Length usually a quarter of an inch or less, elytra often reddish Xantholinus. 
Greopliilus, Stephens, contains two N. A. species, one of which, the 
C. villosus, Grav., is not uncommon. It is a robust species, about seven- 
tenths of an inch long, black, with a broad ash-colored band across the 
elytra, and another across the abdomen, composed of short hairs. The 
specific name villosus — hairy , is expressive of this character. The gen- 
eric name means a lover of flesh. Leistotrophus, Perty, a name expres- 
sive of the ferocious character of the species, contains hut one if. A. 
species, L. cingulatus, Grav. It is of about the same size as the prece- 
ding, of a gravish-brown color, indistinctly spotted with black. The 
end of the abdomen has a golden luster. Twenty-one species of Staph y- 
linus proper are enumerated in Dr. LeConte’s catalogue of 18G3. Oue 
of the largest and most common species is the S. maculosus, Grav., eight 
or nine-tenths of an inch long, of a dark cinnamon-brown color, with a 
black scutellum, and a row of obscure square blackish spots along the 
middle of the abdomen. A somewhat similar but rarer and more ele- 
gant species is the S. vulpinus or fox-colored Staphy linns of Nerd man. 
In this the colors are brighter, and the abdomen is black, tipped with 
fulvous, with golden incissions, and two cinereous pubesceut spots at 
the base of each segment. The S. cinnamopterus , Grav., is also cinna- 
mon-colored, with the abdomen nearly black ; but it is a smaller species, 
being but half an inch, or a little more, in length. S ■ tomentosus, Grav., 
is six-teutlis of an inch long, and of a deep, dull black color. S. viola- 
ceous is of about the same size, also black, but with the thorax and 
elytra of a rich violet hue. The abdomen is varied, along the margin 
with a silken ash-colored pubescence. 
Ocypus , Kirby, meaning swift-footed, contains but one species, the 
0. ater, Erichs., seven-tenths of an inch long. Philonthus, Curtis, mean- 
ing a lover of dung, contains many species, a few of which exceed half 
an inch in length ; but most of them range from two to three-tenths of 
an inch. A considerable number of our species are arranged under the 
genus Quedius, of Stephens, which is closely allied to Philonthus, but 
differs in having the thorax with a sharp simple margin, and a fe
