1899.] PHYTOPHAGOUS COLEOPTEBA OF AFRICA. 369 



Eah. Salisbury, Mashonaland, Estcourt, Natal {G. Marshall). 



Of the specimen which I consider a variety and which was 

 obtained at Natal, I have only a single example before me ; struc- 

 turally it does not seem to differ from the type, but it diverges 

 entirely in coloration. The whole under surface is black, the 

 head has two bright fulvous spots at the A-ertex, the thorax is 

 piceous, narrowly margined with fulvous, and the elytra show the 

 same colour at the base and the apex. Possibly the specimen 

 represents another species. 



Hemisantha teeminata, sp. n. (Plate XXI. fig. 6.) 



Eufous, the antennae, tibiae, and tarsi flavous ; thorax very finely 

 punctured ; elytra black, the apex rufous, punctured like the 

 thorax. 



Length 6 millim. 



Head rufous, not perceptibly punctured, the eyes very large and 

 prominent, the frontal elevations broad and subquadrate, clypeus 

 triangularly raised, labrum and palpi flavous ; antennae long and 

 slender, flavous, the terminal joints stained with black at the apex, 

 the last one entirely of this colour ; third joint one half longer 

 than the second, the following elongate, slightly curved and finely 

 pubescent ; thorax scarcely twice as broad as long, the sides* very 

 feebly rounded, very narrowly margined, the angles slightly oblique 

 and thickened, the surface very minutely and remotely punctured, 

 rufous, shining, basal margin slightly sinuate at the middle, 

 narrowly margined ; scutellum broad, rufous, longer than broad ; 

 elytra wider at the base than the thorax, distinctly depressed near 

 the suture, black, the extreme apes rufous, the surface punctured 

 like the thorax ; below and the femora reddish fulvous, the tibiae 

 and tarsi flavous ; the metatarsus of the posterior legs as long as 

 the following three joints together. 



Hah. Estcourt, Natal {Gr. Marshall). 



Hemixantha bifasciata, sp. n. (Plate XXI. fig. 7.) 



Eeddish fulvous, the antennae, tibiae, and tarsi flavous ; thorax 

 extremely finely punctured, flavous or fulvous ; elytra nearly im- 

 punctate, flavous, a narrow transverse band at" the base and 

 another below the middle, black. 



Length 6 millim. 



Head impunctate, rufous, the frontal elevations broad and sub- 

 quadrate ; eyes large and round ; antennae extending nearly to the 

 middle of the elytra, flavous, the apex of the terminal joint black 

 all the joints with the exception of the second of nearly equal 

 length ; thorax nearly twice as broad as long, the sides rounded 

 the anterior angles produced, subtuberculiform, the siu-face only 

 perceptibly punctured when seen under a very strong lens, pale 

 testaceous or fulvous, very shining ; scutellum trianguhir, flavous • 

 elytra not more distinctly punctured than the thorax, flavous, the 

 base with a narrow transverse black band extending to the sides
