the margins of the dorsum. Both nodes transversely rugulose and 

 dull above. Abdomen and legs smooth and shining. Head, excluding 

 the mandibles, as long as, or a little longer than wide, widest in the 

 posterior half, the occipital emargination wide and fairly deep, not 

 acutely angular at its apex. Occipito-frontal sulcus shallow in front. 

 Eyes small, placed at the anterior fourth of the head. Frontal carinae 

 divergent, not extending back beyond the level of the hind margin of 

 the eyes. Clypeus with a fine median carina, shallowly emarginate 

 in front. Frontal area small and depressed. The scapes do not extend 

 back beyond the middle of the head. Posterior lateral angles of the 

 pronotum prominent and rounded at their apices. Pro-mesonotal 

 suture denned as a raised line. The transverse impression of the 

 mesonotum shallow, the scutellar portion short, not clearly denned in 

 front, slightly tuberculate on each side. Metanotal region indistinct. 

 Dorsum of epinotum widening towards the apex, a little wider than 

 long, moderately excavated in the middle and more or less margined 

 at the sides ; epinotal spines a trifle longer than their basal width, 

 acute, divergent, hardly half as long as the interval between their 

 bases ; the declivity longer than the dorsum. First joint of the 

 petiole a little longer than deep, the posterior-dorsal face a little wider 

 than long, the dorsal edge shallowly emarginate. Second node two 

 and two-thirds wider than the first, twice as wide as long, convex in 

 front, concave at the sides behind the spinose projections, the latter 

 varying from mere cones to more or less distinct, backwardly-curved 

 teeth. Abdomen truncate at the base. 



1/ minor. 4 - 6 mm. or less. The head is as wide or a little wider 

 in front than behind. Epinotal teeth shorter. The lateral projections 

 of the 2nd node shorter and more obtuse. Otherwise like the 1/ major. 



ty . 2 - 2-3 - 4 mm. Reddish-brown, the abdomen almost dark-brown, 

 the pro-mesonotum sometimes yellowish-brown, shining. Sides of the 

 head between the eyes and frontal carinae very shallowly reticulate, 

 the sides of the meso- and epithorax more strongly reticulate-punctate, 

 mesonotum shallowly rugulose, dorsum of epinotum feebly reticulate, 

 mandibles finely striate and subopaque, the rest of the body smooth. 

 Pilosity less abundant than in the 1/ . 



Head about as long as wide, the sides fairly convex. Frontal carinae 

 parallel, extending back as far as the middle of the head. The scapes 

 extend beyond the hind margin of the head by about the length of the 

 eye. Posterior lateral angle of the pronotum rounded. Transverse 

 impi*ession of the mesonotum very shallow. Dorsum of epinotum 

 longer than wide, faintly margined at the sides ; the epinotal teeth 

 small, acute, sub vertical, half as long as the interval between their
