the rest of the abdomen smooth and very shining. Clypeus almost 

 smooth, with a strong median carina, the anterior margin distinctly 

 excised in the middle. Mandibles striated at the base externally, 

 the rest smooth and shining, sparsely punctured with large punc- 

 tures. 



Head, excluding the mandibles, about one-eighth longer than wide, 

 very slightly narrowed in front of the eyes ; behind the eyes the sides 

 are straight and parallel as far as the posterior fifth, thence convex and 

 convergent. Occipital lobes rounded, the posterior margin fairly 

 deeply and arcuately emarginate, the occipito-frontal sulcus rather 

 shallow. Head highest in the middle, not concave at the sides 

 behind the eyes. The latter placed at about the anterior third of the 

 sides, convex and not small. Scape of antenna long, extending back 

 as far as the posterior fifth of the head ; flagellum long and slender, 

 all the joints much longer than wide. Pronotum short, its posterior 

 lateral angles rounded and not prominent. Pro-mesonotal suture

obsolete. Mesonotum submarginate at the sides, transversely 

 impressed in the middle, without a distinct transverse torus in front 

 of the scutellar region. Meso-epinotal suture deep. Dorsum of 

 epinotum at least one and a-half times longer than wide, almost flat, 

 or only very feebly excavated longitudinally towards the apex. Epi- 

 notal spines vertical, barely divergent, thin, subacute, longer than 

 their basal width and longer than the interval between their bases. 

 Declivity as long as the dorsum of the epinotum. The peduncle of the 

 1st segment of the petiole is as long as the node ; the latter has a thick 

 dorsal edge which is feebly emarginate in the middle. Second 

 segment of the petiole hexagonal, about one-fifth longer than wide, 

 narrower in front than behind, the sides obtusely angulated. Abdo- 

 men a little longer than wide. 



^ . 2*6-3 mm. Head, thorax and petiole varying from recldish- 

 ochreous-yellow to yellowish-red, abdomen dark ochreous, or in some 

 specimens pale piceous. Legs and antennae ochreous yellow. 

 Pilosity shorter and less abundant than in the %, the pubescence on 

 the legs and antennae more erect than in the 3/ .
