toothcJ on t]w outside nor biilijitute at tlie tips, anil tne second joint of tlie antennfc is evidently shorter than the 

 follcnvinif. Tlicy nearly ai)|)roach, in the organs of the moutli, the two last suhgenera; and have been confounded, 

 by some nriters, with Scarites, of whicli they have the appeai'ance. 



Morio, Latr. (with the autennaj of equal Icng-th throngliout, thighs oval, and tibia: triangular, Harpiilus moniU- 

 cornis, Latr. &c.), and Oza-na, Oliv. (with the antenna; thickened at the tips, and the femora and tibia narrow and 

 elongated, Oza-na denlipes, Oliv. &c.), have the body narrow, elongated, nearly parallelopiped, the thorax nearly 

 square, and the last joint of the external palpi nearly cylindric. All the species are exotic. 



Those which have the body oval or oblong, with the thorax nearly cup or heart-shaped, or orbicular, the last 

 joint of the outer palpi nearly oval or fusiform, and the labrum notched, compose the remaining genera. 



Dilouius, Bonelli, have the palpi shorter than the head, the thorax cup or heart-shaped, and the tai-si sliort. 

 Some species, to which Zeigler restricts the generic name, liave the body more elongated, the head separated at 

 the sides from the thorax by an angular space, and often armed in the males with horns ; whilst the others, which 

 form the genus Arhtus, Zeigl., have the body shorter, broader in front, anil the head and thorax neai'ly continuous. 



Apotomus, Hofl'm., have the anterior palpi very long, the thora.x orbicular, andtlie tar.si tiliforni and elongated.

[The typical insects of this section, from llie observations of H. Lefehvrc de Cerisy, appear to be 

 nocturnal in their haljits ; and itence their colours are, for the most part, black or obscure. The larger 

 species are eliietly inhabitants of the Old World. They burrow in the earth, oi sand of the sca-slun-c, 

 for which their palmatcd fore-legs well lit tliem. They are insects of prey, lurking Ijy day in holes 

 and under stones, and feeding at night upon Melolonlhida:, or other soft-bodied insects. No generic 

 additions of importance have been made to this group.] 



3. Our third section of the Carabici — that of the QoArRiMANi, or IIarpaliens of Dcjcan — comprises 

 those which, in other respects similar to the last in the elytra terminated posteriorly in a point, have 

 the four anterior tarsi dilated in the males, the three or four basal joints being in the shape of a heart 

 reversed, or triangular, and nearly all of them terminated by acute angles. Their under-side is generally 

 (except in Ophoims) furnished witli two rows of papillae or scales, with a broad space between. The 

 l)f)dy is always winged, generally ova], and arciied or convex above, with the thorax broader than long, 

 or at most nearly isometrical; the head is never sutidenly narrowed hehind; the antenntc are of equal 

 thickness throughout, or but very shglul}" thickened towards the tips ; the mandibles are not \ery 

 strong; tlie tooth in the notch of the mentuin is alwa\s eutire, hut it is wanting in some species ; the 

 tonguelet is truncated at the ti[), and accompanied by two ear-like membranous paraglossre ; tlie legs 

 arc robust, and the ungues of tlie tarsi simple ; the intermeihate tarsi, as in the females, are short, and, 

 with the exception of the dilatation, are similarly formed to the anterior iiair. 



These Carabici frequent sandy situations exposed to tlie sun. This section is composed of tlie genus 

 llarpaltis, as restricted by Jjonelli. New groups liave since still further diminished its extent. They 

 consist of the three following divisions ; — 



The first uf these divisions has for its characters, — notch of the mcntum witli a single tooth, labrum 

 notched, and the head and fore part of the thorax as broad as, or broader than, the abdomen. 



Acinopui; Zeigl., with filiform antennae, the joints short but cylindrical, the thorax narrowed gradually from 



the front to the back, and the hinder angles very obtuse. Type, llaipahts tiuyaccp/ialm; Latr. [South of Europe.] 



Dajtlus, Fischer, with the antennee moniliform after the fifth joint, and the thorax narrowed suddenly towards 



the posterior angles, which are pointed. Type, D. pict/is, Fischer ; Russia. Pangus, JMegerle {P. pemi/lranicus}^ 



does not appear to me to differ essentially from Daptus. 



The second of these divisions is composed of Harpalieiis having also the notch of the mentom one- 

 toothed, but of which the body is more or less ovoid or oval, and narrowed in front, with the labrum 

 entire, or slightly concave. These are the true Ilarpalus, Dejean, of wdhch one of tlie most common 

 species is the Harpalus cenms, Falir., about one-third of an inch long, of a shining black colour, with 

 tlie antenna; and legs yellowish, the upper siuface generally green or coppery, and very brilhant. It has 

 also been called Proteus, from tlie numberless changes in its colours. [The genus, even in its restricted 

 state, is very numerous, and requires revision. There appear to be se\eral Dritish species still uiule- 

 scrilied, in addition to the great number recorded by Stcpbcns, Curtis, &c.] 



The third of these di\isions is distinguished by the absence of a tooth in the notch of the mentum. 

 In other respects, however, it agrees with the preceding division. 



Ophonus, Zeigl., has the four anterior tarsi of the males strongly dilated, or evidently larger, and generally fur- 

 nished beneath with numerous hairs, forming a continuous brnsli. The penultimate joint is not bilobed, and the 

 nnocr surface of the body is linely punctured. ['I'liere are nunierous iinti^h species (including the UaipaJus 

 obsciint.^-, Fabr.), ciiietly found on the sea-coast.]
