Jamesonia nigrifennis, sp. n. 



Black, the lower portion of the face and the thorax reddish 

 fulvous, the latter very minutely punctured ; elytra opaque, black, 

 closely and more distinctly punctured than the thorax; legs 

 black.

Head broad, impunctate, the vertex black, the lower portion in 

 shape of a large subquadrate patch, fulvous, frontal elevations very 

 broad ; carina rather blunt, anterior edge of the clypeus straight ; 

 antennae robust, extending to about the middle of the elytra, black, 

 the second and third joint small, equal, third and following joints 

 thickened, about twice as long as broad ; thorax twice as broad as 

 long, convex, the sides rounded, the posterior angles rather oblique, 

 the surface extremely minutely punctured, reddish fulvous ; scu- 

 tellum black ; elytra slightly broader at the base than the thorax, 

 very slightly narrowed posteriorly, black, opaque, closely and fin el y

Hah. Dunbrody, Cape Colony (Eev. J. (JNeil). 



Distinguished by the opaque black elytra, antennae, and legs, 

 and the colour of the head ; the eyes in this species are, however, 

 much more distantly placed than in the other members of the genus, 

 and the posterior angles of the thorax are less rounded : all other 

 characters agree with the typical species. 



Decaria obsctjra, sp. n. 



Below and the legs pale fulvous, above obscure dark fulvous, 

 antennae (the basal joints excepted) black ; thorax extremely 

 minutely, elytra more distinctly punctured, the punctures arrauged 

 in very close semiregular rows ; antennae ten-jointed. 



Length 2 millim. 



Head impunctate, obscure fulvous or piceous, frontal elevations 

 transverse, broad ; carina distinct ; antennae closely approached at 

 the base, black, the lower two joints fulvous, second joint very 

 small, third and following joints triangularly dilated, rather broad 

 and robust ; thorax scarcely twice as broad as long, the sides 

 rounded, the anterior angles slightly obliquely thickened, basal 

 margin distinctly concave in front of the scutellum, the disc obscure 

 dark fulvous, with a few minute punctures ; scutellum broad, im- 

 punctate ; elytra distinctly wider at the base than the thorax, 

 slightly widened towards the middle and gradually narrowed 

 posteriorly, the apex rounded, the surface convex, subcylindrical, 

 rather strongly punctured in closely approached semiregular rows ; 

 posterior femora strongly incrassate ; posterior tibiae with a long 

 spine, their metatarsus as long as the following two joints together. 



Hob. Ehobomp, Sierra Leone. 



This cannot be D. tricolor Weise from the same locality, as the 

 author describes the antennae as yellowish brown and the elytra aa
