shining. Head finely and closely punctured, 1st and 2nd abdominal 

 segments a little more coarsely punctured, thorax nearly impunc- 

 tate. Covered all over with a fine and close grey pubescence, and 

 with a few scattered and rather short pilose hairs on the thorax 

 and abdomen. Head, excluding the mandibles, rectangular, and 

 one-fifth longer than wide ; the posterior angles widely rounded, the 

 sides slightly convex, the posterior margin concave. Eyes very 

 small, composed of four facets, situated in the anterior fourth of 

 the head. Clypeus raised gradually towards the middle, the 

 anterior half minutely sub-carinate on each side of the median 

 line, and the anterior margin feebly bisinuate in the centre. 

 Frontal carinae convergent posteriorly and very small. Man- 

 dibles smooth, shining and sparsely punctured ; teeth very small. 

 The scape reaches back as far as the occiput, fiagellum one and 

 a half times as long as the scape, incrassate towards the apex, 

 2nd-10th joints broader than long. Pro-mesonotal suture distinct, 

 meso-epinotal much less so. Pronotum one-third wider and longer 

 than the mesonotum. Pro- and mesonotum convex. Dorsum of 

 epinotum convex transversely and widening towards the apex, 

 where it joins the declivity in a gradual curve ; declivity with the 

 lateral margins slightly raised. Node of petiole twice as wide as 

 long, rounded above and at the sides, vertically truncate behind and 

 obliquely truncate in front. Ventral lamella of petiole produced 

 into an obtuse point. Abdominal constriction moderate ; abdomen 

 a little longer than the thorax ; 1st segment narrower in front than 

 behind.

$ . 3 mm. Black, legs, antennae, and mandibles dark yellow. 

 Pilose hairs absent except on the clypeus, covered scantily all over 

 with a short pale pubescence. Microscopically punctured, sparsely 

 and shallowly on the thorax and first two abdominal segments, 

 more densely on the head and sides of epinotum. Head a little 

 longer than wide, sides and posterior margin almost straight or 

 only very feebly convex, posterior angles rounded. Clypeus raised 

 in the middle but not carinate, anterior margin convex. Frontal 

 carinae small, moderately angulated laterally in front. Eyes small, 

 situated low down and far forwards, separated from the base of the 

 mandibles by a distance equal to their own diameter. The scape
