on the middle of the head and on the dorsum of the thorax. The 

 coarsest rugae are on the pro-mesonotum, those of the head, epinotum 

 and petiole becoming successively finer. In addition to the reticula- 

 tions, there is a fundamental puncturation, which is fairly close and 



more or less visible, The frontal carinae ai-e produced 



backwards as feeble ridges, hardly more pronounced than the neigh- 

 bouring rugae, and forming no distinct scrobe."

ty. 4 - 3-4*7 mm. Dark brown, abdomen piceous, femora and 

 middle portion of the scapes lighter brown ; tibiae, tarsi, flagellum, 

 base and apex of the scape, and the mandibles brownish-yellow. A 

 few yellowish hairs on the clypeus and apex of abdomen, otherwise 

 without pilosity. Pubescence very short and scanty, almost absent on 

 the body, a little more noticeable on the legs and antennae. The 

 middle of the head above, longitudinally striate. The clypeus has a 

 median carina which is continued back to the posterior margin of the 

 head ; sides of the head finely reticulate, somewhat more coarsely so 

 on the anterior half, which is also partly rugose. Pronotum very 

 finely and longitudinally striato-rugulose ; mesonotum smooth and 

 shining in the middle, faintly striate at the sides ; epinotum, nodes, 

 and basal half of abdomen closely and finely reticulate and dull. The 

 rest of the abdomen, and also a narrow median area on the 1st node, 

 slightly shining and almost smooth. 



Head about one-fifth longer than wide, the sides parallel, the 

 posterior angles rounded, the hind margin shallowly concave. The 

 scapes extend back almost as far as the hind margin of the head and 

 are rather strongly curved near the base ; 2nd-8th joints of the 

 flagellum wider than long. Eyes fairly large and prominent, convex, 

 placed in the middle of the sides. Scrobes absent. Mandibles 

 shining, finely striate, armed with 7 small and obtuse teeth, the 

 masticatory margin black. Pronotum truncate in front, the face so 

 formed short, the shoulders obtuse. Thoracic sutures obsolete. 

 Mesonotum with a slight angular enlargement on each side behind 

 the middle. Epinotum moderately oblique, the dorsum one and a 

 half times longer than wide, widest near the base. The declivity is 

 almost vertical, hardly half as long as the dorsum, margined at the 

 sides by a ridge which ends above and below in the teeth. The 

 epinotal teeth are shorter than the interval between their bases, as 

 long as wide at the base, divergent, directed obliquely upwards ;
