Brues, C. T.: New Diptera of the family Phoridae from Paraguay

PHORIDAE FROM PARAGUAY. 439 Hypocera insperata n. sp. Male. Length 2*5 mm. Black, with hyaline wings ; tips of anterior femora, their tibiae and tarsi brownish yellow. Head considerably flat­tened antero-posteriorly and concave behind above and on the sides. In anterior view the front is a little wider than high, and across the top is deeply transversely depressed and then semicircularly elevated into a sharp ridge on the occipital margin as in //. coronata BECKER and //. Johnsoni BRUES; seen from above the concave upper part is slightly over one-third as high as the convex front. Lower row of fron­tal bristles forming a strongly curved line with the median bristles lower, although all bristles in this row are equidistant from one another but closer to the eye margin. Next row of bristles equidistant, the late­ral ones close to the eye margin ; the row curving upward at the center where the bristles are quite close to the lower margin of the occipital depression. Ocelli forming a curved line, each on a tubercle which fits into an emargination of the frontal edge anterior to it ; lateral ocelli separated from the eye only by their own diameter. Occipital bristles as usual ; long, as are the others. Bostocular cilia stout except at the extreme top. Antennae with the third joint large, elongate pyriform, nearly as long as the width of the front, and very densely clothed with fusco-piceous hairs ; arista one-third longer than the third joint, moderately pubescent. Palpi very small, dorso-ventrally flattened, with large stout macrochaetae. Surface of front very sparsely but rather coarsely punctured, each puncture with a fine hair. Thorax pubescent, rather shining, with one pair of small dorsocentral macrochaetae. Scu­tellum transvere, flat, not pubescent ; opaque, twice as wide as long but little curved on its posterior margin ; at each side with a single long bristle about three times as long as the scutellum. Abdomen subshining, its surface bare except along the sides where there is a rather dense band of bristly hairs, weaker posteriorly. Second segment greatly elongated, at the middle ne irly half as long as wide, its poste­rior part and the 3—5 t h segments which are very short, quite distinctly fluted, caused by rounded longitudinal elevations and depressions alter­nating across the abdomen. Sixth segment much narrowed with the hypopygium projecting as a polished black swelling with a few hairs at its tip. Legs very stout, the posterior femora fully one-third as broad as long. Anterior tarsi not, or indistinctly enlarged or flattened, their tibia 1 with a short, stout macrochaeta at its basal third. Middle tibia with three macrochretsp. one externally at the basal fourth, one behind at the basal third, and one externally just before the tip in addition
