Described from two specimens received from Mr. Cbtis. Robertson. 
Carlinville, 111. This species, from the elongate legs, lias quite a 
Dexiid asjiect, but is evidently projierly placed in the Tacbinidat, 
for the reason that the frontal bristles descend nearly to the vibrissie, 
and the arista is only short pubescent. 
n. gen. 
Belongs in the Phytointe, not far from Dvepanofflossa, from which 
it differs by the perpendicular face and prominent e|)istoma, also by 
the short terminal tarsal joints. Head, thorax and abdomen differ- 
ing hilt little in width, the head widest. Eyes hare, extending as 
low as the oral margin. Front about one-third width of head ; a 
pair of bristles at each vertical angle, the outer small one directed 
outward and somewhat backward, the long inner one straight up but 
curved backward at tip; the next frontal bristle directed backward, 
the next forward, the rest inward meeting each other; no orbital 
bristles (in % ). Frontal bristles not descending below base of an- 
temne, or but slightly ; sides of face very narrow, bare ; face slightly 
more narrowed than front, perpendicular, oral margin prominent, 
facial ridges bare ; cheeks narrow, bare, with several long bristles 
below tenninated by the vibrisste, which are not decussate, and are 
inserted on the oral margin. Antenuai a little shorter than the face, 
first joint short, second considerably longer ; third joint about three 
times as long as second, hardly widened, nearly straight on front 
border, convex behind ; arista thickened on its jtroximal third, 
clothed with some extremely fine, hardly perceptible pubescence, 
apparently but 2-jointed, tbe fia.sal joint very short. I’roboscis elon- 
gate, bristle-like, nearly twice as long as bight of head, once genicu- 
late, the distal portion curved or bowed, labella not developed ; paljti 
sub-filiform, a little thickened at tip. Scutellum with four lateral 
macrochtette, the apical pair atrophied, very small ; none of them
