and covered with fuscous hair at the base ; the eyes entire, projecting beyond the 

 hinder part of the head, which is a little shorter than their diameter ; the occiput 

 slightly convex, rounded. The antennae are moderately stout ; the scape bearing long 

 pale hair, the flagellum with a silky down ; the third and fourth joints are subequal. 

 The thorax deep black, strongly punctured, densely covered with black hair; the 

 pronotum well developed, rounded in front, roundly concave behind ; the scutellum 

 pyramidal, the bottom part strongly punctured and haired, the top smooth and shining, 

 the apex almost perpendicular. The pleurae are densely covered with long pale hair ; the 

 middle of the mesopleurae projects into a large stout tubercle. The median segment is 

 oblique at the top ; the apex rounded, the rest semioblique, bulging out in the middle ; 

 at the base is a broad thick band of pale silvery pubescence ; the sides are strongly 

 punctured. The abdomen is shining, bluish ; the second segment only very slightly, 

 the other segments more thickly and strongly punctured ; the basal segment sparsely 

 covered with pale hair ; the base of the second segment broadly, and that of the third 

 and fourth segments more narrowly, edged with pale pubescence. The first ventral 

 segment is strongly punctured at the base ; the raised central part has on the lateral 

 portions a few punctures, and along its sides is a groove ; the middle is rather blunt, 

 the apex oblique. The second ventral segment bears scattered punctures, and is fringed 

 with white hair along the sides. The other ventral segments are more strongly punc- 

 tured and fringed with pale hairs. The hypopygium is keeled in the middle ; the sides 

 slightly hollowed and punctured. The legs (especially the tibiae and tarsi) are thickly 

 covered with white hair ; the calcaria are white. Wings : the radial cellule projects 

 a little beyond the apex of the third cubital cellule ; the basal abscissa of the radius is 

 a little curved, the apical abscissa elbowed a little below the middle ; the top of the 

 second cubital cellule is shorter than the third ; the first recurrent nervure is received 

 shortly before, the second a little beyond, the middle. The tegulae are broad and shining.

Head very slightly rounded in front, transverse behind ; black, densely covered with 

 long pale hair, punctured ; the eyes large, longer than the space behind them; the 

 mandibles ferruginous before the apex. The antennae black ; the scape punctured, 

 curved, and covered with long stiff white hair ; the flagellum with a dull pile ; the 

 third joint shorter than the fourth. The thorax rufous, punctured, covered with long 

 white hair ; the hair on the mesonotum black, the pleurae finely punctured, the meta- 

 pleurae, and also the median segment, reticulated ; the scutellum flat, the hair at the 

 apex very thick. The abdomen longer than the head and thorax united, rufous, 

 covered with long white hair ; all the segments at the apex thickly fringed with silvery
