the 2nd node are darker, reddish yellow or slightly brownish. Head, 

 thorax and 1st joint of petiole finely and evenly reticulate, 2nd joint 

 of petiole very shallowly punctate, abdomen smooth and shining. 

 Whole body and legs microscopically pubescent. Head one-third 

 longer than wide, sides feebly convex, posterior corners rounded, 

 posterior margin straight. Clypeus produced, projecting over the 

 hind portion of the mandibles. The median area of the clypeus is 

 elongate triangular, raised and produced rather far back between the 

 frontal carinae ; the lateral portions are laminate and bent upwards. 

 The frontal area is small but clearly defined. The frontal carinae 

 short, divergent behind. Mandibles quadridentate, the apical and 

 post-apical teeth large and acute. The scape does not extend back as 

 far as the hind margin of the head ; the 1st joint of the flagellum is 

 two and a half times as long as wide, and as long as the five succeeding 

 joints taken together, the apical joint is four times as long as the 

 penultimate, and nearly as long as the rest of the flagellum less the 

 1st joint; 2nd-9th joints wider than long. Eyes rather prominent, 

 situated well in front of the middle of the sides. Thoi-ax widest in 

 front, not so wide as the head. Pro-mesonotum hardly longer than 

 wide, meso-epinotal suture distinct. The thorax is distinctly con- 

 stricted between the meso- and epinotum. The latter is rather convex 

 lengthwise at the base, and slopes rapidly at the apex to the brow of 

 the concave declivity. Epinotal teeth small, triangular. The 1st 

 joint of the petiole has a short, broad peduncle, the node is narrow, 

 convex above, at the sides and in front, the anterior face almost 

 vertical. The 2nd joint of the petiole is oblong transversely, one-third 

 wider than long, and twice as wide as the 1st, convex above and at 

 the sides. Abdomen oval, the 1st segment distinctly longer than wide, 

 and four times as long as the remaining segments tahen together. 

 Legs moderately long, femora not swollen ; middle and hind tibiae 

 without calcai'ia. 



? (hitherto und escribed?). 2 - 5 mm. Head, thorax and petiole 

 brown, abdomen black, legs, antennae and mandibles yellow, the club 

 of the flagellum infuscate. Head very similar to that of the $ , but 

 a trifle wider. Eyes rather small, very little larger than in the £> . 

 Ocelli small, inconspicuous and sunk a little below the surface. Pro- 

 notum widely exposed at the anterior lateral angles, which are rounded ; 

 the median portion of the pronotum is occluded by the mesonotum, 

 which extends far forwards in the middle. The mesonotum is convex 

 in front, very feebly convex or nearly flat transversely in its posterior 

 half. The scutellum is rather flat, very slightly raised above the level 

 of the metanotum. Dorsum of epinotum wider than long, widest at
