extending to the second row of punctures, the lateral bands occu- 

 pying four rows of punctures but of the same width as the sutural 

 band, with the margins more regular and less dentate than in the 

 last named, the lateral margin also more or less black posteriorly ; 

 underside black, more or less marked with flavous ; legs flavous, 

 the femora often partly black or fulvous ; prosternum broad, flavous, 

 impunctate ; pygidium black, its apex more or less fulvous. 



Hah. Natal, Estcourt (&'. Marshall). 



A pretty species alhed to C, vittiger, Suffr., and 0. contrarius, 

 Chap., in coloration, but differing in the closely punctured head and 

 the pale margins or stripes surrounding the eyes, and in the yellow 

 clypeus : the stripes of the elytra are also differently shaped ; but 

 the amount of black at the underside and of the thorax is very 

 variable, in one specimen the black bands of the latter are nearly 

 united at the middle by a narrow transverse streak, leaving a 

 fulvous patch at the base which is again divided by a central short 

 narrow streak of piceous ; the antenuje are also variable in colour. 

 C. vittiger has an entirely black head, the elytral bands are differ- 

 ently shaped, and the underside also varies. 



Cbyptocephaltjs alluatidi, n. sp. 



Black and yellow ; head with two fulvous spots on the vertex ; 

 thorax impunctate, black, the sides, anterior margin, and a spot at 

 the base yellow ; elytra strongly punctate-striate, black, a narrow 

 sutural and a broad lateral band yellow ; legs flavous. 



Var. Elytra black, the shoulders and the apex with a short 

 yellow spot. 



Length 1 line. 



Of posteriorly slightly narrowed shape ; the head rather closely 

 punctured at the middle, black, the vertex with two obscure 

 fulvous spots ; the clypeus, a narrow space in front of the ej^es, 

 and the labrum yellow ; antennae extending slightly beyond the 

 middle of the elytra, the lower five joints flavous, the others black, 

 the basal joint much thickened, the third and fourth equal, the 

 terminal joints gradually but rather strongly incrassate ; thorax 

 twice as broad as long, sti-ongly narrowed in front, the sides 

 straight or verj^ nearly so, with a narrow reflexed margin, the 

 angles not prominent, the surface Jiearly iuipunctate, a few scarcely 

 perceptible punctures only being visible under a strong lens, black, 

 the antei'ior margin narrowly, a broad band at the sides and a 

 square-shaped spot in front of the scutellum yellow ; scutellum 

 rather broad, its apex truncate, yellow, narrowly margined with 

 black ; elytra narrowed posteriorly, with deep rows of punctures, 

 distinct to the apex, the interstices slightly transvei-sely wrinkled 

 here and there, the colour black, a narrow, anteriorly widened 

 sutural stripe, not extending to the apex, and a broad band at the 

 sides not extending to the margios nor to the apex, but of variable 

 width, yellow ; underside finely pubescent, black ; the prosternum, 

 mesosternum, the last abdominal segment, and the legs flavous, the 

 latter rather darker; prosternum subquadrate, its base slightly
