nearly twice the length (being as eight and a half to four and a- 

 half), and the greatest width is very near the base. The basal 

 lobe of the thorax is rather narrow, very short, and slightly 

 raised up and emarginate in the middle. The elytra are just a 

 hair's breadth narrower at their widest part than the thorax. 

 There are about seven rows of very fiue and faint punctures on 

 each elytron, and the sub-apical larger puncture on each is of 

 only moderate size. The thickened humeral portion of the 

 elytral margin is erect, and very abrupt. There are about 

 seven punctures placed confusedly on the anterior margin of 

 each elytron, and each lateral marginal row contains about 

 twenty-two punctures, which, however, become faint and diffi- 

 cult to count near the apex. The exterior ridge of the anterior 

 tibise has four teeth above the apical two large ones, of which 

 the lowest is distinctly, and the next scarcely visible when the 

 tibia is viewed from a point perpendicular to the upper surface 

 of the tibia, while the topmost is hardly discoverable except by 

 its seta ; the inferior ridge has nine teeth, commencing some 

 distance back from the apex of the tibia. 



I have a single specimen in my collection. It was taken at 

 Powler's Bay. 



C. Made ai/i, s]).noy. Nitidum ; laeve ; nigrum; pedibus picei& 



antennis palpisque ferrugineis, prothorace virid - mar- 



ginato, elytris violaceo et viridi micantibus, splendide 



viridi marginatis ; capite fortiter transverse, sulcis lougi- 



tudinalibus profunde impressis haud curvatis postice an- 



ticeque divergentibus, antennis gracilibus sat elongatis ; 



prothorace dimidio latiore qiiam longiore, sat anguste mar- 



ginato, canaliculate, basi biimpresso antice subtruncato^ 



postice late sublobato, angulis posticis obtusis subreflexis ; 



elytris ovatis antice paulo angustatis, sat late marginatis, 



antice medio subexcavatis, secundum suturam depressis 



obsolete seriatim foveolatis (? exemplo deformato), antice 



et disco IsBvibus, marginibus lateralibus seriatim punctu- 



latis, humeris reflexis parum prominulis ; *tibiis anticis- 



tridentatis ; subtus nigrum, elytrorum epipleuris splendide 



micantibus. Long., 17 mm. ; lat., 6 mm. 



This is an extremely distinct species. In different lights the 



elytra display all shades of blue, violet, and green. The absence 



of large discal elytral punctures in conjunction with the visibility 



of three external spines on the front tibi?e seems to distinguish it 



from all other species of the genus. It seems to occupy an in- 



*0n the right tibia of the specimen described one of the teeth in the in 

 ferior ridge is biiid, so that there appear to be ten teeth, but the accidental 

 character of this formation is evrdent, as the additional pseudo-tooth bears 

 no seta.
