1900.] FROM SOUTH AND CENTRAL AFRICA. 225 



Pseudocolaspis cupreofemorata, sp. n. (Plate XX. fig. 4.) 



Violaceous-blue, the antennae, tibiae, and tarsi black ; the femora 

 cupreous ; thorax subclyindrical, closely and strongly punctured ; 

 elytra punctured like the thorax, with rows of very short, white 

 hairs, distantly placed. 



Length 4 millim. 



Head coarsely and closely punctured, dark blue ; the antennas 

 entirely black, the terminal five joints strongly dilated, club-shaped ; 

 thorax scarcely broader than long, narrowed anteriorly and to 

 a less extent near the base ; the entire surface closely and strongly 

 punctured, the punctures round and deep, the middle with a more 

 or less distinct narrow, raised longitudinal space ; scutellum 

 subquadrate, its apex truncate, the posterior angles feebly pro- 

 duced, the base with two or three deep punctures ; elytra with 

 the shoulders prominent and acute, not depressed below the base, 

 punctured like the thorax, but the punctures rather more closely 

 placed and the interstices finely transversely rugose, sparingly 

 furnished with very short stiff whitish hairs ; legs coarsely punc- 

 tured ; the femora with a strong acute tooth, cupreous ; the 

 intermediate tibiae, with the exception of the extreme apex which 

 is more or less cupreous, black ; claw- joint very long and slender. 



Hah. Salisbury, Mashonaland, obtained by sweeping (G. 

 Marshall). 



Distinct from all its numerous African allies by its uniform 

 dark blue colour and the cupreous femora, in connection with the 

 strong punctation of its upper surface. 



Pseudocolaspis severini, sp. n. 



Black, sparingly pubescent, thorax finely and closely punctured ; 

 elytra finely punctured in semiregular rows near the apex, the 

 interstices clothed with very short, erect, silvery hairs. 



Length 4 millim. 



Head closely and rather strongly punctured; clypeus broad, 

 subquadrate, scarcely punctured ; antennae black, the lower four 

 or five joints more or less piceous ; the second and the following 

 two joints very short, moniliform, the terminal ones strongly 

 thickened and robust, the last longer than broad ; thorax rather 

 long, subcylindrical, but slightly narrowed in front, the surface 

 without any perceptible sulci or depressions, closely and strongly 

 punctured, with a smooth narrow middle line ; scutellum broad, 

 subpentagonal, irapunctate; elytra narrowed posteriorly, not 

 depressed below the base, the shoulders prominent, the surface 

 closely, finely, and irregularly punctured, the punctures slightly 

 more regularly arranged in rows near the apex ; the interstices 

 with single short silvery pubescence ; femora with a small tooth ; 

 underside and legs rather strongly punctured.
