 Long. 2i lin. 



S. fUifoiTn, rather broader and more convex than the preceding spe- 

 cies; clj'tra less narrowed behind, sliining black above. Head 

 smootli ; fi-i)nt convex ; face concave, divided by a longitudinal 

 ridge whieh run.s upwards to the front, into two large foveas for the 

 insertion of the antenna; ; the latter scarcely longer than the head 

 and thorax, stouter than in any of the rest, their apex scarcely 

 tluckened. Thorax quackate ; sides straight and parallel, obso- 

 letely sinuate, rounded at their apex, anterior angles not pro- 

 duced, obtuse ; above subcyUndiical, impressed on either side near 

 the anterior angles ; sides narrowly margined ; siu-face remotely 

 but deeply jjunctiu'cd. Scutellum smooth. Elytra rather broader 

 than the thorax, foiu- times its length ; sides parallel, shghtly 

 sinuate, less distinctly narrowed towards their apex ; the latter 

 regiilarly rounded ; above convex, depressed at the base between 

 the shoulders, slightly thickened at the apex; sides narrowly 

 margined ; sm-face smooth and shining, finely punctate-striate. 

 Abdomen and legs pitchy black ; pygidium pitchy,

Distinguished from S. metallica, to which insect it is the most 

 nearly allied, by the short tliird joint of its antennae, the quadrate 

 and less thickly punctured thorax, and by its more convex elytra, 

 which are less attenuated towards their apex, and less acutely 

 rounded.
