46 Mr. Q. N. Barker on new 



Head : male steely, female greenish blue, coarsely j)uiie- 

 tate ; labriim, pal})!, first three joints and base of fourth of 

 anteniue, and tbo legs (paler) flavescent ; remaiuinj; joints 

 of antenn;e black ; terminals of palpi, kiujcs, ajjiccs of 

 tibiie, and, more or less, tlie posterior and inttnnicdiate tarsi 

 ringed with fuscous. 



Prothorax deep brick-red, cordiform, nearly twice as wide 

 at apex as at base, frontal angles declivous, moderately 

 sharp, sides broadly rounded, bordcj-ed and slightly re- 

 ilcxed, strongly contracted to basal angles, which arc acute 

 and a little recurved ; disc moderately convex, densely ru- 

 gosely punctate and very brieliy pubescent, median line fine 

 but distinct. 



Elytra opaque black, briefly [)ubesceut, oblong-ovate, base 

 and shoulders declivous, the latter broadly rounded, finely 

 punctate-striate, a little more deeply about the ai)ical 

 declivity, intervals plane, finely shagreen-punctate;, narrowly 

 or not flavescent margined, and with, on either side, two 

 transverse bauds or fascial, a small postiuedian juxta- 

 sutural and a sutural apical, spot. 



The anterior band is very sinuate — that is to say, it 

 projects above and below on the alternate intervals and 

 extends, gradually ^videning from the third stria to the 

 outer margin. 



The postiuedian transverse hand is liardly sinuate; it 

 covers the intervals 4 to 7, and is obscurely defined 

 beyond to the edge of the outer margin. Tlie postniediaa 

 jnxta-sutural spot is situated a little above the postmediau 

 band on the second and third intervals, and the apical 

 sutural spot is triangular in shape. My male example has 

 tlie elytra narrowly margined with flavous, but this is wanting 

 in the female example, except for a short distance above 

 and below the anterior transverse band. 



The pectus, abdomen, and the centre line of the pro- 

 sternum piceous. 



From C. differ, Boh., dicersus is differentiated by the 

 coloration of head, prosternum, pectus, and abdomen ; by 

 the situation of the postiuedian juxta-sutural spot which is 

 well above the postmedian band, whereas in caffer it is in 

 line with and usually connected with it by a somewhat 

 obscurely defined spot on the fourth interval. 



It is considerably smaller, the pnncturation of head 

 coarser, the prothorax laterally much more constricted 

 towards base, the elytra more shortly ovate. 



It is much more nearly related to C. stx-pusiulalus, Boh., 

 and is only differentiated from that species ou the following
