1900.] FROM SOUTH AND CENTRAL AFRICA. 263 



the sides feebly rounded at the middle, the angles distinct but not 

 produced, the basal margin but slightly rounded, the surface 

 entirely impunctate ; scutellum triangular, fuscous ; elytra with 

 their greatest width below the middle, wider at the base than the 

 thorax, the surface with some very minute punctures, only visible 

 under a very strong lens ; below black or piceous, the femora 

 flavous, the tibiae and tarsi black, all the tibiae mucronate ; the 

 metatarsus of the posterior legs as long as the following three 

 joints together ; elytral epipleura? continued below the middle. 



Bab. Port Alfred, South Africa (Rev. J. ffNeil). 



Amongst the unicolorous or for the most part fiavous species of 

 this genus known from Africa, the present one seems most nearly 

 allied to O. mashonana Jac, but is only half the size of that 

 species, which has also a flavous underside, and the metatarsus of 

 the posterior legs much longer ; O. nigrotibialis Jac. is likewise 

 larger, and the lower joints of the antennas as well as the under- 

 side are flavous and the elytra distinctly punctured ; in several 

 other species the tibia? and tarsi are flavous. I dedicate this 

 species to the Rev. J. O'Neil, in recognition of his constant 

 endeavours to explore the entomological fauna of his district. 



Candezea livingstonii, sp. n. 



Pale flavous or testaceous, the apical joints of the antenna? and 

 the breast black ; thorax finely punctured, obsoletely sulcate; elytra 

 very finely and closely punctured. 



Length 3 millim. 



Head rather broad, impunctate ; clypeus strongly thickened, 

 bounded behind by a deep transverse groove ; antenna? extending 

 to the middle of the elytra, the lower four or five joints flavous, 

 the rest black, the second and third joints equal, short, the fourth 

 doublethe length and equal to the following joints; thorax transverse, 

 twice as broad as long, the sides very feebly rounded at the middle, 

 the posterior margin rounded, the surface with a shallow transverse 

 sulcus at the middle, finely and closely punctured ; elytra wider at 

 the base than the thorax, extremely closely and finely punctured, 

 the interstices somewhat wrinkled, their epipleurae very narrow 

 below the middle ; legs flavous, all the tibia? armed with a spine, 

 the metatarsus of the posterior legs very elongate ; the breast black. 



Hob. Salisbury, Mashonaland, obtained by sweeping (G. Mar- 

 shall). 



One of the small species of the genus, distinguished by the 

 transverse sulcus of the thorax and the black breast. 



Sardoides nigricornis, sp. n. 



Dark metallic blue, the antenna? black ; thorax with a deep trans- 

 verse sulcus ; elytra navous, finely punctured, the sutural and lateral 

 margins metallic blue. 



Length 5-6 millim. 



S . Elongate and parallel, dark metallic blue ; the head impunc- 

 tate, the frontal elevations strongly raised, trigonate, the carina
