Lake Superior and St. Mary’s River.’ Shining piceous, smooth, more elongate 
than usual. Head flattened, vertex bifoveate, front a little retuse; palpi testa- 
ceous; thorax longer than wide, slightly campanulate, not narrowed behind, 
foveate each side near the base, and slightly transversely impressed at the middle 
of the base. Elytra elongate oval, nearly twice as wide as the thorax in their 
widest part, conveX, sparsely and finely punctured with a fine hair proceeding 
from each puncture; base each side bifoveate. Legs slender, thighs rufo-piceous, 
tibiz and tarsi testaceous. 
2. S. marie, rufo-piceus, parce pubescens, vertice bifoveato, thorace campa- 
nulato ante basin obsolete impresso, lateribus foveato, coleopteris ovalibus obso- 
lete parce punctulatis. Long. :065. 
One specimen, St. Mary’s River, Michigan. This species is very similar to 
the preceding, but the thorax is more rounded on the sides anteriorly, and dis- 
tinctly narrowed behind; the basal impression is hardly visible, the lateral fovez 
are less deep; the elytra are wider and much less distinctly punctured; the base 
is marked as in the preceding with four punctures, causing the humeri and suture 
to appear elevated. 
3. S.cribrarius, rufus, nitidus, flavo-pilosus, thorace basi subtiliter 4- 
punctato, elytris elongato-ovalibus, grosse punctatis. Long. -04. 
Habersham County, Georgia. This species very much resembles the next, but 
the color is paler, the form a little less slender, and the punctures of the elytra 
more numerous and less large; as in it the anterior thighs are much incrassated, 
the others are slender. The thorax is narrowed behind, not sinuate on the sides, 
and the basal punctures are very small. 
4. S. perforatus, nigro-piceus, pilosus, thorace basi 4-punctato et transver- 
sim impresso, coleopteris elongato-ovatis, minus dense variolosis, antennis pedi- 
busque flavis. Long. -04.

anal York and Massachusetts, rare. The thorax is slightly sinuate on the 
sides. 
do. 8.sparsus, rufo-piceus, pilosus, thorace postice angustato, basi 4-punc- 
tato, et transversim subimpresso, coleopteris elongato-ovatis, parce punctatis, basi 
utrinque bifoveatis. Long. -04. 
San Jose, California. Form and size of S. perforatus, but the thorax is not 
sinuate on the sides, and the elytra are foveate at base: the punctures are small 
and much less dense than in S. cribrarius. 
6. S.angustus, valde elongatus, piceus, subtiliter pubescens, thorace elon- 
gato, ovato, elytris minus convexis, sutura ad basin, humerisque elevatis, antennis 
extrorsum magis incrassatis. Long. :03. 
San Jose, California. A small species very remarkable by its narrow form. 
By the shape of its thorax, which is neither cordate nor quadrate, but oval and 
narrowed posteriorly, it seems to unite Schaum’s groups 1 and 2 (Germ. Zeitschr. 
5, 465). The antenne and feet are ferruginous, or rufo-piceous; the former are 
more thickened externally than in the preceding species, and are not longer than 
the head and thorax: the thighs are somewhat dilated.

7. 8. Schaumii, fusiformis, pilosus, rufo-piceus, thorace antrorsum angus- 
tato, basi non impresso, elytris basi subfoveolatis, pedibusque rufis, femoribus

Louisiana, Dr. Schaum. One of the largest of our species, and easily distin- 
guished by its rufous elytra and unimpressed thorax. Body fusiform, wider pos- 
teriorly, rufo-piceous, shining. Head densely covered with erect reddish hair ; 
antenne as long as the head and thorax, rufous, joints 3—6 small, equal, 7th a 
little longer and thicker ; 8—10 about one half longer and thicker than the 7th, 
globose; 11th oval, subacute: penultimate joint of the maxillary palpi regularly 
obconical, the last very small. Thorax longer than wide, densely pilose, narrowed
