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

442 CHARLES T. BRUES quite well-developed, but the other frontal bristles very short and weak. Ocelli close together, on a distinct tubercle. Antennae black, with velvety pubescence ; third joint circular in lateral view, but appearing compres­sed when seen from the front. Arista with the two basal joints very stout, bare; third joint strongly pubescent. Palpi black, with numerous short bristly hairs about their tips ; proboscis very short, castaneous. Mesonotum very shining and sparsely clothed with short hairs, with a large, very distinctly impressed, area before the scutellum ; scutellum with two delicate but distinct bristles. Sides of mesonotum lined with decumbent bristly hairs ; one pair of much reduced dorsocentral macro­chaetae. Abdomen bare, subopaque, with the second segment slightly elongated. Legs slender, thinly hairy. Anterior coxae testaceous, their femora and tibiae brownish yellow and their tarsi fuscous; middle legs piceous, lighter on the femora : hind legs piceous. Halteres entirely black. Wings quite distinctly tinged with fuscous, venation blackish brown ; costal vein extending scarcely beyond the middle of the wing, very stout except at base; fringed witb short fine hairs; first vein ending twice as far from the humeral cross-vein as from the tip of the third, and opposite the furcation of the third ; second vein ending midway between the tips of the first and third. Fourth vein evenly but slightly curved, recurved at base and apex ; fifth vein distinctly sinuous, ending far from the fourth as in the European arcuata; sixth vein strongly sinuous; seventh very distinct, nearly straight. A second female differs by its paler legs and pleurae, and fuscous thoracic dorsum. Type from San Bernardino, Paraguay, 1908 ( F IEBRIG ), paratype from Paraguay ( F IEBRIG). The shining front with more distinct bristles and the black hal­teres are the most conspicuous characters distinguishing this species from the European G. arcuata MEIG.
