the centre very slightly convex, the anterior margin bare and 

 shining, feebly produced in the middle, and narrowly and shallowly 

 emarginate. Antennae inserted at the base of the clypens, a little 

 nearer to each other than to the eyes ; the second joint of the 

 flagellum fully twice as long as the first, slightly longer than the 

 third, about equal in length to the fourth, but a little shorter than 

 the fifth. Eyes separated on the vertex by a distance equal to 

 the length of the fifth joint of the flagellum. Head subopaque, 

 very minutely and closely punctured ; the front with a longi- 

 tudinal depression on each side, the orbit of the eyes elevated, 

 the anterior ocellus lying in a broad depression, the posterior 

 ocelli indistinct, with a triangular depression behind them. Pro- 

 notum higher in the middle of the posterior mai^gin than at the 

 sides, the middle on a level with the mesonotum, steeply but not 

 vertically sloped anteriorly. Mesonotum microscopically and 

 very closely punctured and opaque, the mesopleura? and scutellum 

 subopaque, the former more distinctly punctured. Median segment 

 scarcely longer than the mesonotum, a little longer than broad, 

 coarsely reticulate, with an ill-defined carina from the base to the 

 apex, sharply but not quite vertically tiamcate posteriorly, the face 

 of the truncation transversely striated, with a median carina. 

 Abdomen shining, microscopically punctiired, the three basal 

 segments with a band of white pubescence on the apical margin, 

 interrupted on the basal segment ; the pygidial area elongate tri- 

 angular, narrowly truncate at the apex. The sides of the median 

 segment are finely obliquely striated. The legs are slender, the 

 anterior tibite unarmed, and the tarsal ungues long. The two re- 

 current nervures are received very close together, before the middle 

 of the second cubital cell. The second cubital cell is at least half 

 as long again on the radial nervure as the third, the second trans- 

 verse cubital nervure is slightly curved inwards, the third is 

 oblique and straight. 



Black ; the mandibles fuscous ; the pubescence on the pygidial 

 area very pale fulvous. "VVings light fusco-hyaline, nervures 

 black, the tegulse fuscous.

$ . Olypeus opaque and very finely punctured at the base, with 

 a delicate carina not reaching the apex, the apex broadly smooth 

 and shining, the margin very broadly rounded, with a very narrow 

 and shallow emargination in the middle. Antenna? rather stout, 

 the second joint of the flagellum twice as long as the first and 

 about one-quarter longer than the third. Head opaque, the 

 front and the base of the clypeus clothed with short fine silver 

 pubescence, which is only visible in certain lights ; the eyes 

 separated on the vertex by a distance equal to one-third more 

 than the length of the first joint of the flagellum. Pronotum very
