margin are very small. The 2nd node of the petiole is twice as wide 

 as long, and seen from above, has a short dilatation on each side which 

 resembles a very small hook, bent backwards (often less distinct in 

 the ^)."

" $ • Differs from the type from Delagoa Bay by the finer sculpture 

 of the abdomen (connecting it with intrudens, Smith). It is almost 

 as strong and coarse on the dorsum of the thorax as in the type, but 

 more regular and more parallel. The spines of the epinotum are a 

 little shorter and the lateral teeth of the dorsum smaller.

" £ . 3*4-3 - 7 mm. Smaller than rugosus. The head not much 

 narrowed in front, more so in rugosus. The thorax above, a little 

 more arched lengthwise over its posterior half than in rugosus. The 

 mesosternum on each side has a forwardly directed and acute tooth at 

 the lower and anterior corner, just in front of the articulations of the 

 middle pair of coxae ; in rugosus this tooth is shorter, as long as, or 

 shorter than its basal width. The epinotal spines are shorter than in 

 rugosus, and tbeir apices more or less distinctly obliquely truncate and 

 rounded, whereas in the other species they are simply acute. The 2nd 

 node rounded at the sides, hardly wider in front than the 1st (in 

 rugosus the 2nd is distinctly wider than the 1st, and there is often a 

 small tooth at the sides). Abdomen glossy or moderately shining 

 (dull in rugosus), and much more shallowly sculptured." 



Dr. Forel separates this form from rugosus on account of its smaller 

 size, and the shape of the 1st node of the petiole. This is almost 

 conical, with an anterior-dorsal face which is smooth ; its summit 

 behind is emargiuate in the middle. In rugosus the node is cubic,
