S. suturalis|| Ziegler, Proc. Ac. Nat. Se. 2, 44. 
Pennsylvania, Georgia and Missouri Territory. This insect is most probably 
S.orbiculatus Guér. (Cyphon orbiculatus 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 Gwér. (p. 3,) is unknown to me; it corresponds with S. 
lateralis, except the thorax is entirely black. 
S. californicus Motsch. (Bull. Mose. 1844, part 1, p. 35) is unknown to 
me. His classical description reads as follows : 
‘“Subovatus, convexus, nigro-castaneus glaber, 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.

‘extending in front of the middle of the elytra; varieties ocenr in which they are 
so much extended as to become confluent on each elytron with the basal spot.
