The sculpturing of this species is quite exceptional amongst the 

 African representatives of the genus, but it approaches in that 

 respect, as well as in colouring, 6'. ^mamydidus, Fabr. ; but 

 the present species has entirely black antennae, rounded shoulders, 

 and the arrangement of the punctures in rows can only be seen in 

 certain hghts, as they are so closely approached and having the 

 interstices nearly as strongly punctured. 



Cetptocephaltjs teisulcatiis, Suffr. 



Black, clypeus white ; thorax and elytra fulvous, the former with 

 two oblique black bands ; elytra moderately strongly punctured, a 

 spot on the shoulder and two others, obliquely-transverse, near the 

 apex black ; femora black and white. 



Var. Thorax with four black spots, elytra without any spots. 



Length 2 lines. 



Head black, very finely punctured at the vertex ; the clypeus 

 and the sides below the eyes yellowish white ; antennae slender, 

 black, the lower five joints testaceous, the third joint one-half 

 longer than the second, the foiu'th shorter than the fifth joint, 

 terminal joints elongate in the male, shorter in the other sex ; 

 thorax strongly narro\^ed in fi-ont, the sides evenly rounded, 

 posterior margin bisinuate at the sides, the surface nearly impunc- 

 tate, fulvous, the posterior angles flavous, all the margins narrowly 

 black, the middle of the disc with two oblique longitudinal bands, 

 ]iot extending to the apex, and scarcely to the base ; scutellum 

 black ; elytra rather finely punctate-striate near the suture, the 

 punctures nearly obsolete at the base, the sides more stronglj' and 

 closely punctured, with the interstices slightly convex, the lateral 

 margins posteriorly as well as the apical ones narrowh- black, a 

 black spot is placed on the shoulder and two others near the apex, 

 of these one is situated across the suture, the other rather larger 

 one near the lateral margin and a little higher than the sutural 

 spot; underside and the femora black, the anterior femora with 

 their lower surface nearly white ; tibiae fulvous, or stained with 

 piceous at the apex ; prosternum with two small teeth at its base, 

 yellowish white, as well as the mesosternum and the space between 

 the posterior coxse, the entire imderside nearly impunctate.

The position of the elytral spots differs from that of any other 

 African species except C. eri/t/iromelas with which I am acquainted, 

 and the white clypeus, prosternum, and bicolored anterior femora 

 are likewise characteristic of the present insect. The variety differs 

 in no way from the type except in the absence of the elytral spots 

 and in the breaking up into four spots of the thoracic bands ; the 

 former are placed quadrately, thus indicating the oblique shape of 

 the bands in the normal form, marking their commencement and end. 



I have given here a new description of Suffriau's species, with 

 which the present insect agrees so closely that I must identify it 

 with it, although the specimens before me are smaller than the size 

 given by Suffrian; this author had also probably old specimens
