554 INSECTA. 



THE SEVENTH FAMILY OF THE COLEOPTEKA TETRAMERA,— 

 The Clavipat.i'i, — 

 Is dLStinguislied from all tlie others of tlic same section, \vliich, like these, have the underside of llic 

 three hasal joints of the tarsi furnished "with cushions beneath, and tlie third joint hihilicd, (the ter- 

 minal joint also having a node at its hase, which is also observed in the Cocrinelhe,) by having tlieir 

 antennae terminated by a very distinct and perfoliated mass, and by their maxillie being armed on the 

 inner edge with a horny tooth ; in a few, the tarsi are entire, but they recede from the other Telrainera 

 which have similar tarsi, by having the body nearly globular, and contractile into a ball. The body is 

 often of a rounded form, generally very gibbose and hemispherical, with the antennae shorter than the 

 body ; the mandibles notched or toothed at the extremity ; the palpi terminated by a much thicker joint ; 

 the last joint of the maxillary palpi being very broad, compressed, and nearly crescent-shaped. The 

 form of the organs of the mouth indicates that the species are not carnivorous : the indigenous species 

 are, in fact, found in fungi growing on the trunks of trees, beneath the bark, ^c. 

 Tliey may be reunited into the single genus 



EiiOTYLUS, F;ilir. — 

 Some of wliicli have the the maxillary palpi ternunated by a larii-e liatchet- or crescent-shaped joint. 



Erofi/liis proper (incladiiio; -.£^f/*?//;«A', Fabr.), has the intermediate Joints of the anteniuT subcylindric, and the 

 club of the antennae formed of the terminal joints, oblong: ; the inner and corneous lobe of the maxillae havinfr 

 two teeth. The species are contined to South America. [They are very numerous, a considerable number ha\inj; 

 been described by M. Godart in his monog:raph on this p^enus.] 



Triplax {and Tritoma, Fabr.), differ in havin^f the antennre submoniliform, and terminated by a shorter ovoid 

 club, and by the maxilh-e having^ a sino;le small tooth on the inner edg'e. In Tritoma, the body is nearly iiemisphe- 

 rical — T. bipH^tHlittnm [a small British speries, of rare occurrence on funi;i],— and in Tripla.v, the body is oval, or 

 oblong. [Several small Biiti>b species.] Tbe utiiers have the last joint of tlie maxillary palpi eluii;,^ated, and nioi*e 

 or less oval. 



Launiiria, I.atr., has the liody linear, and the club of the antenuie [3- to] 5-jointed. [Exotic insects, havinj? 

 somewhat tin,' apijearauce ni I'ilaterid^e.] 



Phalacrus, Payk. {Anhoioma, Illi^.), has the body sub-hemispherical, and the club of the antenna; only 3-jointed. 

 The species [are very luunerous, and of small size. They are found upon flowers, and beneath the bark of trees]. 



Agaf/iid/inii, IWv^. {Anis'ihjtiui, Fabr.), diflers from all the rest of the family by havin,^ all the juints of the tarsi 

 simple, and the body nearly t^luimlar. [Minute BiiUsh siiecies.] 



The fourth section of the Coleoptera. tluit of the Tiumi-:ra, has only three [onliiiary-sized] 

 joints in tin.' tarsi; [a fnuidli, however, but very minute, exists at the hase of the last or fourth 

 jttint]. TTie\- compose three fannlies ; those of the iirst two are elosuly allied to the hist of the 

 Tetramera. Their antenntc, always composed of eleven joints*, are terminated i)y a club 

 formed of the last three, compressed, and of a conical or reversed triangular form. The basal 

 jonit of thr tarsi is always distinct ; the second joint ordniarily bilobed, and the lastj preseutin^^ 

 a knot at its base, is always terminated by two ungues; the elytra entirely cover the abdomen, 

 and are not truncatefh The last of the Trimera, or the third family, approach in this respect, 

 and in many «dber eharaetcis, the pentamcrons Ptraehelytra, and some others (d' the same 

 section, siicli as MnsCiyiis, Sci/thiia'inis, and have habits very ditt'erent from those of the other 

 Triniera. 



THE FIRST FA^HLY OF THE COLEOPTERA TRIMERA,— 

 Trih: FuNGicoi.-i'., — 

 Have the antenna? longer than tlie head and thcrrax ; the l.iody oval, with the thorax trapezoid ; the 

 maxillary palpi filiform, or rather thickened at the tips, but not terminated by a very large hatchet- 

 sha|»ed joint ; the penultimate joint of the tarsi is always deeply bilobed. This family may be reduced 

 to the single genus 



EuMORiM-ies, — 

 Some of which have the third juint of the antenna- much lonj^cr than the preceding- and followine:. Such are 

 Eumorphus, Weber, wlucb li:is the cluli of the antennas suddenly formed, solid, and very compressed ; the max-
