occipital margin straight. Median area of clypeus raised, obtusely 

 bicarinate, the front margin of the median area feebly concave. 

 Frontal carinae short and parallel. A shining and smooth line on the 

 vertex extends back from the end of the clypeus to about the level of 

 the eyes. The latter not large, situated just in front of the middle 

 of the sides. Mandibles longitudinally striate, elongate, armed with 

 4 teeth, the apical and sub-apical acute. Scape of antenna long, 

 extending beyond the occipital margin, 1st joint of flagellum two and 

 a half times as long as the second, the club, composed of the three 

 apical joints, is as long as the rest of the flagellum. The pro-meso- 

 notum is widest at the anterior fourth ; the thorax is rather strongly 

 constricted at the meso-epinotal suture, which is deep. Epinotum 

 longer than wide, widest at the middle, two-thirds the length of the 

 pro-mesonotum, the declivity oblique and about half as long as the 

 dorsum, the brow of the declivity considerably rounded. First joint 

 of petiole with the peduncle half as long as the node, the latter longer 

 and higher than wide, higher than the 2nd joint. The latter is about 

 as long as wide, sub-quadrate, the anterior margin rounded. First 

 segment of abdomen longer than wide, and twice as long as the 

 remaining segments taken together. Legs long and slender. 



? (hitherto undescribed). 7 mm. Black; mandibles, antennae 

 and legs dark reddish brown, the tarsi paler. Dull, except the basal 

 two-thirds of the second and following abdominal segments, which are 

 smooth, shining and alutaceous. Clypeus longitudinally striate, the 

 rest of the head strongly, and more or less longitudinally rugose, the 

 rugae with a few transverse anastomoses, and also partly radiating- 

 outwards from the median ocellus. Mandibles strongly striate. 

 Mesonotum and scutellum longitudinally and somewhat obliquely 

 striate, the striae on the mesonotum thickening posteriorly, the space 

 between the striae closely reticulate-punctate. Epinotum coarsely and 

 irregularly rugose at the sides, transversely on the declivity, the space 

 between the rugae closely punctured. Second node, and posterior 

 face of the 1st node transversely rugose, more coarsely on the latter. 

 First segment of abdomen, and marginal third of the remaining 

 segments distinctly and regularly striate, longitudinally so over the 

 basal half and the sides of the 1st segment, arcuately and transversely 

 over the apical portion of all the segments. Legs and antennae with 

 a short, sparse pubescence. Head, mesonotum, petiole, and abdomen 

 with pale pilose hairs, which are longest on the clypeus, petiole, and 

 margins of the abdominal segments. Head more quadrate than in 

 the ^ ; eyes occupying about one-fifth of the sides, and placed in the 

 middle, the ocelli not large. Pronotum not exposed above. Thorax
