This I take to be the S. rugotmlm of Sotier. With regard to S. rupoxulu* 

 and some allied species, it appears to me there if lome confusion. M. GroeVin, 



who first described the former, says thai the thorai ii Eta form beii 



well-marked hexagon, with the sides angulated and margined; thai thru. 

 on the elytra are rugose, and that the underside and legs are rugose, the latter 

 tolerably stout. Now M. Sober says of bis S. rugosuku, thai the thorai 



more entire on the lateral margins, and a little leal margined than in bil s 

 Gayi; that the back is covered with deep punctures, squeezed and separated 

 by irregular shining intervals, larger at the centre than upon the lides, and 

 not at all granulated; the ribs on the elytra of the interstices narrower and a 

 little less elevated than in ,V. Qayi\ the posterior tubercles imaUer and a little 

 more pointed ; the legs evidently less robust, with the thighs strongly ssssefarssi 

 It appears therefore that M. Gueriifs S. rugoeubu has the thorax. ribs of * I' 

 and legs rugose, viz. granulated, and that the thorax and legl <>f M. Sober" s 

 S. rugosuhts are punctured.

Length 6^ lines, breadth 3^. 



Dead-black; antenna? very short, 2 basal and apical joints and palpi ferruginous: rlvj 

 and head thickly and coarsely punctured, the former slightly concave in front, with a 

 transverse suture, the extremities of which are hooked : thorax more than twice as 

 broad as the head, transverse-orbicular, concave before, the angles rounded ; straight 

 behind, the angles forming a minute well-defined tooth ; the sides perfectly convex and 

 delicately reflexed, the entire surface thickly and strongly punctured with irregularly 

 crowded punctures; an obscure impression down the middle, and an indistinct t 

 on each side ; scutel short and broad : elytra much broader than the thorax, very • •■ 

 the apex attenuated and slightly margined, the back is transversely wrinkled, and there 

 are 6 lines of punctures on each elytron ; there are also 7 narrow slightly-eln
