 L. ^ mill. 



Oval, convex, ajneous above and sliining, black beneath ; 

 the head is closely not coarsely j)unctured and without frontal 

 stria? ; the thorax, marginal stria entire, punctured on the 

 lateral borders, with a small impression behind the eye, much 

 narrowed anteriorly and not ciliate at the sides. The elytra, 

 tiie humeral area is red, the dorsal striaj, except the sutural, 

 are very short, or wanting (as the fifth), tlie sutural is shortened 

 before the apex, otherwise it is similar to the sutural stria 

 figured by ]\[aiseul for S. hisignatus, Er. (Mon. 1855, fig. 13); 

 on either side of the sutural stria, just behind the middle, is 

 a small fovea, the elytral apices are moderately, not densely 

 punctured, the epipleural stria is continued round the apex of 

 each elytron, but it does not quite reach the suture. Tlie pro- 

 sternum, the striaj on the keel are strong and anteriorly diverge 

 (similarly to those of S. hisignahis) ; tlie mesosternum is 

 faintly and sparingly punctulate, the marginal stria is complete 

 and w idely sinuous, but it is not quite close on the anterior 

 edge ; the anterior tibiaj are 7-8-dentate. 



This species is easily distinguished from its congeners, 

 *S'. bisignatuSj Er., -S^. hpidus, Er., and others, by its red 

 shoulder and complete mesosternal stria.

L. 2 mill. 



Cylindrical, black and shining, legs and antennje reddish, 

 surface above rather densely and strongly punctured, many of 

 the punctures appear under the microscope minutely ocellate; 

 the head is rather convex ; the thorax, lateral stria well-marked, 

 but it is not continued behind the neck, on the edge before 

 the scutellum there is a cluster of dense punctures ; the elytra, 

 the smooth humeral space is very distinct ; the prostemum, 

 there is a transverse marginal stria along the apical margin 

 of the anterior lobe, but down the sides there are only a iQyf 

 marginal punctures, the keel and lobe have a very iaw but 

 conspicuous and irregular |)nnctures, the stritn on the keel 

 are very conspicuous and posteriorly do not quite reach the
