COLEOPTEUA. 49 



- 



toothed on the outside nor bidigitate at the tips, and tne second joint of the antenna: is evidently shorter than the 

 following. They nearly approach, in the organs of the month, the two lust subgenera; and have been con/bun 

 by some writers, with Scarites, of which they have the appearance. 



Morio, Latr. (with the antenna of equal length throughout, thighs oval, and tibiae triangular, Harpuhu monili- 

 cornis, Latr. &c), and Oztena, Oliv. (with the auteni « thickened at the tips, and the femora and tibia narrow and 

 elongated, Oztena dentipes, 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 marly oval or fusiform, and the labium notched, compose the remaining genera. 



Ditomus, bonelli, have the palpi shorter than the head, the thorax cup or heart-shaped, and the tarsi short. 

 Some species, to which Zeigler restricts the generic name, have 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 AHstus, Zeigl., have the body shorter, broader in front, and the bead and thorax nearly continuous. 



Apotomus, Hoffm., have the anterior palpi verj long, the thorax orbicular, and the tarsi filiform and elongated. 

 Type, Scarites ru/ut, Oliv. [South of Europe.] 



[The typical insects of this section, from the observations of M. Lefebvre de Cerisy, appear to be 

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

 species arc chiefly inhabitants of the Old World. They burrow in the earth, ot sand of the sea-shore, 

 for which their palmated fore-legs well lit them. They are insects of prey, lurking by day in holes 

 and under stones, and feeding at night upon Melolonthide, 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 QuADRlMANl, or II arpaliens of Dejcan— 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 Ophonus) furnished with two rows of papilla; or scales, with a broad space between. The 

 body is always winged, generally oval, and arched or convex above, with the thorax broader than long, 

 or at most nearly isometrical; the head is never suddenly narrowed behind; the antennas are of equal 

 thickness throughout, or but very slightly thickened towards the tips; the mandibles are not very 

 strong; the tooth in the notch of the mentum is always entire, but it is wanting in some Bpecies; the 

 tongueht is truncated at the tip, and accompanied by two ear-like membranous paraglossaj ; the legs 

 are robust, and the ungues of the tarsi simple ; the intermediate tarsi, as in the females, are short, and, 

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



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

 Harpahts, as restricted by Bonelli. New groups have since still further diminished its extent. They 

 consist of the three following divisions : — 



The first of these divisions has for its characters, — notch of the mentum with a single tooth, labium 

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



Acinopus, Zeigl., with filiform antenna;, the joints short but cylindrical, the thorax narrowed gradually from 

 the front to the back, and the binder angles very obtuse. Type, Harpalut megacephalus, Latr. [South of Burope.] 



Daptus, Fischer, with the antenna moniliform after the fifth joint, and the thorax narrowed Buddenlj towards 

 the posterior angles, which are pointed. Type, D. pictut, Fischer: Russia. Pangus, Megerlc (P. p< ntylvanlau), 

 does not appear to me to differ essentially from Daptus. 



The second of these divisions is composed of Ilarpalicns having also the notch of the mentum - 



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

 entire, or slightly concave. These are the true Harpahts, Dejcan, of which .me ot the most common 

 Bpei ies is the Harpahu emeus, Fabr., about one-third of an inch long, of a shining black colour, with 

 the antenna; and legs yellowish, the upper surface generally green or coppery, and very brilliant II 

 also been called Proteus, from the numberless changes in its colours. [The g< aus,( ven in its n stricted 

 Btate, is verj numerous, and requires revision. There appear to be Beveral British species still unde- 

 ied, in addition to the great number recorded bj Stephens, Curtis, &c 

 The third of these divisions 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 strongl) dilated, orevidentlj larger, and generally fur- 

 nishe I beneath with numerous hairs, forming a continuous brush. The penultimate joint is not bilobed, and the 

 uoncr surface of the bod] is finely punctun I ere are numerous British Harpahu
