more parallel behind the middle ; the surface is sprinkled with 

 minute shining granules, as in G. mqpsus, but they are 

 smaller and only distinct at the front margin and front angles ; 

 there is a very shallow impression in the middle of the disk 

 and another at the base, and on each side of the disk there 

 are indications of similar impressions; near the front there 

 are two very inconspicuous shining spots ; the lateral fovea 

 is well marked. The elytra are dull, with the second and 

 fourth interstices very gently convex ; the surface is sprinkled 

 with minute shining granules, smaller and much less nume- 

 rous than in G. rnopsus. The anterior femora have a small 

 tooth on the front, rather beyond the middle. The meta- 

 sternum is more widely swollen in front than in G. mopsus. 



Gymnopleurus Jacksoni. 



iEruginosus, supra surdus ; capite antice bidentato ; thorace lato, 

 antice arcuatim angustato, confertim subtiliter rugoso, angiitis 

 posticis perparuni reflexis ; elytris confertim subtiliter rugosis, 

 stria suturali solum distincta ; metasterno antice paulo tube- 

 roso.

Hah. E. Africa, Masailand (F. J. Jackson, Esq.). 



Dark green, dull. Head finely rugose ; bidentate in front ; 

 the usual oblique ridges at the sides not extending far back. 

 Thorax very broad, closely and rather finely but distinctly 

 rugose, with a slight sinuosity behind the posterior angles, 

 which are rectangular (but obtuse at the very apex) and 

 slightly reflexed. The elytra at their widest part are scarcely 

 so wide as the widest part of the thorax ; the surface rugose 

 as the thorax. The anterior femora with a small tooth at 

 less than one third from the apex. Metasternum closely and 

 finely rugose in front, with a distinct round swelling in the 

 middle. Sides of the metasternum clotted with small tuber- 

 cles. Pygidium closely and finely rugose. 



This species is very near to G. liumanus, McL., but is a 

 little less finely rugose, has the posterior angles of the thorax 

 less prominent and less acute ; and the metasternum has the 

 anterior swelling rounded, and not at all pointed. 



Gymnopleurus Delagorguei. 



Oblongo-ovatus, paulo convexus, opacus, a^neo-fuscus, subtus asrugi- 

 noso-uiger ; capite crebre granulato, antice quadri-dentato ; thorace 

 creberrinie granuloso-rugoso, angulis posticis obtusis ; elytris 

 leviter striates, creberrime granuloso-rugosis, sutnra parum niticla ; 

 metasterno antice paulo obtuse tuberoso, granulato. 



Long. 17 millim.
