carinaB very short, twice as far apart as their distance from the 

 lateral borders of the head, running back towards the anterior 

 orbits. Frontal area and gi'oove obsolete. Antennae short, 8-jointed, 

 scapes somewhat thickened apically^ not reaching to the posterior 

 orbits; funiculi gradually thickened to their tips, all their joints 

 longer than broad. Thorax long and slender ; broadest through the 

 pronotum, much narrowed at the mesonotum; pronotum seen from 

 above elliptical, a little longer than broad, its dorsal outline evenly 

 rounded, continued back into that of the sloping mesonotum to 

 the constriction, which is sellate and bears on each side a swelling 

 with t)ne of the metanotal spiracles. Base of epinotum rising 

 somewhat above the constriction, slightly but distinctly convex, 

 longer than the feebly concave, sloping declivity. From above the 

 epinotum is a little longer than broad and slightly narrower than 

 the pronotum, the mesonotum less than half as broad as the latter. 

 Petiolar node nearly as high as the epinotum, transverse, erect, 

 as thick above as below, its anterior and dorsal surface roundea, 

 its posterior surface more flattened ; seen from behind it is broader 

 above than below, with broadly rounded superior corners. Gaster 

 moderately large, elliptical, its first segment not longer than the 

 second. Legs moderately long, femora all distinctly incrassated at 

 the base, tibise subcylindrical, their bases slightly constricted. Tar- 

 sal claws slender and rather straight. 



Shining; finely but sharply shagreened; thorax and petiole, ex- 

 cept the pronotum, subopaque, finely and densely punctate. Man- 

 dibles, clypeus and front of head with fine, dense, superficial, longi- 

 tudinal striae. 



Hairs and pubescence whitish; the former absent except on the 

 clypeus, palpi and tip of the gaster ; the pubescence extremely short 

 and dilute, distinct only on the antennal funculi. 



Dull honey A'ellow ; legs scarcely paler ; mandibles, clypeus and 

 antenniy more whitish; eyes black; mandibular teeth reddish brown. 



Worlcer minor. Length 2. 3mm. 



Differing from the inajor in its smaller size, narrower head, 

 proportionally larger, more prominent and slightly more reniform 

 eyes, even more minute ocelli, shorter, less angular and anteriorly 

 more convergent cheeks; longer and more anteriorly produced 

 clypeus and more slender mandibles.
