The sides strongly sinuate behind, becoming parallel for a considerable dis- 

 tance before the base, the angles right; elytra very convex, the striae dis- 

 tinct, abruptly much confused in about lateral third, the punctures coarse. 



10 graTidiis 

 The sides oblique behind and feebly sinuate ; elytra with series of moderate 



punctures, but not distinctly striate 11 su1>tilis 



9 — Elytra 18-striate, the strise sometimes much confused near the sides ; con- 

 cave elytral margin never violaceous 10 



Elytra 16-striate ; intervals frequently interrupted ; reflexed margin nearly 



always distinctly violaceo-metallic in lustre 13 



Elytra 14-striate ; reflexed margin of the elytra with metallic reflection, ex- 

 cept in cordatus 14 



10 — Elytral strise feeble, rather feebly and indistinctly punctate, the second, 

 third, sixth and seventh irregular ; elytra quite depressed, evenly ellipti- 

 cal and subopaque 12 symmetricus 



Elytral strise even except near the sides, the intervals even and not inter- 

 rupted, at least internally 11 



Elytral strise more uneven, the intervals more or less interrupted throughout 

 the width, much broken up in a broad lateral area ; elytral margins more 



narrowly reflexed, the general sculpture A'ery deep and rugose 13 . 



11 — Prothorax narrow, longer than wide, the reflexed side margin very nar- 

 row ; elytra deeply and evenly striato-punctate 13 striatus 



Prothorax wider than long except in mimus and catenulatus. 



Sides of the prothorax deeply sinuate posteriorly and parallel before the 

 base, the angles right. 

 Elytra oblong-oval, strongly convex, the sculpture greatly confused in a 

 broad area toward the sides ; large species. 

 Strise unevenly spaced, the wider intervals each with an uneven sup- 

 plementary series of punctures ; margins of the prothorax more 



strongly reflexed 14 fiicbsianus 



Strise evenly spaced ; intervals more convex, generally, or in the fe- 

 male at least, with feebly marked supplementary series of punc- 

 tures which are more obvious on the alternate intervals ( alternatus 



Mots?) 15 ventricosiis 



Elytra elongate-oval, narrower and much less full at the humeri, the 

 strise even, deep and distinctly punctured almost to the side margins, 

 the intervals even, rather convex and smooth throughout ; surface with 



a faint blue-black lustre 16 gentilis 



Sides of the pr othorax constricted before the base, thence diverging to the 

 basal margin ; elytra nearly as in gentilis, the prothorax larger, wider 

 than long, with the side margins much more broadly reflexed ; surface 



deep black without trace of bluish lustre 17 strictus 



Sides of the prothorax finely margined, only moderately sinuate toward 



base, the disk narrower, as wide as long ; basal angles rectangular as 



usual ; elytral punctures very coarse and deep, evenly arranged along 



rather fine strise. 



Elycral strise not impressed ; disk of the pronotum flat 18 niin(iu§
