Placodes opacus, sp. n. 



Oblongus, coiwexiusculus, opacus, niger, rugoso-puiictissimus ; 

 fronte stria biarcuata ; pronoto stria marginali obsoleta, laterali 

 in angulo desinente, interstitio 4-puTictato ; elytris striis indis- 

 tinctis ; propygidio pygidioque grosse et dense punctatis ; pro- 

 sterno baud striate ; mesosterno profunde inciso, antice immar- 

 giuato. 



L. 151 mill. 



Oblong, somewhat convex^ opaque, black ; the head, frontal 

 stria com])lete and biarcuate, but somewhat obscured by the 

 rough sculpture behind the stria, on either side is a coarse 

 dense punctuation, which does not, however, close in at the 

 base; the thorax is wholly punctured, punctures coarse at the 

 side, marginal stria scarcely noticeable, lateral stria ceases 

 behind the eye and is not conspicuously deep, the interstice 

 has four rather small punctures set at equal distances along 

 it; the elytra densely rugose and the stria? obscurely marked, 

 two humeral and six dorsal, all apparently complete^ but only 

 just traceable along the punctate surface, 3, 4, 5, and sutural 

 punctiform ; the propygidium and pygidium are very coarsely 

 and densely punctate; the prosternum, keel without striaj, 

 rather densely punctate at the base and between the coxge, 

 anterior lobe somewhat similarly punctured, intervening area 

 with sparser punctures, on either edge of the keel before the 

 cox£e is a small but distinct fovea; tlie mesosternum is deeply 

 incised anteriorly and faintly marginate at the sides only; the 

 anterior tibise have two broad teeth, intermediate widely 

 emarginateon the outer edge at the tarsal end and terminating 

 in a rather acute tooth.
