Type of the Genus , Staphylinus murirms Linn. 
Staphylinus Linn., Fab., Gyll., Erich., Curt. — Trichoderma Step. 
Antenna inserted before the eyes, near the base of the labrum, 
as long as the thorax, slightly clavate and geniculate, pube- 
scent, 11-jointed; basal joint long, 2nd and 3rd short, pyriform, 
the latter sometimes a little longer, the remainder moniliform, 
slightly increasing in diameter, terminal joint with a tubercle 
or hook at the lower extremity (6). 
Labrum exserted, transverse, deeply notched, forming 2 rounded 
lobes ciliated with long hairs and a few bristles (1). 
Mandibles porrected, long and slender, curved, the apex form- 
ing a long claw with 2 or 3 teeth on the inside, deeply emar- 
ginate below the middle, with a densely pilose lobe towards the 
base (2). 
Maxilla terminated by a densely hairy ovate lobe, apparently 
articulated, and a larger and long one on the inside densely ci- 
liated. Palpi longish, filiform, slightly bristly, 4-jointed, basal 
joint short, pyriform- truncate, 2nd the longest, 3rd scarcely so 
long, both clavate, 4th the same length, subfusiform (3). 
Mentum very short, transverse, sides rounded, anterior margin 
concave. Labium elongated, narrowed at the middle, apex cor- 
diform, the sides forming 2 lobes. Palpi attached to the disc 
towards the apex, triarticulate, first 2 joints equal, oblong, the 
latter bristly on the inside towards the extremity, 3rd a little 
longer, slenderer and fusiform (4). 
Head a little broader than the thorax, suborbicular : eyes not large, 
lateral and oval. Thorax ob ovate -truncate, anterior angles acute :

The Staphylini, called Rove-beetles in England, form a ge- 
nus of Linne’s, containing an immense quantity of species, 
which now comprise many subfamilies and numerous genera. 
The present group is distinguished from Ocypus by the shape 
of the mandibles, and the intermediate coxae are more remote. 
Erichson has united Emus and Creophilus with our Staphy- 
lini, although the trophi and antennae vary considerably. The 
Staphylini are principally found under the dried dung of horses
