riate XXXVII., fig. 4. 



Coppery, dull, or not vei'v shining on the upper side, under side 

 bronze, legs greenish bronze ; head very closely punctured ; the 

 punctures are closely set and elongate along the edge of the clypeus ; 

 median part of the head with a very small, slightly elongate tubercle, 

 teeth of clypeus long and sharp ; prothorax convex, very distinctly 

 serrate laterally, grooved transversely along the base for about half 

 the length, covered with very closely set, small punctures the 

 intei'vals of which are finely granulose on the sides; in the middle 

 there is a longitudinal median smooth line, very narrow in the 

 anterior part, and slightly lanceolate from the median part to the 

 base ; elytra with two supra-marginal carinae, sub-parallel, convex 

 principally towards the median part, sutuYe shining, striae well 

 defined, intervals, shagreened and having two series of closely set, 

 moderately deep punctures ; pygidium covered with closely set, 

 round punctures ; legs fringed with short, blackish hairs ; anterior 

 tibiae foveolato-punctate on the upper side, armed with three sharp 

 teeth outwardly, and having a very rudimentary one at base, sub- 

 laminate inw^ardly from apex to half the length, and with the upper 

 ridge ending in an apical spine at the junction with the edge 

 of the inner lamina, the inner and outer edges are not serrate ; 

 metasternum acuminate at tip and having a deep, ovate impression 

 between the intermediate coxae, and a very slight one near the base 

 connected with the anterior one by a very fine, short impressed line. 



Length 28-30 mm.,; width 17-19 mm. 



Intermediate in form between S. inaslinnus and S. ciiprcns,. 

 Casteln. 



It is not quite so convex as the former, and the prothorax instead 

 of being granulose is very closely punctured ; the two supra-mar- 

 ginal carinae overhang the margin as in .S'. cupreus, and the shape of 

 the genital armature of the 3 is very different from that of l)oth the 

 above-mentioned species.
