vation of M. Farines, the larva of the two-spotted Ripiphorus lives and undergoes its changes in the stalk of 
the Eryngium campestre. 
Myodites, Latr. {Ripidius, Thunb.), has the wings also extended, but the elytra are very short ; the antennae arc 
very strongly feathered ; the tarsal claws are toothed. 
I Pelccotomay Fisch., has also the tarsal claws toothed, but the wings [and abdomen] are entirely covered by the 
j elytra. [Exotic insects, of moderate size.] In the others the palpi are terminated by a large hatchet-shaped 
I joint ; the mandibles are bifid at the tips, and the antennae of the males are only serrated. 
Mordella, Linn., has the antennae of equal thickness throughout, and slightly serrated in the males ; the eyes are 
I not emarginate, [and the abdomen is terminated by a long point. M. aculeata, Linn., and many other small 
I British species]. 
1 Anaspis, Geoffr., has the antennae simple, and rather thickened to the tips, the eyes notched, [and the abdomen 
j not pointed]. A. frontalis [and numerous other minute British insects], 
I The fourth tribe, Anthicides, possesses simple or but slightly serrated and filiform antennae, or but little 
thickened at the tips ; the joints very nearly alike, except the last, which is rather longer, and oval ; the 
maxillary palpi are terminated by a hatchet-shaped joint ; the penultimate joint of the tarsi is bilobed ; the 
I body narrower in front, with the eyes entire or scarcely emarginate. Some of these species are found 
[ upon plants, but the majority live on the ground, and run with great quickness : their larvae are probably 
j parasites. They compose the genus, — 
' Notoxus, Geoffr. 
i Soraptia, Latr., has the thorax nearly semicircular, and the antennas inserted in a notch of the eyes, filiform. 
They haveagreat analogy with Mordella, Cistela, &c., in their form. {S.fusca, a minute British species.) 
j Steropes, Stev. {Blasfanus, Illig.), has the antennae terminated by three long joints. 
Notoxus proper, has the antennae gradually thickened, the joints conical, and the thorax of a reversed ovoid form, 
narrowed, and truncated behind, or divided into two globose knots. Some species [to which English Entomologists 
i restrict the name Notoxus], have the thorax produced into a horn over the head. N. monoceros, Linn, [a small 
British species found in sand banks]. Those with the thorax unarmed [form the restricted genus Anthicus of En- 
1 glish authors. A.fuscus, and many other minute species], some of which are apterous. 
' The two following tribes, which terminate the Heteromera, have several characters in common: 
i mandibles terminated by a simple point ; palpi filiform, or but slightly thickened at the tips ; abdomen 
I soft ; elytra flexible ; possessing vesicatory powers ; ungues generally bifid. In the perfect state, many of 
I them are herbivorous ; but many amongst them are parasites whilst larvas. 
I The fifth tribe, Horiales, differs from the succeeding by having the ungues denticulated, and furnished 
I with a seta ; and the antennse are filiform, not longer than the thorax ; the labrum small ; mandibles 
; strong and exposed ; palpi filiform ; thorax square, and the two hind legs very robust, at least in one sex. 
I The transformations of Horia maculata are described in the Trans. Linn. Son. of London, [by the kte 
I I Lansdown Guilding]. The larva destroys that of a large Carpenter Bee {Xylocopa teredo, which 
j makes its nest in the trucks of trees in St. Vincents) : this is effected, as the author supposes, by the 
ji larva of the beetle devouring the provisions laid up in store for the larva of the Xylocopa, which is of 
j course starved to death. This tribe is composed of the genus — 
j HoRiA,Fabr,,— 
I Species of which inhabit the intertropical parts of South America, and East India. 
! Cissites, Latr., has the head narrower than the thorax, and the posterior femora greatly thickened. 
The sixth and last tribe, or the Vesicatory Beetles {Cantharidice), is distinguished from the preceding 
by the tarsal ungues, which are very deeply divided, so as to appear double ; the head is generally 
large, broad, and rounded behind ; the thorax is generally narrowed behind, approaching the shape of 
a truneated heart ; in others it is nearly orbicular ; the elytra are often slightly inclined at the sides ; 
they counterfeit death when seized, and many at such times emit a yellowish liquid from the joints of 
the feet, which is caustic, and of a penetrating odour, the organs for the secretion of whieh have not 
been observed. Several species {Meloe, Mylahris, Cantharis,) are employed externally as vesicants, and 
internally as a powerful stimulant ; the latter is however very dangerous in its application. 
This tribe is formed of the genus — 
Meloe, Linn., — 
Which has been divided into various others. The anatomical researches of Messrs. L^on Dufour and Bretonneau 
upon the epipastic powers of these insects, enable us to arrange these generic groups in a natural order, only slightly 
differing from that already adopted. The latter has discovered that Sitaris does not possess this property ; it also 
resembles Zonitis in its general structure, and the latter are contiguous to Cantharis. These insects therefore
