latter, which are simple with the trochanters not projecting into a 

 spine, but are bluntly dentate on each side of the articulation of the 

 knee ; hind tibiae thick, swollen inwardly and outwardly, slightly 

 angular near the knee with the lower apical part very sharply 

 angular, and the upper part developed into a long spinose mucro ; the 

 four basal joints of the hind tarsi are short and very robust, and the 

 fifth is greatly developed, thick, as long as the four preceding and 

 denticulate underneath, outer claw very robust, as long as the fourth 

 joint, simple, inner claw very minute ; the claws of the two first pairs 

 of legs are double and both cleft. 



Female : The female is shaped like the male, except that the 

 pygidium is sub-horizontal ; the anterior tibiae are, however, more 

 distinctly tri-dentate ; the discoidal part of the prothorax and of the 

 elytra is sprinkled with numerous scales, not as closely set, however, 

 as those on the marginal and juxta-sutural bands, and these scales 

 have a more golden sheen than in the male ; the hind legs are also 

 robust. 



Length 5^-9 mm. ; width 3-5 mm. 



Hab. Transvaal (Lydenburg, Eustenburg), Southern Rhodesia 

 (Salisbury), Mozambique (Louren9o-Marquez), Bechuanaland 

 (Eamoutsa). 



The examples from Southern Ehodesia are much smaller than the 

 others and less brightly scaly.

 Mentum sub-orbicular, rounded also at tip, and only very slightly

 margin refiexed ; prothorax obliquely attenuate laterally in the 

 anterior part, and straight from there ; scutellum somewhat rounded 

 at apex ; elytra attenuate laterally towards the apex, slightly sinuate 

 laterally past the humeral part, but covering the dorsal part of the

 nearly completely covered by the elytra {G. aliena) or moderately 

 exposed {G. lineolata) ; anterior tibiae tri-dentate, the teeth oblique ;
