Head, excluding the mandibles, a little more than one-fifth longer 

 than wide, the sides moderately convex, the posterior angles widely 

 rounded, the posterior margin shallowly concave, not much narrower 

 in front than behind. Eyes not large, placed just in front of the 

 middle of the sides. Median area of clypeus longer than it is wide 

 across the middle, the anterior margin narrowly excised in the middle, 

 the median carina feeble, not stronger than the lateral striae. Frontal 

 carinae extending back as well-defined ridges almost to the posterior 

 margin and forming the upper boundary of the shallow demiscrobes. 

 Scapes incrassate apically, not reaching the posterior margin of the 

 head ; 2nd-8th joints of the flagellum wider than long, the club 

 longer than the rest of the flagellum. Mandibles finely and closely 

 striate, feebly punctured, armed with 6 or 7 teeth, the posterior four 

 indistinct. 



Thorax constricted at the meso-epinotal suture, the latter distinct 

 but not deep. Shoulders of pronotum rounded ; pronotum convex in 

 front. Pro-mesonotal suture feebly defined. Mesonotum marginate 

 at the sides, the raised margins being continued along the dorsum 

 of the epinotum as far as the base of the spines. Dorsum of 

 epinotum widest at the base, a little longer than wide, joining the 

 declivity in a gentle curve ; the declivity fairly steep, as long as 

 the dorsum. Epinotal spines subacute, directed obliquely upwards, 

 shorter than the interval between their bases, as long as their basal 

 width, and not much longer than the broad episternal teeth. The 

 peduncle of the 1st segment of the petiole is longer or as long as 

 the node, and is rather wide, being almost as wide as the node. 

 The latter is vertically truncate and convex from side to side in 

 front, a little wider than long, the upper surface slopes steeply 

 backwards into a short posterior face. The 2nd node is subglobose, 

 two-thirds wider than, and a little longer than the 1st node. 

 Abdomen oblong, the 1st segment a little longer than wide and 

 forming nearly the whole of the dorsum. Femora only slightly 

 swollen. 



$ . 3 - 5 mm. Black, antennae and legs reddish-brown, the 

 articulations and tarsi paler, mandibles ferruginous. Frontal carinae 

 wider apart than in the ^ • Pronotum transversely rugose ; meso- 

 notum and scutellum strongly and fairly densely longitudinally 

 striate ; dorsum of the epinotum short, oblique, transversely striate 

 at the sides, reticulate-punctate in the middle, shorter than the 

 declivity. Wings tinged with yellow, nervures pale yellow, stigma 

 brownish-yellow. Otherwise like the £> . 



J . 3'4 mm. Black, legs, antennae and mandibles pale brownish-
