518 INSECTA. 



The followinLT Jiavi? the three liasal joints of the tarsi, nt least in tlio males short, broad, and bilobed, (lie fourth 

 being very small and scarcely apparent, with the maxillary palpi filiforni. 



Jps, Fab., having the body oval-ol>Ion^^ depressed, with the posterior extremity of the body exposed, and wilh 

 one of the mandibles (the left) truncated and tridentate at the tip, and the other broadly notched. [The species are 

 mostly small, of a black colour, with reil spots on the elytra.] 



Niiidirln, Fab. {Strong<iliix, Herbst.), have both the mandibles narrowed at the tip and terminated in a bifid point. 

 Some are tiattened, oblon;;, or ovoid, others orbicular and ^^ibbose, or proportionately more convex than the pre- 

 ceding. N. cenca, Fabr., is fonnd very abundantly in flowers : it is very small, of a sliininf:: bronzed .^"reen colour, 

 with the antennu-e black, and thr fr.-t lirownish lilack or fulvous. [N. grnra is one of the commonest British 

 ^ ^ species, Iari;-er th;in the precediiifj;, and generally found under tlie bark of willow-treos, where 



I^S* •^>JY^-v,;h'' its larva also resides.] 

 J ^ ' v \ Cercus, Latr. iC"ffirrr/r.\, Herb.st.), differs from the two preeedins' in haviup; the second and 



/njHnjill] K third joints of the antcnri;f; nearly of equal size, the club elonf2;ated and pear-shaped, [and not 

 ^ suddenly formed and orbicular or oval); the body is depressed, and the elytra are truncate. 



[Very small species, found in flowers.] 

 Byturus, Latr., differs from all the preceding' by haviuix the tibi:e loni^:, narrow, and nearly 

 Fitr- 64.— \it. gTUc.t linear, the elytra covering the body, and not truncated at tliC tip, the body oval, and the club 

 of the antennae oblong. [B. tomfutosus, a small species of very common occurrence, the larva of which feeds in 

 the interior of ripe raspberries.] 



The sixth tribe, Engkhtes, agrees with the last in having the tnamlihles notched at the tip, l)ut differs 

 ill these organs scarcely extending beyond tlie sides uf the lalirani ; the body is ova] or elliptic, with 

 the anterior extremitv id" the licad slightly advanced into an (l^t^s^e point. Tlic tarsi have li\e dj^tinct 

 joints (some male Crvptuphagi excepted, wlijcli arc betenniierous), entire, and merely sbgbrly viiluse 

 beneath ; the penultimate joint is but a little shorter than the preceding, the antenna?, terminate in a per- 

 foliated mass nf '.\ joinis, the elytra entirely cover the abdomen, the palpi arc slightly thickened at the 

 tii)s. Some of the species, of very small size, live in the interior of houses. These Claviconics may be 



muted into a single geims, 



Pacne. 



Dacne, Latr. {Eiigis, Fabr), has the antenna? terminated suddenly in a large orbicular, or ovoid, and compressed 

 close mass. 



(Jryjifo/ih'tiv's, Herb:?t., has the antenna: nioniliform, with the second joint as large or larger than the preceding, 

 and terminated less suddenly by a narrower club witli more distinct joints. [Minute domestic insects.] 



Anflit'i-opJiagus, Knoch, has the antenna.* proportionably tincker, composed of transverse joints, and terminated 

 gradually by a club, the second and the eighth jdints being ui-arly c(pial-sized. 



Triph!iUu.s, Meg., Dej., differs only from Cryptophagus in the nuTuber of the joints of the tarsi. 

 AVe now jiass to some tribes liaving the prosternum often dUated in front like a eravat, and w-bich 

 diftVr from the preceding in having the feet ujore or less contractile, the tibia; being folded against the 

 thighs, even though the tarsi may lie free. The maniiibles are short, thick, and toothed, tin; body is 

 ovoid, thick, and clothed with scales, or hairs, easily abraded, which give it a diversilicd cobmr. The 

 larv;e ate hairy, and feed fur the must part on (he skins or carcases of animals, many of them being 

 very injurious in coUeeiuins nf insects. Sucb of them as have not the feet perfectly euntraetile, the 

 tai'si rcjoaining free, with the tibiae long ami narrow, form our seventh tribe, Dennculini, and the genus 



DEHMESTii:s, Linn. 



A.'iphlijilnu-iix, Z''igl., has only tm distinct joints in the antenna', the palpi very short, and the body orbicular. 

 Kitltlnla orbiciilala, Gylb, [a minute liritish species]. 



The following have eleven distinct joints in the antenna', and fhf palpi are liliforTn, or thickened at the tips. 

 Some of tliese have the antenna^'uot received in particular ruvities nn the undcr-siile of the thiu-ax. 



Dcrnn:-:tr.s prnprr, h;i^ tb'; auti-unffi smaller in both sexes ; the length of the terminal joint scarcely exceeding 

 that of the pn-crdnig. SiMne of tlii'se insects commit great ravages in fur-warehouses, cabinets of natural history, 

 &c., D. hinlarhia gnawing to piee<.-s the inseets in cullectiuns into which it may hap|ien to nud^e its way ; others 

 fi.'Cd upon carcasr;,s. 



DermcstesIanbu-iHS, Linn., is black, with the base of tlie el> tra gray spotted with black ; its 

 la-va is long, gradually narrowed from the front to the extremity of the body ; dark brown 

 aiiove, white bi^nrath, with long hairs, and two horny hooks on the last segment of the body. 



Miui'ihunii, llcrlp.-.f., Ii;is tlie cinliuC the antenna: greatly elongated in the males, the last 

 jnint of a laurrnlatr birni. 1). ji.-lliii, Linn., is 'l\ lines long, black, with three white spots on 

 the thorax, and one on each eh tra. Its larva is \ery long, red brown, shining, with red hairs, 

 tliose of the extremity of the body forming a tail. 



Liiiinirhus, Zeigl., difiers from the last two subgenera in having the antcniiii: gradually 

 clubbed ; tliey are granular, and are lodged uudrr the antei ior angles of the tlauax ; tbe labial 

 paliM are very small. Byn-liKu serirctis, Dufts.
