concave, the sides with a raised margin ; pygidium fulvous \vith a 

 black patch at the middle. 



Hah. Assiaie, W. Coast of Africa {Ch. Alluaud). 



Likewise allied in coloration to C. vittiget; Suffr., C. jucundus, 

 Dohrn, but differing in the colour of the thorax, scutellum, &c. 

 The amount of black and yellow is very variable, the bands of the 

 thorax and elytra differing much in their width ; in the variety there 

 are only four yellow gpots present on the el}-tra, indicating the 

 bands, and it is probable that the other extreme in which the 

 yellow predominates may be found : the small subquadrate yellow 

 spot in front of the scutellum is a good mark of recognition 

 in this species. 



Cbtptocephalus pobicollis, n. sp. 



Dark brown ; antennae and legs flavous ; thorax deeply 

 pmictured and longitudinally strigose, the margins and two spots 

 flavous ; elytra deeply punctate-sti'iate, the interstices costate, 

 flavous, an obscure transverse band before, another below the 

 middle, and the apex dark brown. 



Length 1 line. 



Head with a few punctures at the vertex and round the eyes, 

 the former brown, the latter closely approached at the top, the 

 intermediate space and the clypeus flavous ; antennae nearly ex- 

 tending to the middle of the elytra, flavous, the basal joint much 

 thickened, the second short, the third and fourth equal, slender, 

 the terminal joints more elongate, slightly thickened ; thorax twice 

 as broad as long, the lateral margin straight, narrowed towards the 

 apex, the surface very closely and deeply punctured, the punctures 

 rather more widely placed near the base, the interstices everywhere 

 lougitudinally raised and obliquely directed towards the base, dark 

 brown, the anterior and lateral margins, the former very narrowh", 

 and two round spots near the base, flavous, extreme basal margin 

 black ; scutellum triangular, its apex raised ; . elytra subeylindrical, 

 the punctured strije deeply placed, all the interstices strongly 

 costate, flavous, tliis colour interrupted by two obscure transverse 

 brown bands before and below the middle, the second band is 

 generally widened near tlie suture, the apices are likewise more less 

 brown ; the underside is sparingly punctured, dark brown ; the pro- 

 sternum is broad and widened towards the base, finely punctured. 



Bab, Madagascar, Diego-Suarez (Ch. Alluftucl). 



A pretty little species, mtich distinguished liy the sculpture of 

 the thorax, and evidentlj- closely allied to several other Madagascar 

 species described by the late Duvivier, having the elytra similarly 

 strongly costate ; in none of these, however, is the thorax coarsely 

 punctured and strigose. 



Cetptoceph.u-us aematus, n. sp. 



Black ; the clypeus, basal joints of the antennae, and the legs 

 flavous ; thorax finely and closely pvmctm*ed, flavous with two 

 large black spots ; elytra strongly punctate-striate, the interstices
