1112 ON THE CARENIDES, WITH DESCRIPTIONS OF NEW SPECIES, 
interioris ; the shape of the elytra also differs from that of 
C. campestris in not being narrowed at the base. In C. campestris 
and its allies there are three marginal punctures on each side of 
the prothorax, but in my single example of Chariscapterus opulens 
there appears to be but one marginal punctui’e on each side, viz., 
that at the posterior angle ; this I believe not to be a constant 
character, the normal number will probably be found to be two on 
each side, at the anterior and posterior angles. 
Carenum cupreo-inarginatum, Blackburn, will come into this 
sub-genus, as will probably C. porphyreum, Bates, and possibly 
C. hreviforme, Bates. 
Chariscapterus opulens, sp.nov. 
Nitidus, Isevis, elytris viridi-micantibus ; capite magno, sub- 
quadrato, supra oculos unipunctato, ad clypeum baud punctigevo, 
sulcis frontalibus parallelis, antice fortiter divergentibus ; 
thorace ad latera aeneo, margine cupreo, late transverse, antice 
truncate, angulis anticis productis, postice sinuato, marginato, 
leviter canaliculate ; elytris margine splendide cupreo, prothoraci 
latitudine aequalibus, late reflexo-marginatis, antice truncatis, 
sutura leviter impressa, postice bipunctatis ; tihiis anticis triden- 
tatis, infra tarsos apice dente longiusculo armato. 
Long. 21 mm., lat. 7 mm. 
Under parts, head, and disc of thorax black, elytra bright 
metallic green, thorax and elytra with vivid cupreous margin. 
Head large, square (4^ x 5|), smooth, with one supra-orbital 
puncture on each side ; the frontal sulci parallel, in front turning 
sharply outwards. The frontal puncture, which is almost 
invariably present among the Carenides between the out-turned 
frontal groove and the clypeus on each side, is wanting in the 
present species. Prothorax convex, widely transverse (4|- x 7), 
with wide reflexed margin along the .sides and base ; truncate in 
front, with the anterior angles obtuse, and considerably advanced; 
shortly rounded at the posterior angles and sinuate behind, the 
base being lightly emarginate ; the median line distinct. Only
