ocellus and c1 ypeus ; its surface con- 

 vexorflat; raai'.yinsnotraised (fig-.2,a). 

 Elytra obliquely truncate apically ; the 

 reticulation in tha basal \mU dense, 

 with the cellules elongate (tig-. 5, A,B). 



3 (8). Elytra extending to the apex of the 



abdomen or even longer. Prozona not 

 or scarcely shorter than nietazona. 

 Prosternal spine straight, not at all 

 or scarcely inclined towards meso- 

 sternum, but not touching it. 



4 (7). Temporal foveolae distinct (tig. 4) ; mar- 



gins of the fastigium slightly raised. 

 Prozona subequal to metazona ; its 

 hind angle rounded (fig. 4). Elytra 

 with the veinlets in the apical part 

 not dense, fairly regular, oblique 

 (fig. 6, a).

only slightly broader than the frontal 

 ridge between antennae (fig. 4, C) ; eyes 

 at least twice as high as long f ; sub-

 length. Frontal ridge below the 

 ocellus slightly impressed. (Africa:

i' By the length of an eye I mean its horizontal diameter. 



+ Subocular distance is the distance between the lowest point of an 

 eye and the base of the mandible ; as a rule, this line is indicated by a 

 sulcus, which may be called the subocular sulcus.
