250 MB. M. JACOBY ON PHYTOPHAGOUS COLEOPTEBA [Mar. 6, 



C. chalcoptera by the finely punctured and granulate upper surface 

 and the entirely unicolorous blue elytra. Mr. Marshall has sent 

 me three specimens of it. 



Chibodica pulvicobnis, sp. n. 



Narrowly elongate, black, the antenna; fulvous, the head, thorax, 

 and legs flavous ; thorax impunctate, the sides rounded ; elytra 

 closely and finely punctured, black. 



Length 21 millim. 



Head impunctate, strongly obliquely grooved above the eyes ; 

 frontal elevations broad and flattened, apex of the clypeus between 

 the antennas rather broad, palpi distinctly thickened ; antenna? 

 extending to the base of the elytra, entirely fulvous, all the joints, 

 with the exception of the first, short, the terminal ones thickened ; 

 thorax one-half broader than long, the sides rounded, the angles 

 distinct, very slightly thickened, the surface entirely impunctate ; 

 scutellum black, impunctate; elytra slightly wider at the base than 

 the thorax, very feebly depressed below the' base and the scutellum, 

 black, shiny, finely, closely, and evenly punctured : legs rather 

 robust, flavous ; breast and abdomen black ; the last abdominal seg- 

 ment with a round fovea ( <J ?) ; presternum very narrow, anterior 

 coxal cavities open. 



Hab. West Africa. 



Closely allied to C. wollastoni Baly, but with the antenna? 

 entirely fulvous and the sides of the thorax rounded, not straight. 



Jamesonia (Theymnes) femoealis, sp. n. (Plate XX. fig. 12.) 



Oblong, the head, antenna? (excepting the basal joints), the 

 breast and abdomen, and the posterior legs black ; thorax fulvous, 

 impunctate ; elytra violaceous blue, very minutely aud closely 

 punctured ; base of posterior femora fulvous. 



Length 4 millim. 



Head black, impunctate, the frontal elevations trigonate, oblique ; 

 clypeus with a long and acutely raised central ridge ; palpi black ; 

 antenna? extending to about the middle of the elytra, black, the 

 lower four joints fulvous, third and fourth joints equal, each one- 

 half longer than the second, following joints more elongate ; 

 thorax one-half broader than long, slightly narrowed anteriorly, 

 the sides and the posterior angles rounded, anterior angles oblique, 

 the surface microscopically punctured, fulvous ; scutellum triangular, 

 black ; elytra wider at the base than the thorax, elongate, convex, 

 metallic bluish or violaceous, extremely finely and closely punctured ; 

 legs fulvous, the apex of the posterior femora, their tibia? and the 

 tarsi blackish, posterior tibia? with a long spine; presternum 

 extremelv narrow, anterior coxal cavities open. 



Hab. Port Alfred, South Africa {Rev. J. O'Neil). 



Differing entirely in coloration from the other species of the 

 genus described by Weise and myself. I received eight specimens 

 from the Eev. J. O'Neil.
