a short distance. If pursued they have recourse to the same means 

 of escape. 



The larvae of the two species indigenous to France, the only ones 

 that have been observed, excavate in the earth a deep cylindrical 

 hole, an operation which they effect with their mandibles and feet. 

 To empty it, they place the detached particles on their head, turn 

 about, climb up the ascent little by little, resting at intervals and 

 clinging to the walls of their domicil by means of their two dorsal 

 mammillae; when they arrive at the mouth of the aperture they throw 

 down their burden. While in ambuscade, the plate of their head, 

 exactly closes the entrance of their cell, and is on a level with the 

 ground. They seize their prey with their mandibles, and even dart 

 upon it, and by a see-saw motion of their head precipitate it to the 

 bottom of the hole. Thither also they quickly retreat on the least 

 intimation of danger. If they are too confined, or the soil is not of 

 a proper nature, they construct a new habitation elsewhere. Such 

 is their voracity that they devour other larvae of the same species, 

 which have taken up their abode in their vicinity. When about to 

 change their tegument or to become pupae, they close the opening of 

 their cell. Part of these observations were communicated to me 

 by the late M. Miger, who had carefully studied many larvae of 

 Coleoptera, and discovered several which had escaped the researches 

 of naturalists. 



C. cartipestris, L.; Panz., Faun. Insect. Germ. LXXXV, iii. 

 About six lines in length; grass-green above; labrum white, 

 slightly unidentated in the middle; five white points on each 

 elytra. Very common in Europe in the spring. 



C. hybrida, L.; Panz., lb., iv. Two crescent-shaped spots, 

 and a white band on each elytron; one of the spots at the exte- 

 rior base and the other at the end; suture cupreous. In sand- 

 pits, never mixing with the campestris(l). The 



C. germanica and some other species have a narrower and 

 more elongated form, and seem to constitute a particular sec-
