the pronotum shining, 2nd node of petiole and the abdomen smooth 

 and very shining. Head elongate, einarginate behind, narrowed in 

 front, clypeus convex, arcuate in front, mandibles porrect, the masti- 

 catory margin very long and nearly straight from the clypeus to the 

 apex, minutely denticulate ; 4th joint of the flagellum hardly shorter 

 than the preceding three taken together. Thorax evenly convex over 

 ' the pro-mesonotum, the dorsum of the epinotum depressed, the spines 

 short, the declivity margined with spongy bands. Peduncle of the 1st 

 joint of the petiole long, the node subglobose, reticulate ; 2nd node 

 transversely ovate and shining.

" This species is remarkable on account of the very elongate form of 

 the mandibles (the teeth of which are numerous and excessively 

 minute). . . . The head, mesonotum, epinotum and the 1st node 

 are very closely reticulate-punctate and dull, the rest is shining. 

 There are no striae at the base of the abdomen. The spongy appen- 

 dage of the petiole is only feebly developed. The head bears some 

 small curved and squamiform hairs ; clavate hairs occur only on the 

 petiole and abdomen."

$ . 2"l-24 mm. Dark brownish-red, legs, antennae and mandibles 

 dark yellow. Head, meso- and epinotum and 1st node reticulate- 

 punctate and dull ; pronotum moderately shining, sparsely and feebly 

 striate, narrowly carinate in the middle. Declivity of the epinotum, 

 2nd node and abdomen smooth and shining, the latter longitudinally 

 striate over the basal third. Pilosity fairly sparse on the head, very 

 sparse on the nodes and abdomen, the epinotum glabrous. The 

 pilosity consists of clavate hairs, curved and flattened on the head, 

 longer and erect elsewhere. The broad spatulate hairs present in the 

 other species are absent. The two outermost hairs on the anterior 

 margin of the scape are directed outwards, the rest inwards. On the 

 thorax there are only two clavate hairs, one on each side of the middle 

 of the mesonotum. .Head, measured from the anterior margin of the 

 clypeus to the middle of the occipital' margin, very little longer than 

 wide, the sides not very convex, the posterior margin fairly deeply but 

 not widely einarginate. The scrobes are well defined and fairly deep, 

 and with the scapes extend back almost to the end of the posterior 

 angles. Frontal carinae prominent. Eyes small, composed of about
