a strong magnification. The colour is very pale, of a reddish-yellow, 

 the abdomen, femora and tibiae partly blackish.

The type species has not yet been recorded from our region, it is 

 characterised as follows : 



" £ . 27 mm. Dull ; ferruginous, abdomen brown, with the 

 margins of the segments paler and the apex rusty. Head reticulate, 

 finely granulate in between. Mandibles striate, the clypeus depressed 

 in front, finely carinate in the middle, distinct from the frontal area. 

 Frontal carinae produced backwards over three-quarters of the 

 length of the head. The 12- jointed antennae are rather slender, 

 the 1st joint of the flagellum is as long as the two following taken 

 together; the club three-jointed, only slightly incrassate and distinctly 

 shorter than the rest of the flagellum. The thorax is longitudinally 

 rugose on the pro- and mesonotum, transversely so on the epinotum ; 

 the meso-epinotal suture deep. The epinotum is armed with two 

 nearly horizontal spines, slightly divergent, wide at the base,, fairly 

 acute ; there are two smaller episternal spines below. The petiole is 

 finely coriaceous, the node of the 1st segment is hardly longer than 

 wide ; the 2nd segment is subglobose, a little wider behind, slightly 

 transverse. The abdomen is dull, with a velvety, silky sheen, due 

 to the very dense and fine striation. The whole body is sparsely 

 clothed with pale hairs, not clavate ; those on the abdomen are 

 longer."

" ^ . 4 mm. Piceous ; mandibles, tarsi and articulations of the 

 legs rufescent ; dull ; barely pilose and very sparsely pubescent. 

 Head reticulate-rugose lengthwise, clypeus striato-rugose, mandibles 

 very finely striate, meso-epinotal suture deep, pro-mesonotal suture 

 obsolete. Pro-mesonotum strongly convex, coarsely rugoso-reticulate, 

 the convex epinotum also, but without the coarse reticulations. 

 Epinotum armed with two minute spines, erect, acute ; episternal 

 teeth absent. Nodes of petiole subequal, globose, hardly more finely 

 reticulate than the epinotum. The abdomen subopaque, very finely 

 punctured, the extreme base striolate.

" Remarkable on account of the profile of the thorax and petiole, 

 which forms a series of l'ounded bosses, and also by the sculpture. 

 The latter consists of a network of coarse rugae, mostly longitudinal.
