S. sutvralisW Ziegler, Proc. Ac. Nat. Sc. 2, 44. 



Pennsylvania, Georgia and Missouri Territory. This insect is most probably 

 S. orbiculatus Guir. (Ci/p/wu orhlctdatus Fabr. Syst. El. 1, 503), but as the 

 description of that species gives the feet as ferruginous, a new examination of 

 the typical specimens is required before the synonymy can be established. 



S. suturalis Guir. (p. 3,) is unknown to me; it corresponds with S. 

 lateralis, except the thorax is entirely black. 



S. californicus Motsch. (Bull. Mosc. 1S44, part 1, p. 35) is unknown to 

 me. His classical description reads as follows : 



" Subovatus, corivexus, nigro-castaneus sjlaber, ore, antennis, pedibusque 

 anteriores testaceis, pedibus posteriores nigro-fuscis ; femoribus incrassatis."

The body in this genus is regularly elliptical, and moderately convex; the 

 thorax is semicircular, produced over the head, and strongly reflexed at the 



margin.
