of short hairs ; legs fulvous ; all the femora armed with a small 

 tooth. 



Hob. Kamozi, Tumbu {J. Duvivier). (Coll. Belgian Mus. and 

 my own.) 



Unlike the other two or three species of the genus, the present 

 one has armed femora, but agrees in all other details : this and the 

 colour of the legs will easily distinguish the species. 



CORYNODES NIGRIPENNIS, sp. n. 



Bluish black, the head and thorax rufous, the latter very finely 

 and subremotely punctured ; elytra black, opaque, very closely 

 and finely rugosely punctured, the claws appendiculate. 



Length 11 millim. 



Of subcylindrical, parallel shape ; the head impunctate, rufous, 

 shining ; the clypeus triangular, deeply separated from the face by 

 a transverse, medially interrupted groove; antennae nearly extending 

 to the middle of the elytra, black, the second and third joints fulvous 

 below, the terminal six joints strongly flattened ; thorax of the same 

 shape as in the preceding species, rufous, very shining, extremely 

 minutely and sparingly punctured, the extreme anterior and basal 

 margins black ; scutellum fulvous, margined with black ; elytra 

 closely and somewhat strongly punctured, black, the interstices 

 finely rugose, the extreme apex with a small obsolete fulvous spot ; 

 below and the legs bluish black, the anterior tibiae strongly curved 

 at the apex. 



Hab. Cameroons. 



This species, of which I have received a single specimen from 

 Herr Bang-Haas, agrees so closely in structural characters with the 

 following, that I am almost tempted to look at it as an extreme- 

 variety of the latter ; but the coloration of the head, thorax, and 

 that of the elytra (unique amongst the numerous members of the 

 genus) is so entirely different, that, in the absence of intermediate 

 forms, I must consider the two insects distinct. 



CORYNODES BIMACULICOLLIS, Sp. n. 



Bluish black below, as well as the legs and antennae, above 

 fulvous : thorax impunctate, the anterior and basal margins and two 

 elongate spots on the disc black ; elytra very closely punctured, 

 claws appendiculate. 



Length 11 millim. 



Head impunctate, fulvous, a small spot at the vertex and the 

 supra-ocular sulci black ; clypeus separated from the face by a 

 deep transverse groove ; antennae black, the lower two joints fulvous, 

 the apical five joints gradually and broadly flattened ; thorax 

 about one half broader than long, narrowed anteriorly, the sides 

 straight, the surface impunctate, the extreme anterior and basal 

 margins black, the disc with two large, oblique, elongate black 

 spots ; scutellum fulvous, margined with black ; elytra evenly, 

 closely, and distinctly punctured, the interstices slightly wrinkled 

 here and there ; anterior tibiae strongly curved at the apex.
