Hah. Matadi, Africa. (In the collection of the Belgian Mus. 

 and that of my own.) 



Differs from L. rubrieoUis Lac. in the colour of the legs and that 

 of the underside, from L. ganguinicollis Lac. in the differently 

 structured thorax : L. rufo-femorata Clark is black below and lias 

 rufous femora : L. affinis CI. differs similarly. 



Lema bomaexsis, sp. n. 



Flavous, the terminal joints of the antennae fuscous; thorax sub- 

 cylindrical, sparingly punctured, with some obscure piceous spots: 

 elytra strongly and closely punctate-striate, the sutural margin 

 and a broader sublateral stripe, abbreviated posteriorly, blackish. 



Length 5 millim. 



Head impunctate, flavous, the vertex sometimes obscure piceous: 

 eyes entire, not notched, supra-ocular grooves shallow; elypeus 

 triangularly raised; labrum piceous; antenme short and robust, the 

 lower joints short, the fifth elongate, terminal joints widened, 

 more or less stained with fuscous ; thorax short, subcvlindrical. 

 strongly constricted at the base, the basal sulcus deep, the disc 

 with some strong, scattered punctures at the sides and at the 

 middle, the latter with some obsolete piceous spots (sometimes 

 absent); scutellum piceous, its apex truncate; elytra parallel, with 

 a very shallow depression below the base, very strongly punctured 

 in closely approached rows, the interstices costate from the middle 

 downwards, flavous, the suture very narrowly and a broader stripe 

 from the shoulder to below the middle piceous or black : below and 

 the legs flavous. the breast darker, covered with very short velioM 

 pubescence. 



Bab. Boma, Congo. (Coll. Belgian Mus. and my own.) 



A very distinct species, remarkable on account of the entire 

 eyes, shape of the thorax, which is strongly widened in front, and 

 the pattern of the elytra.
