as tPiird, pointed, with ti discal row and two irregular marginal 

 rows. Male genitalia small and concealed, the tergite overhanging 

 them somewhat as in the less developed species of Uramyia. Wing 

 rather narrow, fourth vein with rounded oblique bend, not concave 

 except near tip, ending but little before apex of wing, beyond the 

 bend almost parallel with hind margin of wing. First posterior cell 

 open, close to costa its sides are almost parallel. Third vein with 

 several hairs at base; hind crossvein joining fourth vein at two- 

 ihii'ds the distance from small to bend. 



Antennae, palpi, proboscis, coxae, femora, tibiae, and sides of first 

 three abdominal segments yellow. Femora not thickened, under side 

 of middle and hind ones with distinct whitish cilia on apical two- 

 thirds, quite long and dense and apparently a good specific character 

 for the male. Front tibia with one bristle on outer hind side, mid 

 tibia with one on outer front, hind tibia with two smallish pairs be- 

 hind, at, and before middle, and a pair subapical ; on the inner flexor 

 side at base some sloping villous hairs, which diminish and dis- 

 appear near middle. Claws and pulvilli moderately elongated. 

 Basal half of abdomen below with long delicate white hairs. 



The female of inajv^Gula is not known, but from what is known 

 of the related species may be expected to have the abdomen short 

 and deep, more or less keeled, the fourth segment narrow and elon- 

 gated forward underneath, so that its discal row of bristles becomes 

 two longitudinal and almost parallel rows, and the genital opening is 

 pushed forward underneath almost or quite to the middle of the 

 venter. This remarkable peculiarity makes the females look differ- 

 ent from the males, but the other characters agree well in both sexes.

One male, the undoubted type, "Novara R. Brasilia." 

 Male. — Closely related to Galodexia vwjuscula. The head is of the 

 same shape, much higher than long in profile, almost circular from 

 in front. The height, length, and width are 53, 32, and 56 in microm- 

 eter units. The eyes are voi y large, both front and face narrower 

 than in most tachinids, and the cheek only one-twentieth of the eye 

 height. The front is very little projecting in profile, even less than 

 in majuscula. It measures the same from the middle to the vertex, 

 0.17 of the head width, the eyes gradually diverging farther down- 

 ward. Ocellars hairlike, proclinate; outer vertical not developed; 

 frontals forming a denser and more homogeneous series than in
