Louisiana, Schaum and Wapler. This:species is very similar to the preceding, 
but is narrower, being of the form of S. basalis, with which it agrees also in the 
antennz, but differs in size, and in having no impression at the base of the thorax. 
The feet are testaceous, the thighs are darker: the tip of the abdomen beneath is 
yellowish.

New York and Pennsylvania, in the nests of a small black ant. This species 
is more obtusely rounded behind than the preceding species of this division. The 
pubescence is more prostrate, and very dense. The antenne are not longer than 
the head and thorax: the four last joints forma club larger in proportion than in 
the other species, and as long as the other joints collectively. The thorax is 
less narrowed in front than in the preceding species, and isa little rounded on 
the sides: there is no impression at the base: the elytra are slightly foveate 
inside of the humerus.

Pennsylvania, Haldeman; found with a small fuscous ant. This species is of 
a bright testaceous color, and entirely glabrous. The head is convex and rounded. 
The antenne are longer than the head and thorax, the joints 3—7 are cylindrical, 
the four last are globular and about twice as thick as those which precede them. 
The thorax is a little wider than the head, longer than wide, slightly narrowed 
in front, very slightly rounded on the sides, flattened on the disc, and deeply 
foveate near the basal angles: the fovew are connected by a transverse impres- 
sion. The elytra are twice as wide as the thorax, regularly oval and convex, 
forming a slight angle with the thorax; the base is broadly foveate inside of the 
humerus. The anterior thighs are strongly clavate. 
16. S.obscurellus, piceus breviter pubescens, thorace longiusculo, antice 
subangustato, elytris basi vix impressis, antennis articulis rotundatis, pedibusque 
rufescentibus. Long. :045. 
One specimen, Liberty County, Georgia. A small species, easily distinguished 
by its piceous color and elongate thorax. Head convex, smooth, strongly pilose 
at the posterior angles: antenne a little longer than the head and thorax, the 
joints after the 2d globular, the four last about one-third thicker than those which 
precede, the last being larger and obtuse. Thorax pilose, not wider than the 
head, nearly one-half Jonger than wide, very slightly narrowed in front, apex trun- 
cate, sides straight. Elytra one-half wider than the thorax, and forming an almost 
indistinct angle with it, obliquely narrowed behind the middle, slightly pubescent ; 
base scarcely foveate. Feet rufous, thighs clavate. 
17. S.clavatus, rufo-piceus, tenuiter pubescens, thorace longiusculo, antice 
angustato, basi tenuiter impresso, elytris dorso depressis, basi unifoveatis, an- 
tennis fortius clavatis articulis subtransversis. Long, -045. 
One specimen, Liberty County, Georgia. Elongate rufo-piceus; head convex, 
very strongly pilose, each side posteriorly so as to appear truncate at base: an- 
tenne as long as the head and thorax, joints 3—6 rounded, short, closely united: 
*Schaum erroneously cites the Journal of the Academy of Natural Sciences 
for the descriptions of this species, and 5. clavipes.
