^^G INSECTA. 



RhinosimiiS, Latr. {Salpingus, I!H^.). lias tlie antenna:; terminated by an elongated mass, formed of three or five 

 joints ; the muzzle very-flat, -with a produced ang-le on each side before the tip. They reside beneath the bark of trees, 

 and reiiiiire in a natural order to be arranged near to Aiiflirihn.s of Fabricias, by -whom indeed they were united 

 therewith. The body is depressed and the palpi tliicker at the tipis. [.S. ruburi.s, a pretty minute liritiah species.] 



Our second general division, — 



THE FOURTH FAMILY OF THE COLEOPTERA IIETEROMERA,— 

 The Tr,\chelides, — 

 Have the head trianLrular or heart-shaped, carried on a kind of neek, \vhich, heing as wide as tlie 

 front of the thorax, prevents it from being immersed therein up to the eyes ; the body is often soft, 

 ■with the elytra flexible, not striated, and often very short, one partially lapping over the other ; the 

 niaxiUie are never hooked ; the tar-al joints are entire, an<l the ungues bifid. The majority live in 

 the perfect state upon dilfercnt vegetables, devouring the leaves or sucking the honey of the tlo^\'ers : 

 many, wlien seized, depress the head, and contract the feet, as if they were dead ; others are very active. 



AVe divide this family into six tribes, formingthc same nunilier of genera. Tbe first tribe, i^y^n'aWcp, 

 has the bo<ly elongated, narrower in front than beliiinl, with thu thorax eitlier sulicylindric or square, or 

 oMiid and truncated ; the antennae inserted near a notch of tlic eyes, simple, filiform, or thickened gra- 

 dually to the tips ; generally moniliform, with the last joint longer than the preceding in the males ; 

 the paljii thickened at the tips, and the last joint of the maxillary palpi long and tiiangular ; the tibiae 

 long and narrow ; the two anterior curved ; the penultimate joint of the tarsi bilobed, and the ungues 

 neither bifid nor toothed. The indigenous species inhabit woods, and are found upon different vegetables ; 

 the body is soft, the elytra flexible, and, like the Cantharides and Meloes, they feign death when taken. 



Lai/r/ii pnijicr, is composed of specieswhich liave the antennae gradually thickened, and partly or entirely moni- 

 lifnjiu, tlic la:^t juiiit ovoid or oval, the head scarcely advanced in front, and tlie thorax subcylindric or square. 

 [L. hirtn, a very common British insect, of small size ; fmmd in hed^a-s, in which also I have fuund its larva-, 

 which is hairy, with the^extremity of the body bifid.) 



S^a/Zra, Latr., is formed of exotic species resembliiiK the j^enus A;;Ta ; prolonged in front, and suddenly nar- 

 rowed behind the eyes. 



Ilemipepltis, Latr., doubtfully lielongin^a; to this tribe, has the antenna' filiform, short, ami elbowed, the body 

 linear and depressed, and the head heart-shaped. 



The second tribe, Pyrochroides, approaches the preceding in respect of the tarsi, the length and 

 slcndirncss of the anterior part of the body, which is however depressed, with the tliorax nearly orbi- 

 cular or trapezoidal ; the antenniE, at least in the males, are pectinated or feathered ; the maxillary palpi 

 are hut slightly serrated, and terminated by a subsecuriform joint; the labial filiform ; the abdomen 

 elongate, eatirely covered by the elytra, and rounded behind. Thoy arc found in the spring in woods, the 

 larvae li\ing beneath the bark of trees ; they form the genus — 



Pyrochroa, Geoffr. 



De/idroidfs, Latr., has long feathery branches to the antennrc. (Exotic species.) 

 Pvroc/n-o(7proper,hastheantenna: simply pectinated. [Pi/roc/ima ru/'c/is, ^yery abnmlnnt 

 British species, of a scarlet colour, with black legs and antenna;.] 



The third trilic, }for(Ir//oinf. although not distinguished by any constant cha- 

 racter, derived frnm the tar^i. ungues, antenna-, or jialpi, is easily to he distinguished 

 by the general form of the body, elevated and arciied, with the head low, Ihe tho- 

 rax trapezoid or senii»'ii'cnlar, the elytra very short, or narrow and })ointrd at the 

 tips, as well as tbe abdomen. In llieir antcnme, many approaeli the l'\ rochroides ; 

 '''■'■ '^^,?i7r '"'"' otiiers, in their maxilla:, ungues, tarsi, and jiarasitic liahits, are allied to Nemognathai 

 and Silaris, subgenera of the last tribe of this family, but they are removed from both by their extreme 

 agility, and the firm texture of tlieir integuments. They form the genus — 



MORrii':m.,\, Linn. 

 Some liave ibe palpi of urip'pial thickness throu;^-hout, the antennte of the males strongly pectinated or fan- 

 shaped, tbe cxtreiniiy of tlie mandibles not notched, and tbe tarsal ungues denticulated. 



Ripip/iorutiy Bosc, has the wings extended beyond the elytra, which are as long as the abdomen ; the tarsal un- 

 gues bifid ; the antennse strongly Aipectinated in the moles, ?//;7'serrateti in the females. Some naturalists have 

 fniinil in the nests of the common Wasp, many living individuals of the [Knglish species], Ilipiplioriis junadoxus 

 \\liicb lias been the'iice interred to be parasitic in tlie larv-i state in such sitiiatienis. Nevevtlielrss, fnun anol)ser-
