equal length in the 2 ', sternal process long, horizontal, acuminate 

 at apex ; under side sparingly hairy ; inner part of intermediate and 

 posterior tibiae fringed with very dense flavescent or black hairs. 



The genus is represented in Western and East Central Africa, and 

 includes species attaining the largest size in the Order Coleoptera.

Male : Black head and clypeus coated with white in the upper 

 part, but still distinctly carinate longitudinally, the deflexed sides and 

 the furcate process black ; antennae piceous ; prothorax with a broad 

 lateral marginal white band enclosing in the anterior part an 

 elongated patch of the black background, a narrow discoidal one 

 on each side, and a narrower one in the central part, all these bands 

 reach from apex to base ; the black parts are quite opaque, and the 

 sub-velvety coating hides the sculpture ; scutellum with a median 

 white line and a broader lateral one filling the lateral groove ; elytra 

 broadly white laterally and behind with the black discoidal part 

 including both the anterior and posterior callus interrupted by 

 transverse, sinuose, somewhat narrow white bands ; the sculpture 

 is hidden by the black and white coating ; pygidium black, fringed 

 with black or more or less light fulvescent, fairly long hairs ; 

 abdomen glabrous, pectus briefly pubescent ; abdomen, pectus, and 

 femora closely punctate ; median part of metasternum smooth, 

 grooved to a short distance from the apex, where there is no trace 

 of suture. 



Female : Head very rugose, black with only the frontal part white, 

 and carinate longitudinally in the frontal part only ; prothorax 

 punctate foveate, impressed longitudinally in the centre of the 

 anterior part, the impression ending in a sharp tubercle in the 

 anterior margin, and having a narrow white line in the centre 

 reaching from the apex to the middle, a shorter discoidal one 

 beginning at the apex, and a broad marginal one enclosing a long 

 band of the black background ; the disposition of the white sinuate 

 bands on the black, not opaque background is the same as in the 

 male, but the punctures on the surface are quite distinct ; under side 

 as in the male but more deeply punctured, and with the sternal 

 process more triangularly acute at the tip. 



I am informed that in G. kirki, the pubescence on the margin 

 of the pygidium, and on the inner part of the legs is fulvescent
