500 . INSECTA. 



The following nave the under-side of the plate of the tarsi furnished with a close and continued brush. Tlie 

 outer palpi, and those of the labium, are terminated, in many, by a thicker or broader joint, like a reversed 

 triangle: — 



Callistiis, Bon., has the tooth of the mentum entire, and the outer palpi terminated by an oval joint, pointed at 

 'the tip. Type, Carahtis Iwiatiis, [a rare British species]. 



Oodes, Bon., ditfers in having the last joint of the outer maxillary palpi cylindrical, and of the labial palpi oval 

 and truncated. The thorax is trapezoidal, and narrowed in front. Type, Carabus helopiuides, Fabr. 



Chheiiius, Bon., has the tooth of the mentum bifid, the outer maxillary palpi terminated by a nearly cylindrical 

 joint, and the labial by a reversed conical and elongated joint. Carabus cinciiis, Fabr., and many others, belong 

 to this subgenus ; as does also the Carabus saponarius, Oliv., used in Senegal by the natives instead of soap. 



Epomis, Bon., has the outer palpi terminated by a broader compressed joint, in the shape of a hatchet, and is 

 most dilated in the males. The tooth of the mentum is always bifid. Type, E. circumscriptus, Dejean, and many 

 others. Dinodes and Lissauchetiius, M'Leay, also nearly approach Epomis. 



The others have generally the mandibles very obtuse and truncated, and bidentate at the tip. The upper lip is 

 distinctly bilobed, the notch of the mentum is not furnished with a tooth, and the dilated portion of the tarsi is 

 broad, and nearly orbicular. Some have the mandibles terminated in a point, without any notch or tooth near the 

 tip ; and the plate of the male tarsi is formed of the three basal joints. 



Rembus, Latr., has the upper lip bilobed ; the outer maxillary palpi nre filiform ; and the last joint of the labial 

 is slightly thickened, and in the form of a reversed cone. Type, Carabus polUus, Fabr. 



Vhwlus, Bon., has the upper lip merely emarginate, with a central impressed line. The last joint of the outer 

 palpi is nearly hatchet-shaped, and the body almost parallelepiped. The species are from America. 



Others have the mandibles very obtuse, notched at the tip, or with a tooth below it. 



Licinus, Latr., has the last joint of the outer palpi almost hatchet-shaped. The plate of the male tarsi is broad 

 and suborbicular, formed of the two basal joints. Type, Carabus silphoides, Fabr. ; C. depressus, PaykuU : [rare 

 British species]. 



Badister, Clairv. (AmblycMs, Gyll.), has the last joint of the outer palpi oval ; that of the labial palpi is slightly 

 longer, and often pointed. The plate of the male tarsi is long and square, formed of the three basal joints. Type, 

 Carabus bipustulatus, Fabr., [a common British species]. 



In the second division of the Patellimani, the head is narrowed suddenly behind the eyes, as though 

 attached to the thorax by a peduncle. It is often small, with the eyes prominent. 



Pe/ccium, Kiiby, has not a tooth in the notch of the mentum ; the mandibles are robust, and the upper lip nearly 

 bilobed. The four basal joints of the anterior male tarsi are in the shape of a reversed triangle. Type, P. cyanipes, 

 Kirby ; South America. In the following, there is a tooth in the notch of the mentum, and the upper lip is nearly 

 straight. 



Cynthia, Latr., has the outer palpi terminated by a hatchet-shaped joint. The head is small, and the basal 

 joints of the male tarsi are of a reversed triangular form. Founded upon a Brazilian species, having the appear- 

 ance of Abax. 



Panagceus, Latr., has the tarsal plate of the males formed only of the two basal joints. The head is very small, 

 with the eyes globular. The parts of the mouth are also very small, and the thorax often suborbicular. Type, 

 Carabus Crux major, Fabr., [a rare British species]. 



In the two following subgenera, the outer palpi are filiform : — 



Loricera, Latr., is very remarkable, having the second and four following joints of the antennae furnished with 

 strong bristles. The maxillae are bearded on the outside, the labial palpi are longer than the ma.xillary, and the 

 three basal joints of the fore tarsi are dilated in the males. Type, L. cenea, Latr. (Carabus pilicornis, Fabr.), [a 

 very common British insect]. 



Patrobus, Megerle, has the antennae filiform, straight, and without whorls of hairs ; the mandibles are of the 

 ordinary size; the length of the labial palpi does not exceed that of the maxillary; the two basal joints of the 

 anterior tarsi are alone dilated in the males. Type, Carabus rujipcs, Fabr., [a species very abundant on the 

 summit of Snowdon, and other high mountains]. 



We now pass to those Carabiques which have the anterior tibiae destitute of a notch on the inside ; 

 or which, if they do exhibit one, commences very near the tip of these tibiae, or does not extend upon 

 the fore face, but forms only an oblique and linear canal. The tonguelet is often A/ery short, termi- 

 nated in a point in the middle of the tip, and furnished with paraglossa;, also pointed. The mandibles 

 are robust. The last joint of the outer palpi is generally very large, compressed in the form of a re- 

 versed triangle or hatchet in some, or nearly spoon-shaped in others, and often more swollen in the 

 males (Procerus). The eyes are very prominent ; the elytra are entire, or simply sinnated at the 

 posterior extremity ; and the abdomen is generally voluminous, compared to the rest of the body. 

 These Carabiques are, for the most part, of large size, ornamented with brilliant metallic colours. They 

 run very quickly, and are very carnivorous. They constitute a peculiar section (the sixth) in the group, 

 and which we name Grandipalpi. 



Those which have the body robust and wingless, with a bilobed labrum, the last joint of the outer 

 palpi always very large, the notch of the mentum without a tooth, the inner edge of the mandibles
