502 INSECTA, 
Some have the eyes of ordinary size, tlie antennae linear, with elongated joints, and the two spurs of the fore 
tibiae close together,— the tibiae having only a longitudinal canal. 
Pogonopliorus, Latr. {Leishis, Froehl., Manticora, Panz.), is remarkable for the elongation of the outer palpi, 
and the labial ones, which are longer than the head; the mandibles are bulg'ed out into a flat angle at the base 
outside, and the tonguelet is terminated by three spines. Type, Carabus spinibarbis, Fabr., [a common British 
species.] 
Nebria, Latr., differs from the preceding in the palpi being much shorter ; the outside of the mandibles is 
scarcely dilated, the tonguelet is short. Type, Carabus brevicollis. [One of the most abundant species.] 
Alpmis, Bon., are apterous Nebriae, merely more oblong, and which frequent high mountains. Carabus Hell- 
wigii, Panz. 
Omophron, Latr. (Scolgtus, Fabr.), differs from the three preceding in having the body gibbose above, and nearly 
orbicular; the thorax very short, transverse, and the scutellum is not visible. This subgenus is composed of a 
small number of species found on the margin of waters in Europe, North America, Egypt, and the Cape of Good 
Hope. M. Desmarest has described the larva of the common species, [<S. limbatum, Latr., found on the border of 
streams in France.] This larva approaches that of the Dytici in its form. 
The remainder of this division have the body thick, with large prominent eyes ; antennae rather thickened at 
the tips, with short joints ; one of the spurs of the fore tibiae is inserted above the other; the four or three basal 
joints of the anterior tarsi of the males are but slightly dilated in the majority. These insects are found on the 
banks of rivers in Europe and Siberia. 
Blethisa, Bon., has the thorax broader than long, nearly square, being only slightly narrowed near the posterior 
angles, with the four basal joints of the Carabus multipunctatus, Fabr., Panz. 
PelopMla, Dej., has the three basal joints of the fore tarsi of the males strongly dilated. Carabus borealis, Yabr., 
[a species recently detected in Ireland], 
Elaphrus, Fabr., has the thorax at least as long as it is broad, convex and heart-sliaped ; the four basal joints 
of the fore tarsi of the males slightly dilated. 
Carabus uliginosus, Fabr., four lines long, has the elytra ornamented with deep circular impressions running 
into each other, with an elevated disc. 
Cicindela riparia, Linn., is another common British species, smaller than the preceding 
Dum., diifers from the preceding in having the labrum nearly semicircular, (instead of short and 
transverse,) and the outer palpi are terminated by a suboval joint pointed at the tip; the tarsi are alike in both 
sexes. Cicindela aquatica, Linn., [a very common British species found on the banks of streams and in damp 
situations, running about with very great agility. Mr. Waterhouse has published a monogi’aph on the genus in 
the Entomological Magazine, where he has described eighteen British species ; but subsequent Coleopterists have 
greatly reduced the number of the species.] 
Our second general division of this tribe, the Subulipalpi, is distinguished by the form of the outer 
palpi, of which the penultimate joint is in the form of a reversed cone, and is united to the following, 
with which it forms an oval or spindle-shaped mass, terminated in a point. The two anterior tibiae 
are always notched. These insects closely resemble the last, both in their form and habits. 
Bembidion,l&iY. {Bembidium, GyW.), has the penultimate joint of the outer maxillary palpi swollen, and the 
last very slender and conical. The basal joint of the two anterior male tarsi is dilated in the males. Messrs. 
Ziegler and Megerle divided this subgenus into several others, but without giving their characters ; founding 
them, as it seems, entirely on the change of form of the thorax. These are Tachypus, Bembidium, Lopha, Nota- 
phus, Peryphus, and Leia, [the last of which (being previously used for a genus of Diptera) has been changed by 
Stephens into Philochthus.'] The type given by Latreille (considered by Dejean as a Tachypus) is the Cicindela 
flavipes, Linn., one-fifth of aline long, a very abundant species. [This genus comprises a considerable number of 
species, all of which are of very small size, being the most minute of all the Carabiques, and generally of brassy 
or coppery tints. Another pretty species is the Cicindela quadri-maculaia, Linn. ; of a brassy colour, with four 
white spots on the elytra.] 
Trechus, Clairv., has the last joint and the outer palpi as long or longer than the preceding, and as thick at its f 
base, so that together they form a fusiform mass. Trechus rubens, Clairv., masoreus, Zeigl., is allied to Ti-echus, | 
with palpi fusiform at the tip, but with the penultimate joint shorter than the following ; the fore tarsi of the males 
is slightly dilated. Harpaleis collares, Gyil., Blanius, Zeigl., is composed of narrowed Trechi with the thorax of a 
reversed-triangular form, and mandibles proportionably larger, and extending beyond the labrum. 
[In terminating the terrestrial carnivorous Beetles, it is necessary again to refer to the many works 
recently published, containing either isolated descriptions or more complete monographs of these ‘ 
insects. Dejean, King, Hope, Kirby, Gory, Laporte, Bridle, Erichson, Mannerheim, and many other 
recent Entomologists have devoted their attention to this tribe, many seeming to prefer them from 
the circumstance of their standing at the head of the order. Some of them have cut up the several 
groups given by Latreille into a great number of smaller groups, for which they have retained the 
family names terminating in idee. It is of course impossible to give any synopsis, or even notice, of 
the many generic or subgeneric groups Avhich have been proposed, chiefly founded upon exotic insects, 
of which nothing is known except their existence as cabinet specimens,] I
