epinotum duller and feebly punctured. Node of the petiole longer 

 than wide, convex in front, truncate behind and obtusely pointed 

 above. The ventral lamella in the middle is produced into a sharp 

 spine, pointing backwards. 



Abdomen smooth and shining, apical dorsal segment slightly 

 carinate and ending in a short, sub-acute point. 



Tbe whole body covered with a fine, pale pubescence. Pilosity

Characters. 



$ . Clypeus with the central portion raised, roundly truncate in 

 front and projecting beyond the rest of the clypeus. This raised 

 portion is deeply excavated in the middle, shining, and with two or 

 three longitudinal striae ; the sides of the raised part are also 

 striate. Frontal carinae triangularly dilated in front, slightly 

 divergent behind ; the frontal area, fused with the clypeus, reaches 

 backwards as far as the ends of the frontal carinae, beyond which 

 lies a short, shining depression. 



Mandibles elongate and triangular ; the masticatory margin is long 

 and furnished with numerous small teeth. Plagellum of antennae 

 filiform ; scape arcuate and somewhat flattened at the apex, longer 

 by one-third than the head (excluding the mandibles). Eyes moder- 

 ately large and situated in front of the middle of the sides of the 

 head. Pro-mesonotal suture distinct, meso-epinotal suppressed dor- 

 sally. Thorax widest in front, gradually thinning towards the base. 

 Node of petiole high and rounded ; ventral lamella produced into a 

 broad, triangular tooth. First abdominal segment, at its junction 

 below with the petiole, produced into a blunt tooth ; the segment is 

 vertical in front, and the basal margin above has distinct but obtuse 

 lateral angles. Abdominal constriction feeble. Claws with a small 

 tooth between the base and the middle. 



$ . Winged, larger than the $ ; thorax depressed, with the 

 pronotum largely visible.
