the maxillary palpi suddenly terminated in a larg-e tnan;;iilar joint. Anihicus 2-puncfaius, Fab., placed in 

 this situation by Latreille, with doubt [and inserted by Eiii^dish Entoniolo<(ists near Latridius and other pesudo- 

 Xylopha2;a.] [The p;enera Carpujihngns and Mri/amcriiSy Macleay, are composed of New Holland insects, allied to 

 Sa'^ra.] 



The second tribe, Crloceriihs, is distinguished from the preceiling l)v the mnndibles having the tip 

 truncated, or with two or three teeth, and liy the tonguelet, which is either entire or but sbgbtly 

 notched. It is composed of tlic gcniis 



Crtoceris, Geotfr.^ 

 wliich we divide as follows : — 



Sometimes the mandibles are pointed, anil with two or three tcetli at the tips. The palpi are filiform. The 

 anteima^, of the ordinary thickness, are nearly monilifuriu in some, and composed ot reversed conical j'lints in 

 others, with the tips evidently thickened. 



Doriac/a, Fab. [Lcjitura, Linn.), has the posterior thii;hs lar^e and thickened ; the antenna? of equal thickness 

 tln-ua^,^hout ; the eyes entire, and the last joint of the tarsi almost entirely received between the lobes of the third 

 jnint, These insects are often brilliantly coloured, and bronzed or gWx. Many also exhibit a silky coating;-, which 

 must be useful to them when they fall into the water. They ordinarily live upon aquatic plants, as the Sa!2;ittaria, 

 NympliEEa, &c., upon which they take firm hold. It is in their roots that their larvee reside. Their pupre, according^ 

 to iM. A.Bron^niart, are attached to their filaments by only one side, and thus form knots or bulbs. The larv.-e are 

 naked and hidden, like those of the Leptnrida^. [The g-enus comprises a greiit number of British species,] 



rUvmonia, Meg-. [Macrophca of the British Catalo,«:ucs], are Donacia:-' with the penultimate joint of the tarsi 

 very small and nearly entire, and the last very long. [D. Eqidseti and Zostera;^ [rare British species]. 



Pttauristes, Latr., has the hind thighs larj,^e, but the eyes are notched ; the antenna composed of shorter joints, 

 ami the lobes of the third tarsal joint only recei\'ins' the base of the last joint. {Lenia varta, Fabr.] 



Crioceris proper [Lenta, Fabr.), differs from the preceding in having- the hind thighs scarcely ditfercnt from the 

 others. The anteimje are slightly thickened at the tips, and are nearly moniliform, the joints being scarcely 

 longer than thick ; the eyes are prominent and notched ; the hind part of tlie head forms a kind of neck. 



These insert.s live upon Liliacese, Asparagus, &c., and, like those of the preceding family, make a slight noise 

 A\fii-n srizrd. Tlndi- larvse feed upon the same plants, on which they take tirm hold by means of their six scaly 

 fci.'l. Tliey have the body soft, short, and swollen; their excrements are occasionally used by them to form a 

 cn\'(M-ing over tlie back, defending them from the action of the sun ; the anus is for this purpose placed upon the 

 back. They de>cend into the earth to become pupit. 



Criocvris iiifnl/o'^ra, the Lily Beetle, is three lines long, with the thorax and elytra red. It is found throughout 

 F.nrnpH upon llir; White Lily. M. Boudier has published some observations upon the French species, L. brunnea, 

 in the Memoirs 0/ the Linnaan Society of Paris. 



Crioceris Asparag'i, [the Asparagus Beetle, is of a smaller size], being blue, with the thorax red with a ^^pot in the 

 middle, and the elytra are yellowish white ■\\ith blue markings. [Its laiwa feeds upon the young sprigs of 

 as|iaragus, and sometimes does damage to the plants. See my memoir on this insect in the 

 Gardener''!,- Mnaazine.'] Cr. \2-pjinc(n(a, Linn., also feeds on this plant.

 thr sc\i-ii tci-iiiih;d joints of the antenna thickened, and the thorax with the sides dilated in the 

 middle— (Cy'/(;rr;-/.y sub.vpinosa, Fab-} 



Mcgascelis, DeJ., differs from the precedinii; in having the niaudibh.'S truncate ; the palpi termi- 

 nated by a swolirn truncate joint, with a small joint-like prolongation. The species are of small 

 size, and peculiar to South .Vnierica.

TIIE SIXTH FAMILY OF THE COLEOPTERA TETRA:\IERA,— 



Tl-IK CVCLICA,— 



Has aiso the under-side of the three basal joints of the tarsi spongy or pulvillose, the third being 

 hllobed, and the antennae filiform, or slightly thickened at the tips ; the body is also generally rounded, 

 with the base of the thorax as broad as the elytra in the species, few in nnnihcr, in which the body 

 isublong; the maxilla: have the outer lobe of a narrow fonn, nearly cylindrical and palpifortn, and 

 the inner lobe is broader, and without a scaly hook. Tlie tongneka is iieaHy sipiare, or oval ; entire, 

 or slightly eniarginate. .Ml the larvre with wliicli we arc acquainted arc furniiihrd with six feet ; the 

 body is :>ofr, coloured ; they feed like fhr perfect insect upon the leaves of diftVrcnt vegetables, wlicrc 

 lliry nrdinaiily alb\ thrm^rlves by a glulinniis secretion ; it is there also where many of tbcni become

 often varied in their colours. Other larvai enter the earth. 



These insects are generally of small size, often ornamented with metallic and lu-illiant colours, with 

 the body naked and without, hairs. They are generally slow in their motions, timid, and fall to the
