distinct depression. Mandibles with oblique, Maothed blades, the I 

 teeth separated. Clypeus bicarinate, its anterior border with two stout 

 median and two very small lateral denticles, Frontal area small, crescentic; 

 frontal groove distinct; frontal carinae very short. Antennae II jointed] 

 Bcapes not reaching to tin- posterior corners of the head; second funicular 

 joint longer than broad; joints 3-8 fully as long as broad; basal joint of clava 

 about half as K > i ija as the terminal joint. Thorax elliptical, robust, distinctly 

 broader than the head; mesonotum nearly twice as long as broad; pronotum 



vertical in profile; epinotum abruptly sloping, Bhort, with Bubequal base arid 

 declivity meeting at a rounded, very obtuse angle. Petiole somewhat longer 

 than high, with short peduncle, furnished with a -mall ventral tooth at the 

 anterior end, node from above somewhat transverse, broader than long, com- 

 pressed anteroposteriorly. Postpetiole a little broader than the petiole, its 

 node broader than long, very convex and rounded above. ( iaster large, 

 elliptical. Legs rather short. 



Shining; mandibles very indistinctly striatopunctate, almost smooth. 

 Head uniformly and rather coarsely punctate, front very finely and densely 

 longitudinally striate; remainder of body with extremely fine, sparse, piliger- 

 ous punctures. 



Hairs w r hite, very delicate, erect and abundant but rather short on the upper 

 surface of the head, thorax, and pedicel, shorter and sparser on the gaster and 

 appendages, somewhat oblique on the latter. 



Yellowish brown; head darker and more reddish above; venter, posterior 

 borders of gastric segments, mandibles, clypeus, cheeks, and appendages 

 yellow; mandibular teeth dark brown. Wings whitish hyaline, with almost 

 colorless veins and pale brown pterostigma. 



Male. Length, 2.5-3 mm. 



Head, including the eyes as broad as long, somewhat flattened above, semi- 

 circularly rounded behind, with very short cheeks. Mandibles slender, with 

 three subequal teeth. Clypeus convex in the middle, without carinae, its 

 anterior border feebly concave, edentate. Antennal scapes very short, as 

 long as the two basal funicular joints together; first funicular joint swollen, a 

 little longer than broad. Thorax like that of the female, but the epinotum 

 more convex, with round, sloping base, much longer than the concave declivity. 

 Petiole without a ventral tooth, its node very low; postpetiolar node flattened 

 above. Legs slender. 



Body smooth and shining as in the female, but head without coarse punc- 

 tures, merely finely reticulate on the cheeks and behind the ocelli. 



Hairs on the head, thorax, and pedicel much shorter and less abundant, 

 those on the appendages very fine, sparse, and closely appressed. 



Color like that of the female, body and head a little darker. Wings as in the 

 female.
