COLEOPTERA. 535 



The third tribe, Serropalpiden, is distinguished by the maxillary palpi being serrated, very large, and 

 drooping ; the antenna; are inserted in a notch of the eye, often short and filiform ; t lie mandibles are 

 generally bifid at the tip, and the tarsal ungues simple ; the front of the head is not produced, and the hind 

 thighs are not thickened, in which they differ from the following; the penultimate joint of the tarsi, of the 

 four fore-feet at least, is bilobed, and in those in which it is entire, the hind feet are fitted for leaping, 

 being long, compressed, with slender tarsi. This tribe has for its type the genus — 



Dikc.ka, Fabr. 



Orcfiesia, Latr., differs from the rest in having the antennae clavate, the maxillary palpi terminated by a hatchet- 

 shaped joint, and the hind feet are formed for leaping. [O. micans, Latr., a minute British .species.] 



EustrophtU, flligf. (with the body ovoid, and the airtenna: shorter than the thorax), and 



lltil/omenits, I'ayk. (with the body elongate oval, and the antenna; longer than the thorax), have the palpi but 

 slightly thickened at the tip. The remainder have the body narrow and elongated, with the maxillary palpi hat- 

 chet-shaped, and some of these have the antenna; thick and short. 



Dirccea proper (Xyitta, l'ayk.), has the maxillary palpi not serrated, the antenna; thick, the body oval-shaped, 

 and the scutellum very small. 



Melnndrya, Fabr., with the maxillary palpi evidently serrated, the thorax depressed at the sides, and the 

 scutellmn moderate-sized. [M. carahoides, a common British species.] 



IIi/puliis, Pk., has the body narrow and nearly linear, with the thorax oblongand narrow behind. D. qucrctnut, 

 [a very rare British species]. 



Serropalpu/:, Hellw., has the antenna; slender, subcylindric, the body of a firm consistence, and the maxillary 

 palpi strongly serrated. 



Berropalpus, Gyll., differs from the last in having the body soft, the maxillary palpi scarcely serrated, and the 

 penultimate joint of the tarsi bilobed. [Two very rare British species.] 



The fourth tribe, (Edemeriten, is nearly alKed to the preceding in the insertion of the antennae, bifid 

 mandibles, bilobed penultimate joint of the tarsi, and securiform maxillary palpi ; but (with the excep- 

 tion of Notkus, which, although nearly allied to some of the preceding, differs in having the hind 

 femora thickened) exhibits a series of characters which does not allow them to be confounded with 

 any other Ileteromera. The body is long, narrow, nearly linear, with the head and thorax rather nar- 

 rower than the elytra ; the antennae are longer than these parts of the body, serrated in some, but 

 composed of long cylindric joints in the others ; the anterior extremity of the head is more or less 

 produced into a short muzzle, with the eyes more prominent ; the thorax is at least as long as broad, 

 nearly square or cylindrical ; the elytra are linear, narrowed behind, and often flexible. These insects 

 are related to the Telephori and Zonitcs. They are found in flowers or trees ; their metamorphoses 

 are not known. They form a single genus, — 



CEdemera, Ohv 



2V0fAi»,Zeigl. (Osphya, Illig), has the antenna; short, simple, and inserted in a notch in the eyes ; the hind thighs 

 thickened in one sex, the thorax as broad as the base of the abdomen, and the tarsal claws bifid. [.V. clarifies, a 

 very rare insect, found in Huntingdonshire.] 



Rfuebut, Fischer, ought probably in a natural system to be placed here. 



Calupus, Fab., has the antenna; very long and serrated, the hind legs simple, with the Second joint very short 

 C. terratUornit, [a common continental species]. 



Sparedrus, Megerle, differs from CaJopus in having the antennae simple. 



DytUut, lis. Ii., has the antenna; also filiform, inserted in front of the eyes ; the elytra are nut narrowed at the 

 tips. 1). helopioidet, [a continental species]. 



CBdemera, Oliv , has the hind legs thickened in one sex, the antenna- Ion; and slender in one sex, and the 

 elytra very much narrowed at the tips. [(Ed. carulea,* very common British insect. Several of the species 

 have been separated as distinct subgenera by Stephens.] 



The fifth and last tribe of the Stenelytra, that of the R/ii/nrosfoma, is composed of insects some of 

 which are nearly allied to the (Edcmcritcs, whilst the others appear to belong in a natural order 

 to the family of the Weevils [Rhyncophora). The head is evidently prolonged in front, in the shape of 

 a muzzle or flattened rostrum, having the antenna; at its base and in front of the eyes, which ureal* 

 wavs entire. These insects form a single genus 



MvcTF.ars,— 

 Some of which have the antenna- filiform, and the nvuszll not dilated at the tip. 



Stenottoma, Latr. {LepUera, fabr.), has the bod] narrow, the thorax conical, truncal., i, the elytra IsadbsBj nsr- 

 rowed to a point. (/■:</. rortrata, Latr., South of Boro] i 



Myetenu, ClairV., has the body OVOid, solid, silky, [with the elytra entire] ; the anlenn.e appear to be 12-jomted.
