together, broad, obtuse at end with a rather thick, subapical, 

 bare black arista, the two basal joints of which are small but 

 distinct. Of cephalic bristles there is only one pair of strong, 

 long, black, parallel or slightly converging, inner verticals; the 

 sides of frons near the base have two or three short, bristly 

 black hairs directed forward ; the rest of the frons is quite bare 

 like the ocellar plate. 



Mesonotum subquadrate, as long as broad, strongly convex, 

 dark yellowish, red, or black, with two approximate, longitudinal 

 brown stripes which are prolonged behind a little over the 

 middle and with- two broader but less distinct stripes on sides 

 not prolonged over the suture in front; pleurae and breast pale 

 yellowish, almost whitish ; humeral calli rounded, very prominent, 

 pale yellowish. Dorsum clothed with short and scanty black 

 hairs; bristles black, long, and strong; three posterior noto- 

 pleurals, approximate ; three to five supra-alars ; one dorsocentral 

 near the scutellum; one very long and strong pteropleural. 

 Scutellum small, convex, rounded, reddish brown above, yellowish 

 on sides and below, with one apical pair of long, diverging 

 black bristles. Postscutellum convex, prominent, dark brownish 

 in the middle; mesophragma narrow, yellowish. Squamae yel- 

 lowish, with black border; halteres yellowish. Abdomen elon- 

 gate, with parallel sides, a little narrower than, and about three 

 times as long as, the thorax; entirely reddish yellow, rather

 transverse band above, which is not prolonged to the sides. 

 Second segment on sides with five or six long, bristly black 

 hairs, the rest with short black hairs ; venter pale yellow. Male 

 genitalia subglobose, yellow, with two brown spots above near 

 the base, shining yellow below and with some short black ap- 

 pendages; in middle there are two long pale yellowish cerci 

 with short black hairs; the last abdominal sternite is in the 

 shape of a prominent, obtuse pale yellowish point, directed for- 

 ward. Ovipositor as long as the abdomen, strongly compressed, 

 with the first segment yellow, the second black. 



Legs long, the four anterior tarsi longer than their tibiae ; hind 

 legs distinctly stronger than the others, with rather thickened 

 femora; the four front pairs and their coxae entirely pale yel- 

 lowish, with the last three tarsal joints blackish ; coxae with some 

 short and pale yellowish hairs. Hind legs with swollen reddish 

 brown coxae ; femora yellowish, with a more or less broad brown 

 ring near the middle; tibiae and tarsi black, the tibiae with a
