minate by a fusiform joint ending in a point. The body is elongated 
and cylindrical, and the mandibles are long, narrow, and without any 
remarkable teeth, like those of the Oxygnathi. 
OxYSTOMUS, Lat. 
The labial palpi almost as long as the exterior ones of the maxillae, 
recurved, the first joint salient and cylindrical, the second but slightly 
elongated, and the last fusiform, long and acutely pointed at the end ; 
the antennae completely moniliform from the middle of their length, 
with the first joint as long as the three following ones united 
Camptodontus, Dej. 
The labial palpi evidently shorter than the external ones of the 
maxillae, not recurved, and terminated as well as the latter by a fusi- 
form joint ; a greater part of the joints of the antennae resembling in- 
verted cones ; the length of the first hardly surpassing that of the two 
following ones taken together f. 
I'he others, w'hose anterior tibiae are not dentated externally, but 
simply didactyle at the end, have short mandibles, projecting but lit- 
tle beyond the labrum ; the labrum coriaceous and entire ; the ligula 
advancing beyond the emargination of the mentum, glabrous, or but 
slightly pilose, with separate,' salient, and membranous paraglossae ; 
the exterior paljji are terminated by an oval joint, acuminated at the 
extremity. 
They are small, frequent humid places, and are not strangers in 
northern countries. 
Clivina, Lat. 
Three stout teeth on the external side of the two anterior tibiae, and 
one on that of the next two+. 
Dyschirius, Bon. — Clivina, Dej. 
Nothing but dentations or very indistinct and small spines on the 
external side of the two anterior tibiae, and where the extremity of 
this side is usually extended into a long point in the form of a spine, 
and opposed to another consisting of a stout spur on the internal side. 
The last joint of the labial palpi is thicker in proportion than that of 
the Clivinae, and almost clavato-securiform. The thorax is usually 
globular §. 
Our second and last subdivision of the Bipartlti will comprise those 
whose anterior tibiae are neither dentated externally, nor bidigitated 
at the extremity, and where the second joint of the antennae is evi- 
dently shorter than the third. They closely approximate to the two 
last subgenera in the organs of manducation, and have been confounded
