1900.] FROM SOUTH AND CENTRAL AFRICA. 215 



basal margin very narrowly, a spot on the shoulders, another near 

 the suture at the middle, and a narrow transverse irregular-shaped 

 band near the apex black, the extreme lateral margin posteriorly 

 dark fulvous ; below and the legs flavous ; abdomen darker ; the 

 anterior legs rather elongate, their tarsi very broad. 



Hob. Delagoa Bay (G. Marshall). 



Of this species I received three specimens from Mr. Marshall 

 which show no differences of any importance. There are not manv 

 African species of the present genus which have a similarly marked 

 thorax, the nearest being perhaps 0. denticulatus ; in the present 

 species, however, the dark portion of the thorax is not black but 

 dark fulvous or piceous ; the number and position of the elytral 

 spots also differ from any of its allies. 



Cryptocephaltjs severini, sp. n. 



Black, above and the legs flavous, vertex of head black ; thorax 

 impunctate, with five black stripes ; elytra finely and irregularly 

 punctured, with a subsutural and lateral black longitudinal band, 

 the latter divided. 



Length 8 millim. 



Broad and robust ; the head impunctate, slightly depressed, 

 flavous, the vertex with a narrow transverse black band ; eyes 

 very broadly emarginate ; clypeus concave at its anterior margin ; 

 antennae not extending to the middle of the elytra, flavous, the 

 terminal five joints widened ; thorax subcylindrical, with strongly 

 deflexed sides, the middle widened, the surface entirely impunctate, 

 flavous, with five equally distant black spots or bands, the middle 

 one narrow and extending from the base to the apex, the others 

 much shorter and abbreviated at each end, the outer one the 

 shortest and placed on the lateral margin ; scutellum black, broad, 

 its apex truncate; elytra not wider at the base than the thorax, 

 slightly constricted at the sides near the middle, the puuctuarion 

 very fine, placed in double rows near the suture, but irregularly at 

 the sides, the last row placed at some distance from the lateral 

 margin, the latter likewise accompanied by a stronger row of 

 punctures ; each elytron with two longitudinal black bands, the first 

 placed near the suture of slightly oblique direction, abbreviated 

 below the middle, the other placed on the shoulder, interrupted at 

 the middle and not extending much further than the subsutural 

 band ; underside black, clothed with very short pubescence, the 

 coxte and the last abdominal segment flavous at the base ; pygidium 

 flavous with a central black spot ; presternum broad, pubescent, 

 its base produced at the angles into a blunt point. 



Hah. Loulouabourg, Congo. (Coil. Belgian Mns. and my own.) 



One of the largest African spacies, and easily recognized by the 

 system of its coloration. 



Cryptocephalus strigicollis, sp. n. 



Obscure fulvous; antennae (the basal joints excepted) black; 

 thorax fulvous, closely longitudinally strigose ; elytra strongly
