534 INSECTA. 



Chrysomela, Ceranil)yx, and Cantharis. In the first edition of this work, I had united the whole into 

 one genus, tielops, but their internal as well as external anatomy indicates that this family constitutes 

 five trihes, composed of the same number of genera, namely, Helops, Cintela^ DirccEa, Fabr., (Edam&ra, 

 and Mycferus, Oliv. In respect to their digestive organs and other cliaracters, lielops and Cistela ap- 

 proach Tcnehrin ; hut the Cistelai have the nianiiibles entire, ami gcnorallv live amongst leaves and 

 flowers, in which respect they differ from llcli)ps ; the majority of the iJirca^u lia\e the faculty to 

 leap, and the iienultimate joint of the tar^i is !)hid in many. Some live in fungi, &c., and others in 

 rotten wood. These are allied on one iiau<l tu lielops, and ou the otlier to CEdemera, and especially to 

 Nothns, Ijclongiiig to the same trilie. Sucli are the principles upon which 1 have distributed this familv. 



Those which have the antennas inserted near the eyes, and the head not produced into a long muzzle, 

 form the first four triljes, [^Helojjii, CisteUdes, Serropalpides, and (Edemerites']. 



The Helopii have the antenna covered at the base by the margin of the head, nearly fihform, or 

 slightly thickened at the tip; generally composed of ueuily cylindrical joints, the terminal one being 

 always the longest; the extremity of the mamiildcs is liifid ; the last joint of the maxillary palpi is 

 largest, and hatchet-shaped; the eyes ohlong, and kidney-siiapcd : none of the legs are formed for 

 leaping; the pcnnliimare joint of the tarsi is either entire or not deeply bilob(d; the ungues entire ; 

 the body often arcbcil above, and of a solid consistence; the larva?, so far as known, are filiform, 

 smooth, and shining, w ith very short feet like those of the Tenebrionidrc ; tliey are found in olil wood ; 

 the perfecL in3.eets are also met with beneath the bark. This tribe nearlv corresponds with tlie genus 



IIklops, Fal>r. 



Epitragusy Latr. (Iiavin,2; tlie base of the maxillae hidden by the mentum), 



Cnodalon, Latr. {w ith the head narro" er than tlie thorax), and 



Camps/a, Lepel. and Serv. {Camaria, L. & S., with the head as bioad as the liind part of the thorax), are American 

 g'roups, huvino; the hinder extremity of the presternum produced into a small point, received inta a notch of the 

 mesosternuni. In all the other Helopii the mesosternura is not notched, nor the prosternum pointed. 



Spheniiciis, Kirb>' (IJrazilian insects, havins; the appearance of Erotyli), 



Acanthopus, Me^^ (with the fore thi<,^hs thick and toothed, A. dentipes, Germany), 



Aman/gmtis, Dahn. (with simple fore-leg's and antennae), 



Spharotm, Kirliy (with the thorax narrower throui^hont than the aljdonien, and with simple antennae and 

 slender tibiw), and 



Adelium, Kn-hy (be ins: of an oval forTO, w itli the thorax nearly orbicular, comjiosed of Xew Hob and insects), have 

 the body nearly ovoid or stiort, with the thorax trunsverse. [Xone of titese sub^^enera occur in this country.] 



He/ops proper, has the thorax transverse, scarcely as lon^; as wide, and ch^sely applied to the base of the elytra, 

 //. cteruleiis, lanipes, and caraboides, [British insects, the last being exceedingly abuinlant]. 



Lana has the last Joint of the antenna thicker than the preceding, and ovoid, the thorax truncate-corda[e, 

 separated from the abdomen by a visible space ; antei-ioi" femora thickened. [European species of small size.] 



The following Helopii have the body long and narrow, the tlior;ix nearly sipmre, or truncate-cordate. 



^tetiotracbehtti, Latr. (Dnjops, Pk.), with the heail naiTOwed behind into a neck, the three terminal joints of 

 tlie antenna-' short and thick. D. tjcnea, Payk. [u continental species]. 



Aiiuathus dfcoratu.s, Germar, appears to approach the last very closely, as lioes also Pi'hnaiopi's IIi/mmr!ii, Fisch. 



,S(ro>igi/liu/n, K., anil Stvnochin^ K., ha\e tlie head not narrowed into a neck, and the terminal joints of the 

 antenna scarcely dillVring from the preceding, [liiazilian insects, mostly gaily coloured.] 



Pi/f/to, Latr., has the body flattened and the thorax narrowed behind. [P. dej)resi-(is, found in tlie north of Europe. 

 The larva is very flat.] 



The second tribe, Cisielides, is exceedingly close to the preceding, but the antenna; are not concealed 

 at the base ; the mandibles are entire ; the tarsal ungues denticulated : many of these insects live in 

 This tribe b>rms the genus 



CiS'ri':LA, Fabr. 

 , Latr., has the thorax thick, narrow, and suborbicular. [Brazilian insects.] 



(.'/slfla proper, has the thorax depressed trapezoid, the head produced into a short nuizzle, the 

 aiitriiiial joints mostly serrated, and the body ovoid or oval. 



L'islria rerainboides, five lines long; black, with orange-coloured, striated elytra; the larva 

 residrs it) tlie decomposed wood of the oak. 



Miirrfiii-hares, Latr. {iVi/cefo/dilhi, Gyll.), has the head not produced into a mnzzle, and the 

 body narrow and elongated. JJ. harbatus. 



AH.'nihi, Fabr., differs from the preceding in having the penultimate jointof the tarsi hilobed, 

 and tlic last joint of the maxillary pal])! hatchet-shaped. 



[M. Sober has revised this tribe, and added several new genera, in the Annales dc In Soc'uie 

 Enlomol. de France.]
