are much smaller, and do not reach the sides; and the basal ventral segment is 

 distinctly keeled. 



Head, if anything, narrower than the thorax, slightly convex in front and behind ; 

 the eyes hardly projecting beyond the back part of the head, which is straight and does 

 not equal them in length, the edges being rounded ; rather coarsely punctured, covered 

 with golden and silvery pubescence ; black, the front for the greater part ferruginous ; 

 the clypeus dull reddish in the middle, its apex transverse ; the mandibles black, the 

 base ferruginous, the middle deeply grooved. The scape and the two basal joints of 

 the nagellum more or less ferruginous; the third joint twice the length of the fourth. 

 The thorax rounded at the base, the apex with a semioblique slope, the top broadly 

 rounded ; the sides at the basal half straight, the apex broadly incised and with two 

 stout tubercles before the incision. The propleurse at the base punctured ; the meso- 

 and metapleurae impunctate, the apex blackish. The basal segment of the abdomen 

 densely covered with long white hair ; the small basal marks on the second segment 

 are golden, the larger marks yellow ; the third to the fifth segments densely covered 

 with silvery hair; the pygidium with long fulvous hair. The basal ventral segment is 

 testaceous, the others black ; the keel on the apical part of the first segment is distinct, 

 broad, and at the top is clearly separated from the basal region ; the punctures on the 

 second segment are large, those on the other segments fine and close ; the hypopygium 

 is testaceous ; the hair is long and white. The coxa?, femora, and tarsi are obscure 

 ferruginous ; the tibiae are more or less blackish, their spines long, sharp, and also 

 blackish.

Head wider than the thorax, closely punctured ; above bearing long fuscous hairs ; 

 on the face the pubescence is silvery.; the eyes are prominent, not reaching to the top, 

 the head well developed and not narrowed behind them ; at the back, at the sides, 

 there is a projecting tubercle. The scape of the antennae is densely covered with 

 white hair ; the nagellum bears a pale down. The thorax is broad in front, consider- 

 ably narrowed behind, coarsely punctured, and bears long black hair ; the pronotum is 

 transverse, the sides rounded. The mesonotum is excavated deeply in the middle ; at 

 the base are two blunt teeth ; there is a blunt tooth in the deeply incised middle, and 

 at the apex are one blunt and two sharper and longer teeth, followed by another blunt 

 one. The pleurae are excavated, shining, glabrous, impunctate. The median segment 

 is clothed with long white hair. The abdomen is a little broader than the thorax ; 

 the basal segment becomes gradually dilated towards the apex and is confluent with 

 the second, its apex, and also the base of the second segment, smooth, shining, im-
