piligerous. Smooth and shining. The whole body, including the 

 legs and antennae, clothed with a rather long, erect, pale yellowish 

 pilosity, which is somewhat denser at the margins of the abdominal 

 segments. Pubescence not apparent. Head subquadrate, very 

 convex above, a little wider behind than in front, as long as wide, 

 the sides convex, the posterior angles strongly rounded, the posterior 

 margin almost straight. Median area of clypeus bicarinate, the space 

 between the carinae excavated, the carinae ending in front in two acute 

 teeth, the margin between the carinae concave. A smaller but acute 

 tooth lies outside each of the larger teeth. Mandibles sparsely and 

 coarsely punctured, with three blunt teeth. The scape of the antenna 

 short, extending back a little beyond the posterior third of the head, 

 widened gradually in its apical half ; 1st joint of flagellum about as 

 long as the four following joints taken together ; 2nd and 3rd joints 

 about as long as wide ; 4th-7th slightly wider than long ; the 8th and 

 9th, forming the club, thick and five-sixths as long as the rest of the 

 flagellum. Eyes small, placed well in front of the middle of the sides 

 of the head. Frontal carinae longitudinally striate, slightly divergent 

 behind. A poorly defined frontal area lies behind the prolongation of 

 the clypeus, and is continued into a short frontal sulcus, which ends 

 at about the level of a line joining the eyes. 



Pronotum produced neck-like in front. Pro-mesonotal suture very 

 indistinct dorsally ; sides of pro-mesonotum very convex. Thorax 

 strongly constricted at the meso-epinotal suture, the dorsal profile 

 sloping downwards from the front to the brow of the declivity. 

 Dorsum of epinotum widening posteriorly, passing by a low curve 

 into the vertical declivity, the margins of which are rather prominent. 

 First joint of petiole with a short peduncle; the node thick, squami- 

 form, as high as wide, wider above than below ; the dorsal surface not 

 linear, convex transversely ; the anterior and posterior faces sub- 

 vertical ; the ventral lamella produced in front (under the peduncle) 

 into a small, broad tooth. Second node, seen from above, subglobose ; 

 a little wider than long, and about one-fifth narrower than the 1st 

 node. The abdomen ovate, the basal margin wide, the basal angles 

 rounded, but fairly prominent. 



^ . Minor and minima, 3-1 "8 mm. Entirely pale ochreous ; pilosity 

 shorter and less abundant, the puncturation scantier; head a little 

 more elongate, with the sides less convex. Otherwise like the ^ 

 maxima. 



? . 6 - 5 mm. Head and thorax black ; nodes and abdomen dark 

 brown; legs, antennae and mandibles brownish yellow. Pilosity as 

 in the ^ maxima. Head a little narrower in front than behind ;
