Hairs ; the antennal tubercles and the mandibles black ; the portion of the head 

 behind the eyes fully half their length. The antennae black ; the scape punctured 

 and sparsely covered with silvery hairs ; the flagellum with a fuscous down ; the third 

 joint distinctly shorter than the fourth. The thorax is more than twice the length of 

 the head ; the pronotum covered with dull silvery pubescence, but not so thickly as to 

 hide the punctures ; the mesonotum coarsely punctured, covered with long black hairs ; 

 the scutellum coarsely punctured, sparsely covered with long black hairs; the median 

 segment with a gradually rounded slope, reticulated, covered with very long fuscous hair. 

 The pro- and mesopleurae are coarsely punctured and covered with long white hair ; the 

 apex of the median segment coarsely reticulated and bearing some long white hair. 

 The petiole becomes gradually dilated to the apex ; black, very coarsely punctured, and 

 covered with long white hairs. The second abdominal segment moderately strongly 

 punctured and covered with black hairs ; its apex and the apex of the third segment 

 fringed with long pale golden hair ; the fourth and following segments entirely black ; 

 the fourth segment coarsely punctured and bearing laterally long black hair; the

 long ferruginous hair, as on the vertex of the head. The pleurae coarsely reticulated 

 and sparsely covered with long black hair. The median segment coarsely reticulated 

 and covered with long black hair ; it has a rounded slope above. The abdomen longer 

 than the head and thorax united, black; from the middle of the second segment 

 covered all over with long ferruginous hair; the petiole narrowed at the base, 

 covered with long black hair ; the base of the second segment coarsely punctured, 

 covered with long, black, somewhat depressed hair. The pygidium is indistinctly 

 keeled in the middle; black, shagreened, almost hidden by the long ferruginous 

 hair of the fifth segment. The basal ventral segment shining, bearing large deep 

 punctures ; the keel only reaching to the middle, becoming gradually raised to its 

 apex, which hardly projects; the apical half of the segment with an oblique slope. 

 The second ventral segment has large widely-separated punctures, and is sparsely covered
