[Many additional genera, allied to Harpaliis, liave l:ieen separated by Dejean, La])orte, Cliaudoir, 

 Erichson, and other continental Entomologists; hut they are, for tlie most part, founded upon, minute 

 structural characters, not requiring notice in this edition.] 



4. The fourth section, Simplicimani, approach the preceding in the manner in v\hich the elytra 

 are terminated ; but the two anterior tarsi are alone dilated in the males, without forming a square or 

 orbicular plate. Sometimes the first three joints are evidently larger, and the following is alwavs 

 much smaller than the preceding. Somrtimes this and the two preceding are broader, nearly equal, in 

 the shape of a in.-'art rc\ersed, or triangular. The liasal joints of the four succeeding tarsi arc slcndeier 

 and longer, nearly cylindrical, or in the shape of a long reversed cone. Some have the ungues of the 

 tarsi simple, or without teeth. 



In a first subdivision, of consideralde extent, the third joint of tin; antennre is at most as long again 

 as the preceding joint; the legs robust; and the thorax, in its lu'oadest jiart, as wide as the elytra. 

 Sometimes the mandibles are evidently shorter than the la-ad, and do not extend beyond the labrum 

 more than half their length. 



Wc commence with those which have all the outer palpi fdiform. 



Zabrus, BoneUi, has the last Joint of the maxillary palpi sensibly shorter than the preceding, and the two anterior 

 tibire are terminated by two spines. Type, Caratw^ (-//i^H^, Fabr., [a species of not very common occurrence in 

 tJiis country, and which lias been ascertained to feed upon o:rowin,i; corn]. 



Pogonus, Zeig;!., which in the natural order appears allied to Amara, has the two bn^aI joints alone, of the ante- 

 rior tarsi, dilated in the males, the basal joint beint>; the largest. The body is iiKne oblong. The^e insects appear 

 exclusively to inhabit tlie sea-coast, or the shores of salt water. [IJarpahis Inridipennis, Germar.] 



Tetragonoderiis, Dejean, has the anterior tarsi of the males proportionately less dilated than in the fjilowins". the 

 basal joints bein^ narrnwrr and nmre elongated, and rather in the shape nf a reversed cone than a lieart. They 

 are peculiar to South America, \liai pains circumfusm, Gerntar.] 



Feroiiia. Latr., has the anterior tarsi of the males, with the three first joints stron3;Iy dilated, ohcordate, with 

 tlie second and third rather transverse than longitudinal. 'Tliis subgenus comprises a great number of g-eneric 

 ;:'rouiis, indicated by Dejean in his Catalogue, \\hich are as follow: — Amara^ PtecUiis, Argittor, Omaseiis, Piafi/sDui, 

 P/ero-v/icIius, Ahax, Steropus, Pcrcii-i, Molops, and Cophonus. Dejean, however, having percci\'ed the difficulty of 

 characterizing them, united them all, with the exception of the first, into a great generical group, for which he re- 

 tained my najne Feroyiia. But as to Amara, I have in vain searched for characters to distinguish it from the 

 other genera. That derived from the tooth of the notch of the mentum, not to speak of its unimportance, is a very 

 e(|i.iiyi)ral rliaracter. This tiniih, in all these Carabici, appears to me tn lia\e a notch at its tip, but rather more 

 di.-tiiict and deep in sunn.' tljan ni others. The moniliform struetnrr ot' Hie antt-nuie Of some of the groups appears 

 111 me not to be assignable with precision to the limits of such gi-oups. I may say tlie same of the concavity of 

 ilie front margin of the labruni, and the form of the thorax. 



The FeronUe may be arranged in three sections. — 1st. The species generally winged, which lia\'e the body more 

 or less o\'al ; slightly convex or archeil above, with the antenna; more filiform ; the head proportionally narrowed, 

 ;:nrl tlin mandibles rather less.cxposrd. In their habits they appear to approach Zabrus and Hurpaius. Such are 

 .iuiara'^-, with Mm- thorax transverse ; I'lrri/ux, in wliirh it is nearly as long as broad, and the antennae are short, 

 wiMi tl]i_' Ihii-d jniiit compressed and angular; and Arr/i(f.or, similar to Pa-c'thi.s, bnt with longer antenna?, of 

 whieb tiic ibird jniiit is nr)t angiilati-d.— ■jud. The species generahy winged, but with the body straig] it, flat, or hori- 

 '/ontal al>o\r, and ilu' h^ad nearly as br'^ad. Such are Plaii/sma, Bon. ; to which we may unite that of Oi/m.s-r/is 

 and C Hi a lira mils, _Ma( I.— ;ird. The species analogous to the ijreceding in their general characters, but which dilfer 

 ni wanting wings. The majority of these have the thorax not uniformly cordate or truncate, and the elytra have 

 a transverse fold at the base. Sometimes the tlmrax is nearly square or truncate-cordate, with the posterior 

 angles acute ; {genera Copl/osus, Zeigl. ; C. r>/liinlriru.s-, Austria, having the body oblong, square, or cylindrical, 

 a.nd AOar, BonclU, having the body generally o\aK (ie|iressed, or sliiihtly convex — type. Car a bit. a xlriula, Fabr.,

 tliorax rounded, determinate the subgenus with species of large size, in which the thorax is always truncate-cor-
