 II, xxi, A., From eight to ten lines in length; violet black; 

 elytra golden-green or brilliant cupreotis, and finely striated, 

 each with three series of impressed and distant points. 



Its larva inhabits the nest of the processionary caterpillars, on 

 which it feeds, consuming several Of them in the course of a 

 day; Avhen filled to satiety, it loses all activity, and other larvae 

 of the same species attack and devour it'. It is black, and 

 frequently found running about on the ground or trees, particu- 

 larly the oak(l). 

 The third and last division of the Grandipalpi presents an ensem- 

 ble of characters which clearly distinguishes it from the preceding 

 ones. Most of the species that compose it are winged. The ante- 

 rior tarsi of the ftiales are always dilated. 'I'he labrum is entire. 

 The exterior palpi are merely somewhat dilated or thicker at the 

 extremity, with the last joint in the form of a reversed and elon- 

 gated cone. The internal side of the mandibles presents no tooth 

 worthy of notice; that in the middle of the emargination of the 

 mentum is bifid. The middle of the superior margin of the ligula 

 is elevated into a point. On the internal side of the anterior tibiae 

 of several is a short emargination, or one of the two spurs is inserted 

 higher than the other, so that in this respect these Carabici are 

 ambiguous, and might be placed, as well as those of the ensuing sec- 

 tion, directly after the Patellimani(2). They usually frequent wet 

 places. Some of them, such as Omophron, appear to connect this 

 tribe with the following one or the Aquatic Carnivora. 



Some, in which the body is flattened, or convex and suborbicular, 

 are provided with eyes of an ordinary size; their antennae are linear 

 and generally consist of elongated and almost cylindrical joints; the 

 external sides of the maxillae are bearded, and the two internal spines 

 of the two anterior tibiae on a level at their origin; these tibiae 

 merely have a simple longitudinal canal. *> 



Sometimes the body is a flattened oblong oval, with a cordiform 

 and truncated thorax posteriorly narrowed. The scutellum is dis-

 Sayi and scrutator. Count Dejean is mistaken in supposing the calidum to be a 

 common species — it is rare even in the south, where, I believe, it is only to be 

 found The Sayi is very common. Am. Ed.]
