posterior tarsi, almost filiform ; the penultimate joint of all bifid, but 
ot bilobate. All the species quoted by Count Dejean are foreign to 
Europe, and belong, generally, to America*. 
2. The second section, that of the Bipartiti, — Scaritides, Dej. — 
which in relation to their habits might also be be styled Fossores, is 
composed of Carabici with elytra* either entire or slightly sinuated 
at their posterior extremity ; having frequently gi’anose and geni- 
culate antennse ; a broad head, large thorax, usually shaped like a cup 
or almost semi-orbicular, and separated from the abdomen by an 
interval which causes the latter to appear pediculated ; the legs gene- 
rally but slightly elongated, their tarsi usually short, and similar in 
the two sexes, or nearly so, without any brush beneath, and sim^jly 
furnished with ordinary hairs or cilia. The two anterior tibiae are 
dentated, and in several palmated or digitated ; the mandibles fre- 
quently strong and dentated. There is a tooth in the emargination 
of the mentum. They all keep on the ground, conceal themselves 
either in holes which they excavate, or under stones, and frequently 
only leave their retreat at night. They are usually of a uniform 
black. The larvae of the Ditomus bucephalus, the only one that has 
been observed, has the form and mode of life of the larvae of the 
Cicindelae. They are more particularly proper to hot countries. 
The three first subgenera, on account of their labial palpi, which 
are terminated by a larger, securiform or triangular joint, form a 
particular group; the last of these subgenera leads us to Scarites, 
Avhilst the first, which, as respects the absence of the emargination in 
the internal side of the two anterior tibiae, constitutes an exception, 
seems to connect itself with the first subgenera of the family. They 
all have stout and dentated mandibles. The external maxillary palpi 
terminate in a rather larger joint ; the thorax has the form of a cup 
or truncated heart ; the abdomen is pediculated. 
Two of the subgenera of this group form a special subdivision. 
Their anterior tibiae are not palmated. Their antennae consist of 
cylindrical joints, or such as resemble reversed cones. The mentum 
covers the whole under part of the head as far as the labrnm, and fre- 
qucmtly exhibits no transverse suture at its base. The body is much 
flattened, and is apterous in several. They all belong to the eastern 
continent or to New Holland. 
Enceladus, Bon. 
The inner side of the anterior legs unemarginate ; first joint of the 
antennae but little elongated, and almost cylindrical, the third shorter 
than the second ; middle of the superior margin of the ligula pro- 
jecting in the manner of an angle or tooth ; thorax almost in the 
form of a broadly truncated heart, the posterior angles slightly dilated 
and pointed ; labrum emarginate or nearly bilobate.
