INSECTA. 



Apoderns, distinct by the head affixed to the thorax by a rotiile. 



A:ji/.<:, iidi the head immersed to the eyes in the thorax. 



RhyncJiite.s, has the proboscis dihited at the tip, and the abdomen nearly square, 

 R. Bacchus [a splendid but very rare British species], lives on the vine, the larvae 

 inhabiting^ the rolled-up leaves, which it devoui-s, and thus sometimes commits 

 preat damage. 



.■ipion, Herbst., has the bndy pear-shaped. See the mono,i2japhs of Germar and 

 Kirby, in Trans. Linn. >Soc., vol. xii. [Some of the species do much damag"e, 

 devouring- the seeds of clover.] 



lifiinotia, Kirby [2ic/us, Sch.], lias the body almost linear, and the anteiinEe 

 thirkened, but not clubbed. 



Eurh'iiiu.'i, Kirby, has the antenna' terminated by a long mass, the last joint 

 being greatly elongate*! in the males. 



Tubiccnus, Dej. {Auletes, Sch.), has the antenna- terminated by a perfoliated 

 mass, and the abdomen is oldong. 



Those \vlilch have the antennae riliforui, ^vith the la^t jiiiut alone forming the mass, the proboscis 

 often longer in the males than in the females, and often differently terminated, and always stretched 

 out in front, tlie body elongated, and the penultimate tarsal joint bilobed, compose the genus^ 



Brentus, Fab. {Curcuiio, Linn.) 



Tliese irjsects are peculiar to warm climates. Some of them, whicl) ha^e the body linear, and the antennselibfurm, 

 and 11 -join ted, form the subgenus 



Bmifiis (uupii-r, Liun., which has Ijeen greatly cut u|") by Scbonherr. From the statements of Sa\i andLacurdaire, 

 it appears that these species are always found beneath the bark of trees ; the only European species is the Brcntas 

 it aliens. 



Vlocerus, Schon-, has the body linear, and the antenna; ll-jijinted. 



Cj/!iis, Latr., has only 10-jointed, and the thorax nodose. 



Sometimes the antennae are distinctly elbowed, the basal joint being much longer than the following. 

 These form the genus Curcuiio, Linn. 



We divide them into Brevirostres and Lou^'iroslres, according as the antennas are inserted — near the 

 ti[) of the rostum, close to the mandibles, — or further back, either near the middle or at the base. 



The L rev iro-s-f res form, according to Fahricius, two genera, [IJracJ/i/cerus and Curcidio]. 



BuACHYCERUS, Fabr.— 

 Has all the joints of the tarsi entire, without cushions beneath ; the antennae are short, scarcely elbowed, and only 

 y-jointed, the last forming the mass ; they want wings ; the body is very rugose, or unequal. They are peculiar to 

 the south of Europe and Africa, living on the ground in sandy places, and appearing early in the s[iring. According 

 to M. Cailiiaud, the Ethiopian women suspend one of the species round their necks as an amulet. 



CURCULTO, — 



Has nearly all the under-side of the tarsi cushioned, and tlie pcnultiinate joint biiubed. The antenna' are U 

 or 12-jointcd, comprising the false Joint by which they are sometimes terminated. Although here much more re- 

 stricted than in the Linn.Tan system, this genus comprises an immense number of species, particularly described 

 by Schonherr and Germar, wdio have greatly divided it. They may be divided, according to our own til_)ser\ations, 

 into two principal divisions. 



1. Those in which the mcnturn, more or less orbicular, occupies all the oral ca\'ity, and hides the maxilla; and 

 mandibles, which are not distinctly toothed. 



Ci/chmiis, (including' Schonherr's Cri/ptops, Deracanthas, and Jnn/cfcrii.-i), has the tarsi not puhillose, and the 

 penultimate joint scarcely bilobed. In all the rest the tarsi are pulvillose, and the penultimate joint bilobed. 



CitrcHlio proper (including a very great number of genera of Schonhei'r), is winged, and has the lateral imiircs- 

 sions of the rostrum oblique, and directed downwards; the fore legs scarcely dilTer from the rest. The South 

 American species, forming the genera Entimus, Chlorimn, &c., are remarkable for their splendour, and often for 

 their size. The Diamond Beetle, {Curcuiio impcriaJis,) is one of them. Other small species peculiar to our climate, 

 of a much smaller size, but scarcely less splendid, [especially under alens,j and of a silvery or gn-en colour, form the 

 genus Polydrusus, Schonherr, Curc.sericcus, micans, Betuld;,^c. 



Lfpfosomus, Sch., has the head very long behind, the rostrum very short, the thorax subcylindic, and the elytra 

 juoduced into two divergent spines. A single species, C. acuminaius, Fabr. New Holland. 



Lcj'tocerus, (including many of Schonherr's genera), differs in having the fore-legs elongated, the tibice curved, 

 the thighs thick and spined, and the tarsi often dilated and ciliated ; the antennx arc long and slender. (Chlelly 

 Brazilian species.) 



Phyllohius (including also many other genera of Schonherr), is winged, but the rostral fossnla is straiglit and 

 short. 



The Brevirostres with the penultimate joint of the tarsi bilobed, the wings wanting, as well as (lie scntellum 

 form various other genera, such as Otiorh/jchus, Omias, Pachyrhij/tclius, Psalidiia/i, lliiilacilcs, Sij:'/ffaps 

 Ili/p/iautus, Sic.
