COLEOPTERA. 501 



toothed tlirougliout, or neai'ly tliroLigliout, its whole length, compose a first division, consisting of the 

 following suligentra: — 



Pamhorus, L:itr., has the mandibles curved, and strong-ly toothed throughout the whole leng-th ; and the outside 

 of the tibialis produced at the tip into a puiut. Tlie last joint of the outer palpi is semi-oval and lonofitudinal. P. 

 allernans, Latr., from New Holland. [Several other spcciey are described in a monograph by M. Gory, in Guerin's 

 Iliujasin de Zoologic.'] 



C'^f/z/vw, Latr., has the mandibles straight, and simply curved at the tip; the anterior tibiae are not produced 

 into a point at the tip ; the tarsi are alike in botn sexes ; the thorax is in the form of a truncated heart, or nearly 

 orbicular, with the posterior angles obsolete. [Type, C rosira'.us, Fabr. ; a not uncommon British species.] 



iScaphinotm; Latr., has the three basal joints of the fore tarsi of the males dilated but slightly, and in the 

 form of a plate ; the tliorax trapeziform and broad, with the posterior angles acute, and turned upwards. Cychrus 

 cli'vatus, Fabr.; North America. 



iSyy/dcrotftfr?/.?, Dejean, has the aspect of Cychrus; but with the two basal joints of the anterior male tai'si very 

 broad, and forming a broad plate. \_f<. Lcconiei, Dejean ; North America.] 



[Dr. Harris has just published (1839) a memoir on Cychrus in the Boston Nat. Hist. Sac. Traiisaclions, in which 

 he suggests that the dilTerent genera separated therefrom ought to be expunged.] 



A second division is formed of those species which have also the body robust, generally wingless, but 

 with the iiientum furnished with an entire or bifid tootli, and the mandibles armed with one or two 

 toelh situated at the base ; the tliorax is in the form of a truncated heart; the abdomen is often 

 oval. 



Ti'Qln-s, Leach, has the labrum entire, and the tursi are alike in both sexes. T. Megerlei, nearly tivo inches 

 long. From the coast of Guinea. The last joint of the maxillary palpi is very large, and hatchet-shaped. [M. 

 Brulle has removed this genus to the group containing Punaga^us, with which it agrees in the majority of its 

 characters.] 



Procerus^ Meg., has the labrum bilobed, with the tarsi alike in both sexes. Carabus scabrosus, Fabr. &c. 



All these species are of large size, entirely black or blue, or green above, with the elyti'a very much chagrined. 

 They inhabit the mountains of the east of Europe, Caucasus, Libanus, &:c. 



Procrustes, Bon., has the labrum bilobed, and the tooth of the notch of the mentum bifid ; the fore tarsi of the 

 males is dilated. Carabu^s cor'iaceus, [a reputed British species]. 



Carabus, Linn. {Tac/ii/pus, Web.), has the labrum simply notched or bilobed, and with the tooth of the rnentura- 

 notch entire; the fore tarsi dilated in the males; they are destitute of wings. ^ 



Didcan describes one hundred and twenty-four species, divided into sixteen sec- '^<^, / 



tiuns. The majority of these species inhabit Europe, Caucasus, Siberia, Asia 

 Minor, Syria, and the north of Africa. Some have been brought from the two 

 extremities of America ; and it is probable that the intermediate countries possess 

 others. Carabus nwrrt^H-?, Linn., Panz., is a common continental species, which 

 has received the ordinary name of the Gardener, [being found in gardens, where 

 it feeds upon AVorms. There are nearly twenty British species, the nomenclature 

 of several of which is very confused in its synonymes. One of the largest 

 and best characterized species is C. clatlirafus, a rare Irish insect, here figured.] 



Cotosoma, Weber {Callisthenes, Fischer), is generally winged ; the mandibles are ^ 

 without distinct teeth on the inner edge; the thorax is transverse, equally dilated t 

 and rounded at the sides, without elongated posterior angles; the abdomen is 

 nearly square ; the four posterior tibiK are curved in the males of several. The 

 species are fewer than in Carabus, but they extend from the north to the equator. 

 Type, Carabus sycophanta, Linn., three-fourths of an inch long, of a velvet blacky 



with the elytra golden green, or brilliant copper, very finely striated, each having ^.^ 54 -Carabus dathratus. 

 three lines of fine im[)ressed dots. Its larva lives in the nests of the processionary 



Caterpillars, upon which it feeds, devouring many in the course of a day. Other larvs of its own species, smaller 

 and younger, attack and devour it when its voracity has overcome its activity. They are black ; and are some- 

 times found running on the ground, or upon trees, especially the oak. [An elaborate anatomical memoir upon 

 this larva, by Dr. Hermann Burmeister, is published in the Transactions of the Entomological Society, in the last 

 part of which Mr. Hope has also published the descriptions of sume species brought home by Mr. Charles Darwin, 

 the celebrated naturalist of the expedition of the Beagle.] 



A third and last division of the Grandipaljn is at once distinguished from the former by a series of 

 characters. The majority are winged ; the basal joints of the fore tarsi of the males are always 

 dilated ; the labrum is entire ; the outer palpi are very slightly dilated at the tips ; the inner edge of 

 the maudildes is not armed with distinct teeth ; and the tooth of the mentum-notch is bifid. The fore 

 tibiae of manv species have a short notch at the inner side, where one of the spines is inserted higher 

 than the other : so that these Carabiques, as well as those of the following section, might come imme- 

 diatelv after the Patcllimani. They generally frequent humid and aquatic places. Some of thenn, 

 such as Ouiophroa, seem to unite this tribe with the following, or the aquatic carnivorous species.
