cate anterior angles. From these truncate angles to the posterior 

 margin the sides are concave. Second segment nearly twice as wide 

 as long, vei'y shallowly impressed above. Abdomen almost truncate 

 in front, acute apically. Legs fairly long. Moderately shining. 

 Head quite finely, the thorax more coarsely longitudinally rugose 

 (the striae on the epinotum divergent), and reticulate between the 

 striae. Clypeus very superficially rugulose like tbe abdomen. 

 Petiole almost reticulate only. Body and limbs with a sparse, fine 

 and yellowish pubescence, pilosity absent. Black ; mandibles, antennae 

 and legs blackish-brown. 



" $ . 4 - 5 mm. Mandibles narrow, sickle-shaped as in Polyeryus, 

 with the apex acute, shining, striate, punctate. Head short, widely 

 truncate in front up to the level of the frontal area, somewhat as in 

 Colobopsis, but the truncated face is only obtusely and indistinctly 

 marginate. Clypeus almost flat, without a carina, feebly emarginate 

 in the middle in front. Behind the eyes the head is abruptly nar- 

 rowed and almost trapeziform, but not narrowed in a neck-like manner, 

 the posterior margin consisting of the articular border only. The 

 scape extends beyond the posterior margin by two-fifths of its length ; 

 the joints of the flagelrum are longer than in the ^ . Frontal carinae 

 as in the $ . Thorax narrower than the head ; the mesonotum over- 

 hangs the pronotum to a certain extent in f i*ont. Metanotum pointed, 

 projecting in an almost dentiform shape over the epinotum. Scutellum 

 large. Epinotum quite unarmed, declivous, with a very short dorsum. 

 First segment of petiole wider than long, concave in front, otherwise 

 as in the ^ . Second segment more than twice as wide as long, in 

 front wider and produced laterally. Abdomen, frontal area and 

 clypeus smooth ; only a few transverse rugae in front on the clypeus. 

 Legs and antennae shining, with numerous piligerous punctures. 

 Otherwise the head, thorax and petiole are nearly dull, closely and 

 rather coarsely longitudinally rugose, and coarsely reticulate-punctate 

 or reticulate in between the rugae. The scutellum and declivity of the 

 epinotum like the rest. Legs and antennae with abundant decumbent 

 hairs, head, thorax and petiole with dark yellowish exserted hairs. 

 Abdomen almost glabrous. Brownish-black, abdomen, the front of 

 the head, antennae and legs brown. Mandibles brownish-red. Wings 

 hyaline, with pale nervures and stigma. 



" ^ . 8 mm. Mandibles narrow, with only an apical tooth. Head 

 rather wider than long, with a distant hind margin. The mesonotum 

 overhangs the pronotum. Thorax somewhat wider than the head. 

 Epinotum unarmed, but with 2 well-defined faces, the dorsal one 

 short and nearly horizontal. Nitidulous. Head and thorax finely
