terminated by an ovoido-cylindrical joint ; the same joint of those of 
the labium elongated and fusiform. I have not perceived a tooth in 
the emargination of the mentum * * * § . 
3. Our third section of the Carabici, that of the Quaurimani, — 
Harpalicus, Dej. f, includes those, otherwise similar to the last in 
the pointed termination of the posterior extremity of their elytra, in 
the males of which the four anterior tarsi are dilated ; the three or 
four first joints are in the form of a reversed heart or triangular, and 
nearly all terminated by acute angles ; they are usually furnished 
underneath (the Ophoni excepted) with two ranges of papillae or 
scales, with an intermediate linear space. 
The body is always winged, and generally oval and arcuated or 
convex above ; the thorax is wider than it is long, or at most nearly 
isometrical, square or trapezoidal. The head is never suddenly con- 
tracted posteriorily, and the antennae are equal throughout, or slightly 
and insensibly thickened near the extremity. The mandibles are 
never very strong. The exterior paljji are terminated by an oval or 
fusiform joint, longer than the preceding one. The tooth of the 
emargination of the mentum is always entire, and in some is want- 
ing :{:. The legs are robust, the tibiae spiny, and the hooks of the 
tarsi simple. The intermediate tarsi, even in the females, are short, 
and, with the exception of the dilatation, nearly formed like the an- 
terior, These Carabici prefer sandy and hot localities. 
This section is composed of the genus Harpalus, as limited by Bo- 
nelli in his tabular view of the general distribution ef the Carabici. 
Nev/ sections have still more diminished its extent. They are all 
subordinate to the three following divisions. 
The characters of the first are : the emargination of the mentum 
unidentate§; labrum emarginate ; head and anterior extremity of 
the thorax as wide as the abdomen or wider ||. It comprises three 
subgenera. 
Acinopus,, Zieej. Dej. 
Filiform antennse, composed of short but cylindrical joints ; tho- 
rax insensibly narrowed from before backwards, with the posterior 
angels very obtuse or rounded ; mandibles destitute of teeth ; tooth of 
the emargination of the mentum widely truncated

-f- This appellation harmonizes with those of the two following sections, and is 
founded on an exclusive eharacter : it therefore seems to me to be preferable to that 
of Ha)-palici, employed by Bonelli. 
X The ligula, as in the two following sections, is always remarkably salient, obtuse 
or truncated at the end, and accompanied by two distinct, membranous paraglossae 
in the form of auricles. 
§ If the Cyclosomi have the four anterior tarsi dilated, they Avill form a fourth 
division on account of the two teeth in the emargination of the mentum. 
11 The head large ; paragloss^e rather broad in comparison with the true ligula, 
and rounded at the end ; second joint of the .antenna; somewhat shorter than the 
third ; intermediate tarsi of the males rather less dilated than the anterior.
