SOME NEW EXOTIC PHORID^. 40.") Aphiochaeta Birói n. sp. (Plate VIII. fig. 4.) Female. Length 1"25 —1*5 mm. Dark brownish varied with black; legs testaceous. The thoracic dorsum is always brown, but the front varies from brown to black and the abdomen is principally brown. Antennae light brown ; palpi pale yellow. Front about as wide as high, grayish pollinose, the ocellar tubercle very distinct and the median impressed line deep. Four proclinate bristles close together; lower angles of the front each with a pair of reclinate bristles inserted rather far apart. Middle row curved strongly downward medially, the inner bristles widely separated, as far from the median line as from the eyemargin. Antennae small, the arista thickly pubescent. Palpi small, weakly bristly below, the apical bristles stronger. Proboscis very short and fleshy. Cheeks with two large downwardly directed macrocliaetae and a row of smaller ones in front. Thoracic dorsum light brown or fuscous, sub-shining, with a single pair of unusually weak dorsocentral macrocliaetae and four equally strong marginal scutellar bristles. The scutellum is sub-triangular, less than two times as wide as long. Abdomen black or piceous, the posterior margins of the segments more of less distinctly margined with whitish yellow. Genitalia pale. Legs short, but not particularly stout. Spur of middle tibia short, less than one-half the length of the basal joint of the tarsus. Posterior femora delicately but distinctly ciliated below with fine yellow hairs, their tibiae bare, without any trace of setulae, but with a fine black line along their hind edge; with a single short, but stout spur. Wings hyaline, the veins dark fuscous ; costal vein reaching considerably beyond the middle of the wing, its cilia exceedingly short and very thickly placed. Third vein forked far from the tip, the second vein meeting the costa two-thirds the way from the tip of the first vein to the tip of the costa. First vein joining the costa three-fourths as far from the humeral crossvein as from the tip of the costa. Fourth vein curved at base and straight at apex ; fifth and sixth slightly bisinuate ; seventh nearly straight, distinct. Halteres pale. Three female specimens, New Guinea (BIRO). TWO from Simbang, Huon Gulf 1899 and the other from Seleo, Berlinhafen 189G. This species is a close relative of A. limbata BRUES from India, but the wings are hyaline and the costal vein is longer, reaching considerably beyond the middle of the wing. Otherwise the two are very much alike.
