402 M. JACOBY ON NEW SPECIES OF BEETLES. [JutlC 19, 



and the antennae black ; elytra very finely and closely punctured, 

 fulvous, the suture and a transverse band at the middle black. 



Length 3 lines. 



Head very sparingly and finely punctured, deeply transversely 

 grooved between the eyes ; frontal tubercles as well as the carina 

 strongly raised. Antennss half the length of the body ( 5 ), 

 filiform, black. Thorax square-shaped, the sides slightly rounded, 

 posterior margin distinctly concave at the middle ; surface somewhat 

 convex, without any depressions, fulvous, finely granulose punctate. 

 Scutellum piceous. Elytra widened from the base to the apex, very 

 convex at their posterior half, and from there to the apex abruptly 

 declined ; surface closely and finely granulose-punctate, fulvous ; a 

 longitudinal band at the suture, gradually narrowed near the apex, 

 and a transverse band below the middle, not quite extending to the 

 lateral margin, black ; from the shoulder to below the middle a 

 single costa is seen at each elytron. Underside and legs black, 

 finely covered with yellowish pubescence. Abdomen fulvous, the 

 first segments more or less stained with black. 



Hah. Africa, Transvaal. 



A single female specimen is contained in my collection. 



6. Megalognatha unifasciata, sp. nov, (Plate XLV. fig. 8.) 



Black. Antennae in the male triangularly widened at the seventh 

 and eighth joints ; in the female simple. Thorax and the elytra 

 closely punctured ; the latter flavous, with a broad transverse band 

 below the middle. 



Length 2i-2| lines. 



Head impunctate, the lower part projecting ; labrum obscure 

 testaceous. Antennae half the length of the body, black ; the 

 terminal joints testaceous at their inner sides ; the seventh and 

 eighth joints flattened and with an angular projection within, rest 

 of the terminal joints less flattened. Thorax square-shaped, the 

 space below the anterior margin raised into a triangular-shaped 

 elevation ; rest of the surface finely punctured in the male, more 

 strongly granulose-punctate in the female. Scutellum black. Elytra 

 punctured as in the preceding species, testaceous or flavous, with a 

 broad transverse black band below the middle, which does not quite 

 extend to the lateral margin. Underside and legs black ; abdomen 

 fulvous. 



Hab. Transvaal. Collection Jacoby. 



Distinguished from M. cavicoUis, Baly, by the shape and colour of 

 its thorax. 



7. Megalognatha bipunctata, sp. nov. (Plate XLV. fig. 9.) 



Elongate, convex, subparallel, fulvous ; antennae, legs, and breast 

 obscure piceous ; thorax and elytra finely punctured, a spot at the 

 middle of each elytron black. 



Length 4 lines. 



Head impunctate. Antennae very closely approached in the 

 male, the seventh and eighth joints in the same sex triangularly
