"$, 8-5 mm. Black. Mandibles, trochanters and tarsi brownish. 

 Apical margins of abdominal segments narrowly reddish. Shining. 

 Occiput, sides of the head and pronotum, mesopleura, epinotum and 

 scale very finely reticulate-punctate. Erect pilosity fine, woolly, 

 sparse on the head and thorax, more abundant on the abdomen. 

 Pubescence golden and oblique, fairly scanty, quite distinct and 

 exserted on the cheeks. 



Head about one-sixth longer than wide, subtruncate in front. 

 Occipital margin widely concave, the posterior angles distinct although 

 rounded. The sides are a little convex, particularly behind the eyes. 

 The latter are placed a little behind the middle of the sides, of which 

 they occupy about a fourth. The distance between the frontal 

 carinae is about equal to their distance from the eyes. Frontal 

 area small, not very distinct, followed by a median sulcus which 

 does not extend beyond the level of the ends of the frontal carinae. 

 Ocelli small and fairly close together. Clypeus convex, not carinate, 

 the anterior margin fairly arcuate. Mandibles punctured, striate, 

 narrow, the inner and outer margins subparallel, the masticatory 

 margin armed with a strong apical tooth and four small teeth behind 

 it. Thorax elongate, a little narrower than the head, higher than 

 wide. Lateral margins of pronotum rounded, the shoulders distinct 

 but rounded. The mesonotum and scutellum form an oval disc, 

 nearly twice as long as wide, separated by a semilunar groove which 

 does not reach the outer margins. Metanotum very narrow, not much 

 depressed. Dorsum of the epinotum as long as the declivity, not 

 marginatc, evenly convex transversely, feebly convex lengthwise, 

 armed with two short, thick and upturned teeth. Declivity vertical
