The granulation of the elytra, and also the lateral serration is thafe 

 of Livingstoni, but the shortness of the elytra, the ampliation of the 

 sides in the middle, and their abrupt declivity behind approximates this 

 variety to scabra. 



Length, 42 ; width, 23™*""- 



I have seen one male only, which was captured by Mr. A. W, 

 Eriksson, in Ovampoland (Cunene River). 



M. FEROX. new species. 



plate 1, fig. 1. 



Brown, very shining ; jaws more slender than in the other species, 

 the two inner teeth of the left mandible far apart, and of equal size, 

 the apical 'one of the left with one or more minor teeth on each side, 

 somewhat like a shark's ; head and prothorax of the usual shape, but 

 hardly punctulated ; elytra nearly orbicular with the outer margins very 

 acutely serrated, sharply declivous behind, with the posterior part of 

 the disk somewhat convex, the upper part quite smooth, the declivity 

 with very small setigerous granules not closely set. 



Length, 30-45 ; width, 20-25™*™- 



Female : As shining as the male ; the granulation of the hind part is, 

 however, more pronounced, and there are also a few small tubercles 

 scattered on the lateral sides of the disk. 



Length, 39-44 ; width, 20-23™-™* 



This species is very distinct from the others ; not only are the elytra 

 more rotund than in any other, but the inner teeth of the mandibles 

 are also difiPerently shaped.
