344 INSECTA. 



elongated, almost cylindrical, or in the form of an elongated and reversed 

 cone. 



The genera are Zabrux, Pogonus, Feronia, &c. 



5. The PATELLIMANI, distinguished from the Simplicimani, by the manner 

 in which the two anterior tarsi of the males are dilated, the first joints 

 usually the three first, then the fourth, and sometimes only the two first all 

 of which are sometimes square, and at others only in part, the remainder 

 being cordiform, or resembling a reversed triangle, but always rounded at 

 their extremity, and not terminated as in the preceding sections by acute 

 angles, form an orbicular palette or long square, the inferior surface of which 

 is usually furnished with brushes or crowded papillte, without any intermediate 

 vacancy. 



The legs are generally slender and elongated, and the thorax is frequently 

 narrower than the abdomen, throughout its whole length. Most of them 

 frequent the shores of rivers, or other aquatic localities. 



The genera are, Dolichus, Agonus, Chkenius, DicaBlus, &c. &c. 



6. The GRANDIPALPI, whose anterior tibiae have no emargination on the 

 internal side, or which present one that begins close to their extremity, or 

 that does not extend on their anterior face, and forming a mere oblique and 

 linear canal. The ligula is often extremely short, terminated in a point in the 

 middle of its summit, and accompanied by pointed paraglossae. The mandibles 

 are robust. The last joint of the exterior palpi is usually larger, compressed 

 into the form of a reversed triangle, or securiform in some, and almost into 

 that of a spoon in others. The eyes are prominent. The elytra are entire 

 or simply sinuous at their posterior extremity. The abdomen, compared with 

 the other parts of the body, is voluminous. They are generally large insects, 

 are ornamented with brilliant metallic colours, run very fast, and are extremely 

 carnivorous. 



In this section we have Paniborus, Cychrus, Scaphinotut, Proccrus, Calasunut, 

 and 



CARABUS, Linnceus, Fabricius, 



Or Carabus properly so called. The labrum is simply ernarginatc or bilobate; 

 tooth of the emargination of the mentum entire. 



Count Dejean describes one hundred and twenty-four species, which he has 

 arranged in sixteen divisions. The first thirteen comprise those whose elytra 

 are convex or arched, and the three last those in which they are plane. 



The greater number of these species inhabit urope, Caucasus, Siberia, Asia 

 Minor, Syria, and the north of Africa to the thirtieth degree of north lati- 

 tude. Some few are also found at the two extremities of America, and it is 

 probable that others may be found in the intermediate mountains*. 



Of the species that inhabit North America, we have as yet only discovered the 

 C. Beauvoisi, carinatus, Lherminier ?, Kneatopunctatus (serratus, Say), sylvosus and 

 vinctus. The mountains of New Hampshire, and Maine particularly,- probably contain 

 several others, and it is to he hoped that some friend of the science, within reach of those 

 localities, will soon enable us to enlarge our catalogue of this interesting genus, as well as 

 that of others found in the same localities. Am. Ed.
