Staphylinus, Fab. 
Or the true Staphylini, all the palpi are filiform, and the antennae 
are inserted between the eyes, above the labrum and mandibles. 
Some, particularly the males, have the anterior tarsi greatly dilated, 
and the antennae separated at base ; the length of the first joint of the 
latter is equal, at most, to that of a fourth of the whole number. 
The head is but slightly elongated. In some systems, those species 
alone which present the above characters, constitute the genus Staphy- 
linus. The /S. dilatatus, Fab., Germ., Faun. Insect. Europ., VI, 14, 
has even been separated from it, to compose another, on account of 
its antennae, which form an elongated serrated club. According to 
the observations of M. Chevrolat, a zealous entomologist, this Insect 
feeds on caterpillars which it searches for on trees. 
S. hirtus, L. ; Panz., Faun. Insect. Germ., IV, 19. Ten lines 
in length; black; very hairy; superior surface of the head, 
thorax, and last abdominal annuli covered with thick hairs of a 
glossy golden-yellow ; elytra cinereous-grey, Avith a black base ; 
under part of the body bluish-black. Nortli of Europe, France, 
and Germany. 
aS. olens. Fab., Panz. ib., XXVII, 1. An inch long; dead 
black ; head wider than the body ; wings reddish. Its ova are 
remarkably large. Very common in the environs of Paris, 
under stones. 
S. maxillosus, L. ; Panz. ib. 2. About eight lines in length; 
black ; glossy ; head wider than the thorax ; great part of the 
abdomen and elytra cinereous grey, dotted and spotted with 
black. Inearth, dung, &c. 
, S. miirmus,Fa.h. •, Panz., ib., LXVI, 16. From four to six 
lines long ; head, thorax and elytra deep bronze, glossy, Avith 
dusky spots ; scutel yelloAvish, marked Avith tAA'o atrous spots ; 
abdomen black ; greater part of the antennse reddish. Found 
Avith the preceding, 
S. erythropterus, L. ; Panz., XXVIII, 4. From six to ten 
lines in length ; black ; elytra, base of the antennae, and legs 
fulvous 
The others, Avhich are linear, Avith a head and thorax elongated in 
the form of a long square, have their antennae approximated at base, 
and strongly geniculate and granose ; their anterior tarsi are usually 
not at all or but very slightly dilated. The anterior tibiae arc spin- 
ous, Avith a stout spine at the extremity. The labrum is small. 
They form the genus Xantholinus of some entomologists f.
