198 CERICHBESTUS. 



from the base of the head, extending nearly as far as the anterior 

 angles of the thorax : between the labrum and the base of the an- 

 tennae, the surface is smooth, glabrous, and transversely depressed ; 

 immediately above the base of the antennae is an obsolete longitu- 

 dinal depression; the whole surface being coarsely granulated; in 

 colour black, the space between the labrum and the antennae being 

 flavous : at the base of the head, immediately behind the eyes, are 

 two transversely lateral markings of a fulvous-red colour. Thorax 

 transverse, slightly contracted in front, and (when viewed laterally) 

 subdepressed ; the anterior angles are subacute and depressed ; the 

 sides marginate ; at the basal angles are two broad and obsolete de- 

 pressions : the surface is clothed throughout (when viewed under a 

 high power) with a short and thick pubescence ; the colour fulvous- 

 black, with a broad margin on either side of a bright golden-flavous 

 colour. Scutellum triangular, dark fuscous. Elytra somewhat 

 broader than the thorax, parallel, subelongate, deeply punctate- 

 striate, the interstice between the second and third striae being 

 slightly but distinctly elevated ; clothed throughout with a thick close 

 pubescence ; the colour black, of a ferrugineous hue ; at the shoulders 

 is a suffused flavous marking, which (becoming more obsolete) tinges 

 the anterior half of the line of margination ; the body beneath black. 

 Antennae broad, robust, dilated, and flattened medially ; the first joint 

 broad, and gradually dilated towards the apex ; the second short, sub- 

 triangular ; the third longer than, but hardly so broad as the first ; the 

 fourth to the seventh gradually but broadly dilated, and the seventh 

 to the eleventh gradually attenuated towards the apex : the colour 

 black, finely pubescent ; the ninth joint being fulvous, and the tenth 

 and eleventh flavous. Legs black; the base of the femora being 

 fulvous, or suffused with flavous ; the posterior tibiae and tarsi ful- 

 vous ; the globular inflation of the posterior claw piceous. 



This species very nearly approaches C. Balii both in disposition 

 of markings and in general form ; it is, however, shorter and broader, 

 and the thorax is unmarked by any lateral depressions.
