182 M. Louis Peringuey on new genera and species of 



■what bi-jjlicate ; both head and prothorax are clothed with a slightly 

 ochraceous pubescence ; scutellum transverse, sub-quadrate ; elytra 

 sub-parallel, a little broader at the base than the prothorax across the 

 median part, sinuate laterally at the base in such a way as to make the 

 humeral angle very prominent, a little attenuate gradually towards 

 the apex, convex, closely punctured, and covered with a very fine, 

 short, slightly greyish pubescence, sprinkled with minute light 

 ochraceous or whitish spots, and having also two broader ones at 

 the base on each side of the scutellum ; underside and legs densely 

 pubescent ; the 4th joint of the antennae is slightly constricted near 

 the apex, and all the joints are pubescent and ringed with brown 

 at the tip from the fourth to the last one. The 5 has no trace of 

 the frontal process. Length 21-22, width 7i-8 mm. 



Hah. Mozambique (Rikatla) ; Transvaal. 



In the examples from Rikatla the white speckles on 

 the elytra are much more conspicuous than in those from 

 the Transvaal. 



Gen. Tragocephala, Cast. 



T. riliatlfe, n. sp. 



Densely covered with a very short black velvety pubescence ; 

 antennae and legs velvety-black ; head and prothorax bright 

 sulphur-yellow, the latter with a narrow median longitudinal black 

 band reaching from the base to the apex, the lateral part of 

 the prothorax aculeate in the middle ; elytra as broad as the 

 prothorax in the median part, a little attenuated behind, depressed, 

 and with four broad transverse bands on each side edged with 

 white, separated by a narrow band of the black ground-colour and 

 reaching from the outer margins to near the suture, but discon- 

 nected from it ; the first, second and fourth bands are of nearly 

 equal breadth, but the third one is narrower and divided in 

 two at about the median part by a diagonal narrow black line ; 

 underside with a broad bright yellow lateral band running from 

 the sides of the mesosternum to the apex ; legs bright yellow. 

 Length 15, width 5 mm. 



Hah. Mozambique (Rikatla). 



At once distinguished from the other South African 

 species by the narrow black median line of the prothorax, 

 and the very broad yellow bands of the elytra, which 

 have very nearly invaded the whole of the surface.
