£ . 2' 7-3 mm. Brownish yellow, mandibles, antennae, and legs 

 ochreous, abdomen yellowish brown. Thorax very shining, abdomen 

 and head moderately so ; head, scapes, and first two segments of 

 abdomen microscopically punctured, elsewhere impunctate. A short 

 pale sparse pubescence on the limbs and body, a little denser on the 

 abdomen ; the clypeus and apical abdominal segments with a few 

 long pale pilose hairs. Head one-fifth longer tban wide, slightly 

 narrower in front than behind, sides convex, posterior margin almost 

 straight, posterior angles rounded but distinct. Eyes small and 

 black, situated within the anterior fifth of the sides of the head. 

 Mandibles shining, triangular and with a few shallow punctures 

 along the masticatory margin, which is feebly denticulate. Frontal 

 carinae short, separated by a shallow impressed line which reaches 

 back a little beyond the middle of the head. Clypeus short and 

 similar to that of P. Bagusae. The antennae reach back as far as 

 the brow of the declivity, the scape reaching a little beyond the 

 occipital margin. Scape moderately, flagellum more strongly 

 incrassate towards the apex. First joint of flagellum longer than 

 wide, as long as the three following segments taken together ; 2nd- 

 10th joints wider than long, apical joint longer than wide, and a 

 little longer than the two preceding segments together. Thorax 

 narrower than the head. Pronotum a little wider than long, the 

 sides and anterior margin convex, the dorsal surface rather flat. 

 Pro-mesonotal and meso-epinotal sutures sharply defined. Meso- 

 notum half as long as the pronotum, nearly round, and elevated 

 slightly above the level of the latter. Dorsum of epinotum narrow, 

 as long as the pronotum and sloping towards the brow of the 

 declivity ; the latter is oblique. Node of petiole squamiform ; seen 

 from in front it is semicircular above, and wider above the middle 

 line than below it. The anterior face is almost vertical or with only 

 a slight slope from below backwards, and is also feebly convex from 

 side to side. The posterior face is vertical and concave dorso- 

 ventrally. First segment of abdomen as long as the 2nd, both 

 segments almost as long as wide. Intersegmental constriction 

 feeble. 



$ . (Hitherto undescribed.) 3-6 mm. Whole body reddish 

 yellow, mandibles and anterior region of the head castaneous. Eyes 

 black, very large, occupying more than one-quarter of the sides of 

 the head. Pronotum nearly twice as wide as long, and very convex
