1900.] FROM SOUTH AND CENTRAL AFRICA. 229 



Length 5 milliin. 



Head finely punctured, the interstices minutely granulate, the 

 sides at the base of the antenna? raised in shape of a ridge ; antenna? 

 filiform, black, the basal three joints more or less fulvous, the first 

 joint metallic blue above, third joint but slightly longer than the 

 second but shorter than the fourth, the following joints slightly 

 thickened ; thorax twice as broad as long, slightly narrowed 

 anteriorly, the sides strongly rounded, with a narrow margin, the 

 anterior angles produced into a short tooth, the surface very finely 

 and rather closely punctured and minutely granulate ; scutellum 

 subquadrate, truncate at the apex ; elytra subcylindrical, much 

 more strongly punctured than the thorax, the punctuation arranged 

 in closely approached rows, the interstices with a few minute 

 punctures here and there, dark violaceous blue, the sutural margin 

 greenish ; below and the legs dark metallic blue, finely pubescent, 

 the anterior femora with a very minute, the posterior with a more 

 distinct tooth ; presternum widened at the base, the anterior 

 margin of the thoracic episternum concave. 



Hah. Salisbury, Mashonaland (G. Marshall). 



Allied to 0. discolor Lefev., but in that species the labrum, palpi, 

 antenna?, and the legs are brown and the thorax is described as 

 densely punctured ; the present insect, on account of the concave 

 margin of the thoracic episternum, the entire tibia?, appendiculate 

 claws, and other details, possesses all the characters peculiar to the 

 genus. 



Lefevrea brunnea, sp. n. 



Entirely pale fulvous, the head and thorax rather strongly and 

 closely punctured ; elytra closely punctate-striate, the punctures 

 very fine towards the apex. 



Length 3 millim. 



Of the general shape of a small species of Qolaspis ; the head 

 finely punctured on each side, the clypeus contiguous with the face, 

 its anterior margin moderately emarginate in the middle and on 

 each side, its surface sparingly punctured ; antenna? extending to 

 about the middle of the elytra, fulvous, the intermediate joints 

 sometimes stained with fuscous, the third and fourth joints equal, 

 one half longer than the second joint, terminal ones slightly thick- 

 ened ; thorax twice as broad as long, the sides rounded, the anterior 

 and posterior margins straight, of equal width, the angles acute, 

 the surface closely and somewhat strongly punctured, the punctures 

 more crowded at the sides, the latter with an obsolete depression, 

 scutellum with the sides rounded ; elytra not wider at the base 

 than the thorax, convex, punctured in closely approached rows, the 

 punctures themselves scarcely larger than those of the thorax ; below 

 and the legs fulvous, the latter unarmed ; claws appendiculate ; 

 prosternum strongly narrowed between the coxae. 



Hah. Salisbury, Mashonaland (G. Marshall). 



Distinct from all its allies in the uniform pale fulvous 

 coloration.
