Discussion: On the basis of the general body shape, transverse 
bands of scales on the elytra, and shape of the male genitalia, S. 
congestus bears the closest resemblance to S. sculpticollis, S. tychoides, 
and S. atratus, but may be distinguished from any of those species by 
its reddish brown body color or by careful comparison of the genitalia. 
Distripution: Most of the records from the material examined 
indicate that this species may be found on the Atlantic coastal plain, 
in the Appalachian highlands, and in the central lowlands region. A 
single record (La Veta, Colo., Casey collection) from the southern 
Rocky Mountains section exists, but the significance of that record 
seems uncertain at this time. The specimens examined are as follows:
