rust-red ; apical margins of 1st and 2nd abdominal segments, and 

 sometimes also the posterior half of thorax, slightly tinged with red. 

 Covered all over with a dense, yellowish recumbent pubescence, less 

 abundant, however, on the flagellum. Pilose hairs entirely absent. 

 Exceedingly finely punctate-striate all over, with a few shallow 

 punctures on the sides of the head above the eyes, the petiole and 

 first two segments of the abdomen. The head much narrower 

 across the clypeal region than elsewhere, looks apparently much 

 longer than wide, it is, however only one- sixth longer than its 

 greatest width, i.e. across the eyes. The sides of the head are 

 almost straight, but the eyes project considerably beyond the 

 level of the same ; the posterior angles of the head are rounded, 

 the posterior margin moderately arcuate. The eyes are large and 

 situated at about the middle of the sides. The clypeus is approxi- 

 mately triangular, the posterior margin hardly distinguishable, the 

 anterior margin straight. The frontal carinae are very wide, 

 obtusely angular above the insertion of the antennae (behind which 

 they are a little wider even than in front), nearly parallel, not 

 convergent posteriorly, and extending back to about the level of the 

 middle of the eyes. A shallow depression extends from the posterior 

 margin of the clypeus to about the middle of the vertex. Mandibles 

 triangular, finely rugulose, edentate, the extreme apex truncate. 

 Scape not reaching the occipital margin, incrassate towards the 

 apex ; flagellum about one-third longer than the scape, 1st and 

 2nd joints subequal, a little longer than wide, 3rd-10th joints 

 a little wider than long, apical joint not quite as long as the 9th and 

 10th joints together. 



The dorsum of the thorax and epinotum is flat or only very feebly 

 convex, and is angularly and obtusely delimited from the sides. 

 Pronotum a little wider in front than behind, as long as wide, the 

 anterior angles or shoulders almost obsolete. Pro-mesonotal suture 

 distinct, the meso-epinotal indicated by a slight depression ; the 

 mesonotum is nearly as long as the pronotum, but a trifle narrower. 

 The declivity of the epinotum is almost vertical, angularly emar- 

 ginate above (/^-shaped), and distinctly concave; the lateral margins 

 of the declivity rather tumid, forming at the junction with the 

 dorsum a wide and rounded angle at each side. Node of petiole 

 one-third longer than wide, nearly as wide as the epinotum, the 

 sides almost straight, higher and wider behind than in front, the 

 anterior face very rounded, the posterior face vertical and feebly 

 margined. Ventral lamella of the petiole produced at the extreme 

 base into a rounded projection. Abdomen elongate and narrow,
