^ • 3 - 5-3*6 ram. Piceous, legs yellowish-brown, antennae and 

 mandibles somewhat reddish-brown. Head sometimes paler. Pilosity 

 yellowish, fairly long, composed of thin and pointed hairs, not very 

 abundant. Legs and antennae with a scanty yellowish pubescence, 

 which is absent from the body. Moderately shining, strongly rugose, 

 longitudinally so on the head, and reticulate-rugose on the thorax. 

 The rugae on the head connected by a few transverse branches. 

 Apical half of the dorsum and the declivity of the epinotum, the 

 nodes and abdomen smooth and shining. Head slightly longer than 

 wide, the sides moderately convex, the posterior margin almost 

 straight, the posterior angles rounded, hardly narrower in front 

 than behind. Eyes occupying about one-quarter of the sides, placed 

 a little in front of the middle. The frontal carinae extend back as 

 strong ridges nearly as far as the occiput, and form the upper 

 boundary of the demiscrobes, which are smooth and fairly deep. 

 The scapes do not reach the occipital margin ; 2nd-7th joints of the 

 flagellum wider than long. Clypeus coarsely and sparsely rugose, 

 with a strong median carina. Mandibles closely and finely striate, 

 armed with two distinct teeth in front, and five obtuse and smaller 

 teeth behind. Pronotum submarginate in front and at the sides, 

 the shoulders rounded. Pro-mesonotal suture feeble, meso-epinotal 

 suture shallow and wide. Dorsum of epinotum longer than wide, 

 hardly wider at the base than at the apex, a little longer than the 

 vertical declivity ; the latter marginate at the sides. Epinotal spines 

 very long, acute, strongly divergent and not very oblique, much 

 longer than the interval between their bases and as long as the 

 dorsum of the epinotum. Episternal teeth small. Peduncle of the 

 1st segment of the petiole as long as the node ; the latter much 

 higher than long, truncate in front, the anterior dorsal margin 

 convex transversely, the dorsal face convex lengthwise and sloping 

 downwards posteriorly ; seen from above, about as wide as long and 

 wider in front than behind. 2nd node transversely oval, three-quarters 

 wider than long, and a little wider than the 1st. Abdomen decidedly 

 convex above. 



9 . 4 - 2 mm. Sides of the head behind the eyes more convex 

 than in the <J . Pronotum coarsely reticulate-rugose. Mesonotum 

 and scutellum sharply striate, the striae larger and wider apart on 

 the scutelluui. Epinotum longitudinally rugose at the sides and 

 above, near the base, fairly smooth elsewhere. Dorsum of the 

 epinotum short, sloping from its base downwards to the longer and
