COLEOPTERA. , 499 



Carahtts Paykullii, Rossi. The species exclusively inhabit Spain, Italy, and the isles of the Mediterranean. 

 [The genus Feronia, as here described, is of very great extent, and on this account the characters which separate 

 tlie different groups of which it is composed (and which are considered by many writers as so many distinct 

 ganera) blend so into each other that it is almost impossible to assign their limits with precision. Hence Dejean 

 united them all into one genus, (for which Mr. Hope proposes the name of Thalia, Feronia having been long 

 previously used by Leach for a genus of Diptera,) although, in examining a local collection of small extent, as that 

 of England, the paucity of the number of species renders the assigning of characters apparently much more easy.] 



Myas, Zeigl., resembles Abax (Cheporus, Latr.) meiallicus ; but the thorax is more dilated at the sides, with a 

 slight notch in front of the posterior angles. M. chalybaus, Hungary. Here are also to be arranged the genera 

 Trigonotoma, Dej., formed of large Indian species, and Pseudomorpha, Kirby. 



Sometimes the mandibles are as long as the head, and the body always oblong. The first two genera resemble 

 Scarites, and the others Lebia. 



Cephalotes, Bon. (Broscus, Panz.), with the antennae not longer than half the body ; with short joints, and the 

 labrum entire. [Type, Carabtis cephalotes, Fabr.] 



Stomis, Clairv., with the antennre longer than half that of the body, with long joints, and the upper lip notched. 

 [Type, Stomis pumicatits, Clairv., a common British species.] 



Catascopus, Kirby, differs from the preceding in having the body flattened and broader, with the thorax 

 sliorter, the elytra strongly emarginated at the tips, and the upper lip elongated. The eyes are large and promi- 

 nent. They are of brilliant colours, and resemble at first sight Cicindel* or Elaphri. The species are from 

 India. Type, C. Harduickii, Kirby. The genus is closely allied to Pericalus, M'Leay, which have also the eyes 

 very prominent, but the proportion of the joints of the antenns is different. Type, P. cicindeloides, M'Leay ; Java. 



In a second subdivision, of much smaller extent, the length of the third joint of the antennae is triple that of the 

 preceding ; these organs and the legs being slender. 



Colpodes, M'Leay, has the four basal joints of the anterior tarsi of the males large, the penultimate being 

 bilobed. Type, C. brunneus, M'Leay ; Java. The others have the tarsal joints entire in both sexes. 



Mormolyce, Hagen., has the body very flat, like a withered leaf ; very much narrowed in front ; the head is very 

 long; the thorax oval, truncate at both ends ; the elytra are very greatly dilated, and curved on the outside with 

 a very deep notch at the tip. The only species, ill. phyllodes, Hagenb., is from Java. [It is one of the most sin- 

 gular of known Coleopterous insects. Its true relations are, however, to be found amongst the Truncatipennes, 

 as proved by the researches of Count Mannerheim and M. Servillc.] 



Sphodrus, Clairv., has the body depressed, but not foliaceous ; the head ovoid, and the elytra not laterally 

 dilated. Type, Carabus leucopthalmus, Linn. [A common British species, of large size.] 



The terminal Simplicimani are distinguished from all the others by the minute teeth on the under-side of the 

 ungues, at the tips of the tarsi. 



Pristonychus, Dej. {Ctenipus, Latr.), has the body elongated, with the thorax heart-shaped, truncate behind. 

 Types, Sphodrus janthinus and complanatus ; but this genus insensibly blends into the preceding. 



Calathus, Bon., has the body oval, arched above, and with the thorax square. Type, C. melanocephalus. Fab. 

 [A very abundant and pretty British species.] 



Taphria, Bon. {Symichus, Gyll.), differs from the preceding in having the labial palpi terminated in a mass like 

 a reversed cone, and the thorax nearly orbicular. Type, Carabus nivalis, Illig. 



5. The fifth section, Patellimani, is distinguished from the preceding only by the manner in which 

 the two anterior tarsi of the males are dilated, the basal joints (generally the first three in some, or 

 the first two only in others) being either square, or partially of this form, and the others in form of a 

 heart or reversed triangle, but always rounded at their extremity, and not terminated, as in the pre- 

 ceding sections, by acute angles, forming an orbicular or oblong plate, of which the under-side is most 

 commonly furnished with brashes of hairs, without any central naked space. The legs are commonly 

 long and slender, and the thorax is often more narrowed throughout its whole length than the abdo- 

 men. They frequent, for the most part, the sides of rivers, or other aquatic places. 



We divide the Patellimani into two divisions. In the first, the head is insensibly narrowed behind at 

 the base. Some of these have the mandibles always terminating in a point, and the plate of the [fore 

 male] tarsi is always narrow, elongated, and formed of the three basal joints, of which the second and 

 third are square. The labrum is entire, or without an e\'ident notch ; and one or two teeth in the 

 notch of the mentum. The following have the under-side of the tarsi furnished with two rows of 

 papilla, as in the preceding : — 



DoUchus, Bon., has the body very flat, and the tarsal claws are toothed beneath. The thorax is in the form of a 

 truncated heart. Type, Carabus Jiavicornis, Fabr. 



Platynus, Bon., similar to Dolichus in the form of the thorax, but with the ungues of the tarsi simple. The wings 

 are wanting, or are imperfect, in some species. Type, Carabus angusticollis, Fabr., [a common British species.] 



Agonum, Bon., has the thorax nearly orbicular. Type, Ilarpalus viduus, Gyll. and others ; [a common British 

 species.] 



Anchomenus, Bon., differs from the three preceding genera in having the body of the ordinary thickness, and 

 the thorax always in the shape of a truncated heart. Type, Carabus prasinus, Fabr. and others.
