these characters aside from the wide geographical separation. 26*
