sparsely punctate. Thorax nearly square, sides in front slightly arcuate, 
hind angles rectangular, disc depressed or very feebly convex, a slight im- 
pression on each side of middle at base, surface rather coarsely but not 
densely punctured. Elytra scarcely wider at base than the thorax, sides 
feebly arcuate, disc depressed, surface striate, strize punctured. Body be- 
neath rather sparsely punctate. Length .08-.12 inch ; 2-8 mm. 
This species occurs over our entire country from the At- 
lantie to the Pacific, and from Hudson’s Bay to Texas. 
PHILOTHERMUS Aubé. 
Antenne eleven-jointed, last two joints forming an abrupt club, the ter- 
minal joint longer than the tenth, second and third joints moderately long 
equal, inserted as in Cerylon, antennal grooves absent. Head and palpi as 
in Cerylon. Anterior coxe moderately separated, the prosternum oval at 
tip, coxal cavities open behind. Tibi slightly broader from the base, nar- 
rowed at tip, the apical angle not prolonged, and without terminal spurs. 
Middle coxze more distant than the anterior. Posterior coxee widely distant. 
Trochanters distinct on all the femora. First abdominal segment as long 
as the next three together, segments two to five nearly equal. Scutellum 
transverse. Tarsi with the first three joints very short, very little longer 
together than half the fourth. 
The points of difference between this genus and Cerylon, 
with which it has been associated, are many. The most 
important is the open anterior coxe, following which in 
value is the structure of the antenne, and lastly the form of 
the tibize: which resemble Cicones, and have no spurs. 
Two species are known in our fauna. 
Body beneath rather sparsely punctured, above glabrous ; punctures not 
attaining the tips of the elytra which are nearly smooth. glabriculus. 
Body beneath coarsely and deeply punctured, above pubescent ; punctures

P. slabriculus Lec. New Species, 1863, p. 69. 
Elongate-oval, castaneous, shining, glabrous. Head sparsely punctate. 
Thorax broader than long, broader at base, apex emarginate, base feebly 
bisinuate, sides regularly arcuate from apex to base, margin moderately 
reflexed, disc sparsely and regularly punctate. Elytra not wider than the 
elytra, and with rows of rather coarse punctures not closely placed, evan- 
escent at the tip, striae not impressed. Body beneath sparingly punctate, 
especially along the middle. Length .08-.12 inch ; 2-3 mm. 
This species occurs especially in the Atlantic States proper. 
not extending westward.
