Black, elytra with an olivaceous-green metallic sheen, legs piceous- 



red with the tihiae black, totally piceous-red, or entirely black, tarsi,. 



palpi and the three basal joints of antennae rufescent, the other 



antennal joints more or less deeply fuscous ; prothorax sub-cordate, 



that is to say rounded and ampliated from the anterior part to the 



median, and strongly sinuate thence to the posterior angle, posterior 



part of the disk very deeply depressed on each side of the base, the 



two posterior depressions and the sides are closely aciculato-punc- 



tate, the anterior discoidal part is inipunctate ; it is wider than long,. 



and the outer margins which are slightly rufescent are strongly 



re flexed, especially in the posterior part ; elytra broader than the 



prothorax at the base and with the shoulders not much rounded,. 



parallel for half the length, then slightly ampliated, and only 



moderately attenuated in the posterior part, with the sutural angle 



somewhat blunt, the intervals are plane and the stria? finely 



punctate, the third interval bears in the anterior part a puncture 



situated almost on the third stria, and a post median one impinging 



on the second stria ; the abdomen and median part of the meta- 



sternum are ferruginous and impunctate, the lateral part of the latter 



and the episterna are closely punctate ; the two sexes are alike, and 



the anterior tarsal joints are not sulcate in the male.
