The position of tliis species cannot 

 be made out from the brief description 

 given.

(J , 9 . Front brown, moderately shining, 

 with ii regularities ; on the lower projecting 

 margin more yellowisli; the narrow orbits 

 and a small stripe in the middle, when 

 seen obliquely, silvery white. Face opaque 

 yellow, with a median brown stripe o^'er 



the carina; cheeks below the eyes brown. 

 Clypeus dark brown, shining; palpi brown, 

 the immediate tip yellowish. Posterior 

 orbits silvery white. The width of the 

 cheeks is equal to about two-thirds the 

 vertical diameter of the eyes. .Antennae 

 red, third joint oval; arista plumose. 

 Mesonotum dark brown O)- reddish brown, 

 opaque, with four whitish stripes, the inner 

 ones continued on the sides of the scutellum, 

 the outer ones punctulate in front; between 

 the inner pair of stripes, there is a median, 

 narrower, less conspicuous one. Pleurae 

 whitish pollinose, and, on the more promi- 

 nent part, in well-preserved specimens, the 

 ground-color shows tlirough in small, round 

 spots. Tegulae white; halteres light yellow. 

 Abdomen more nearly black, opaque, with 

 four rows of silvery white spots, those of 

 the inner rows smaller; oviduct shining

 base of the hind tibiae yellow, and in well- 

 preserved specimens sil\'er\' white: all the

 long bristles arising from tubercles. Wings 

 light brownish yellowish, a little darker near 

 the costa. Length S-:o mm. 



Twenty specimens, Chapada, Brazil, 

 H. H. Smith. I liave no doubt of the 

 identity of this species. Wiedemann, 

 it is true, in liis generic description 

 speaks of a tubercle on the face, but in 

 his specific descriptioti calls the face 

 convex, which applies. Rondani's 

 description differs only in minor details. 

 He mal<es no mention of a facial stripe, 

 and calls the thorax blackish.
