distinct teeth in front, and 4 indistinct teeth behind. Clypeus cari- 

 nate, distinctly emarginate in the middle. Head quadrangular, as 

 wide behind as long, narrowed in front, nearly straight behind (hardly 

 feebly concave). Eyes decidedly small, consisting of 10-12 facets, but 

 yet larger than in microns. The scape, incrassate from the middle, 

 reaches the posterior fifth of the head ; tln j 2nd-5th joints of the 

 flagelluin are more than three times wider than long. The frontal 

 carinae form exteriorly a deep and wide scrobe for both scape and 

 flagellum, the scrobe bending round behind. Between the groove for 

 the scape and that for the fiagellum, there is a raised and sharp 

 triangle, with its base forwards. The floor of the scrobe is shining 

 and finely reticulate. The eye lies close to the outer margin of the 

 groove for the flagellum, which is obsolete in front. Thorax very wide, 

 short, feebly convex, almost marginate above, with blunt anterior 

 angles. Pro-mesonotal suture absent. Meso-epinotal suture feeble, a 

 suggestion of a metanotum. Epinotal teeth broad, triangular, fairly 

 short and acute ; episternal teeth flat and obtuse. Eirst node of 

 petiole with a very short peduncle, the node two and a half times 

 wider than long, almost vertically truncate in front and behind, the 

 upper surface almost flat or only feebly convex transversely, a little 

 declivous behind, the anterior margin feebly emarginate. Second 

 node nearly three times as wide as long, somewhat wider than, and 

 nearly as high as the 1st, with a straight or even slightly concave 

 anterior face, and a convex posterior face. Abdomen truncate in front- 

 Femora distinctly swollen in the, middle. Head, thorax, and 1st joint 

 of the petiole coarsely and densely, longitudinally rugose, coarsely and 

 closely punctured between the rugae. Second joint of the petiole (the 

 1st also partly) coarsely punctured. The rest smooth, merely very 

 finely and sparsely punctured. The whole body, femora and tibiae 

 closely covered with fairly short, yellow and polyfid hairs. Yellowish- 

 red, abdomen more brownish-yellow. The floor of the coarse punctures 

 appears golden in certain lights. 



" £ . 33 mm. Like the £ . Mesonotum flat above, longitudinally 

 rugose, sharply and coarsely punctured. Nodes somewhat wider, 

 otherwise like the £ . Darker yellowish-red ; a spot on the vertex, the 

 post-scutellum, a part of the mesonotum, and the abdomen brown. 

 Dealated. Pubescence and all else as in the £ .

^ . This differs from the above by the absence of the triangular 

 prominence between the two halves of the antennal scrobe, and by the
