anteriorly, rounded at the sides of the pronotum. The margin of the 

 thorax between its sides and upper surface is Insinuate, shallowly so at 

 the pro-mesonotal suture, more deeply at the meso-epinotal, the latter 

 being distinctly impressed ; the dorsum of the epinotum is feebly 

 convex, a little longer than wide, with two blunt spines behind, which 

 are about half as long as the dorsum, and directed backwards, out- 

 wards and upwards. The 1st joint of the petiole has a short 

 peduncle, and is closely reticulate-punctate and also coarsely rugose ; 

 its node has a quadrangular dorsal surface, which is feebly convex 

 transversely and lengthwise, and distinctly wider than long, the 

 anterior corners strougly rounded. The dorsal surface is delimited 

 from the anterior face by a nearly rectangular margin ; the anterior 

 face is vertical above, sloping forwards below ; the posterior face of 

 the node is very short and vertical, and merges gradually into the 

 upper surface. On each side of the node, a little below the hind 

 angles, there is a small pointed tooth with a hair or bristle at its apex, 

 and there are one or two similar but smaller projections in front of 

 these on the dorsal lateral margins of the node. The 2nd node of the 

 petiole is about one and a half times as wide as long, somewhat wider 

 than the 1st, and has traces of two small teeth or tubercles like those 

 of the 1st node on each of its rounded sides. The abdomen is shining, 

 very shallowly rugulose, and with some scattered piligerous punctures, 

 almost smooth.
