238 MI<> M. JACOB Y ON PHYTOPHAGOUS COLEOPTERA [Mar. 6» 



RlMERIDA CHAPTJTSI, sp. U. 



Oblong-ovate, convex, below aeneous, clothed with white 

 pubescence : above obscure cupreous, covered with white and 

 Fulvous scales, forming transverse bands : antenna 1 blade : femora 

 armed with a sti'ong tooth. 

 , Length 4| millim. 



Head broad, covered with white and piceous scales, through 

 which cupreous patches can here and there be distinguished, 

 sparingly punctured, anterior edge of the clypeus deeply eruar- 

 ginate, labrum fulvous, palpi piceous ; antennae not extending much 

 below the base of the thorax, black, the basal joint subquadrately 

 thickened, the following four joints equal, the terminal five 

 strongly widened ; thorax rather more than twice as broad as long, 

 the lateral margins distinct at the base only, the median lobe 

 moderately produced, the disc convex - , exactly similarly covered 

 with scales as the head, their colour white and dark brown ; 

 scutellum densely clothed with white scales, much broader than 

 long, pentagonal ; elytra very slightly wider than the thorax, 

 similarly provided with scales, these forming three more or less 

 distinct transverse irregular bands and more densely white patches 

 at the sides and at the apex ; legs piceous, clothed with white 

 scales ; below densely clothed with white pubesceuce, the ground- 

 colour (where visible) cupreous; presternum much broader than 

 long, claws bifid. 



Huh. Salisbury, Mashonaland, on mimosa ((?. Marshall ). 



The general broadly ovate shape of this insect, its scale-like 

 pubescence, the thickened terminal joints of the antennae, concave 

 anterior margin of the thoracic episternum, &c. seem to me to 

 place this species in Chapuis's genus Himera, changed later by 

 Lefevre to Himerida. The only species of the genus, of which a 

 two-line description is given by the author, seems closely allied 

 to the present one, and it is just possible that the latter is identical 

 with the type ; but Chapuis gives the basal joints of the antennae 

 as ferruginous, which is not the case in the four specimens 

 before me, and says nothing of white scales forming bands, 

 although the latter are sometimes very indistinct ; the inner 

 divisions of the claws are very small. 



Odoxtiomorpha, gen. nov. 



Body ovately subquadrate, glabrous above ; antenna? with 

 widened terminal joints ; thorax transverse, with a distinct trans- 

 verse sulcus ; elytra convex, punctured in semiregular rows ; 

 femora with a very minute tooth, the intermediate tibia? emarginate 

 at the apex ; tarsi short, triangular ; claws appendiculate ; pro- 

 sternum broad, subquadrate, its base truncate ; the anterior 

 margin of the thoracic episternum concave. 



The only group, according to Lefcvre's or Chapuis's arrangement, 

 which the present small species could enter would be the Orfon- 

 tionopina 1 , which contains at present three genera, all inhabiting
