profile slightly constricted between the meso- and epinotum. A fine 

 transverse ridge separates the pronotum from the mesonotum. From 

 the ridge forwards, the pronotum slopes downwards to the neck (not 

 vertically so, as described by Forel). Dorsum of the epinotum one 

 and a half times longer than wide, widest at the basal third, longer 

 than the declivity. Epinotal spines acute, longer than their basal 

 width and a little longer than the space between their bases, slightly 

 divergent, directed very obliquely upwards. Declivity subvertical, 

 margined at the sides, the episternal teeth small and triangular. 

 Peduncle of the petiole a little shorter than its node. The latter 

 truncate in front, the anterior face shorter than the oblique posterior 

 face. The dorsal and posterior faces, taken together, longer than 

 wide, the anterior border above margined with a dark line. Second 

 node shorter than the 1st, nearly twice as wide as long, wider than the 

 1st, transversely oval. Femora only slightly swollen. 



9. 52 mm. (Hitherto undescribed.) Colour like that of the £, 

 but a little darker; tegulae, metanotum, and posterior margin of the 

 scutellum almost black. Sculpture of the head stronger than in the 

 ty ; the frontal carinae more pronounced, mesonotum and scutellum 

 shining, more so than in the ^ , closely and finely longitudinally 

 striate. Epinotum rugulose above, and also partly reticulate-rugose at 

 the sides. " Epinotal spines much more robust than in the ^ , acute, 

 about as long as their basal width. Nodes much shorter and wider 

 than in the £ ; the dorsal face of the 1st node more sharply delimited 

 from the oblique posterior face, and nearly three times wider than 

 long ; the 2nd node has the anterior face almost vertical and the sides 

 subangularin the middle. Deiilated. Otherwise like the ^ .

 " ^ . 45 mm. Black ; mandibles, antennae, tarsi, peduncle of 

 1st node of the petiole, and the apex of the abdomen rusty red. 

 Middle of the femora brownish. Sometimes a part of the 2nd node 

 and the base of the abdomen very dark red. Shining. Strongly and 

 regularly striate, the intervals between the striae smooth, or here 

 and there, finely reticulate. Striae on the head longitudinal, those 

 above diverging from the occiput and anastomosing behind the eyes 

 with the striae from below. Transversely striate on the pronotum, 

 longitudinally so on the rest of the thorax, the striae forming con- 

 centric curves on the pronotum. Declivity of epinotum smooth, with
