264 ME. M. JACOBT ON THE [Feb. 2, 



sutural, basal, and the lateral margin posterioi'ly black, below the 

 base four black spots of irregular shape are placed in an oblique 

 quadrate position, of these, one is situated on the shoulder, the 

 other directly below it, the other two between the lateral spots 

 and the suture, also below each other, occupying the third and 

 fourth and the fifth, sixth, and seventh interstices respectively, 

 the A-shaped marked is placed below the middle near the lateral 

 margin and is sometimes divided into two irregular spots ; pygi- 

 dium fulvous, finely pubescent ; underside and legs of the same 

 colour ; the sides of the breast and a spot on the upper portion of 

 the femora blackish. 



Hah. Natal, Estcourt ((?. Marshall). 



In the markings of the thorax this species resembles C. denti- 

 culatus, Suffr., of which it may possibly be an extreme variety ; I 

 have, however, two specimens before me which almost entirely 

 agree with each other, and in these the elytral markings are quite 

 different from the above-named species, especially in the very 

 narrow black sutural and lateral margin (the last of which com- 

 mences at the middle only). Sufl'rian also speaks of finely wrinkled 

 and punctured elytral interstices, of which there is no trace in the 

 present insect. 



CCENOBIUS FLATITAKSIS, n. Sp. 



Black, shining, the basal joints of the antennae, the apex of the 

 tibiae, and the tarsi flavous ; thorax strongly punctured ; elytra 

 very strongly punctate-striate, the interstices longitudinally 

 costate at the sides. 



Length f line. 



Head black ; the entire vertex and the sides occupied by the 

 eyes, which meet at the top ; antennae extending a little beyond 

 the base of the thorax, black, the basal five joints flavous, third 

 and fourth joint very small, terminal joints distinctly widened ; 

 thorax about one-half broader than long, the sides nearly straight 

 and much narrowed anteriorly, the surface with a deep transverse 

 oblique groove at each side, strongly and rather closely punctured, 

 the punctures somewhat oblong in shape, the basal margin with a 

 row of deep and closely placed punctures ; scutellum narrowly 

 elongate ; elytra with very deep and close rows of punctures, the 

 shoulders very prominent, the basal margin in shape of a ridge, 

 the interstices longitudinally costate, more strongly so at the sides 

 than at the disc : the underside, pygidium, and the legs black, 

 the extreme apex of the tibiae and the tarsi flavous. 



Hab. Mashonaland (G. Marshall). A single specimen in the 

 British Museum collection. 



Allied to C. nigritellus, Suffr., but at once distinguished by the 

 flavous tarsi and the sculpturing of the thorax &c. C. suffriani, 

 Jac, has the head strigose at the vertex, the antennae scarcely 

 widened, the thorax without lateral depressions, and the tarsi black. 



Chi/AMTS natalensis, n. sp. 



Obscure fulvous or piceous ; the antennae and the tibiae fulvous .
