ORDER COLEOPTERA. 235 



Those are for the most part winged. Their mandibles are 

 striated transversely, without perceptible teeth on the inter- 

 nal side. The corslet is transverse, equally dilated and 

 rounded laterally, without elongations at the posterior angles. 

 The abdomen is almost squared. Their external palpi are 

 less dilated at their extremity. The second articulation of 

 the antennas is short, and the third elongated. The four 

 hinder legs are arched in many of the males. 



Calosoma, Web. Fab. Calosoma, Callisthenes, Fischer. 



This sub-genus is much less numerous than the preceding, 

 but its species extend from the north to the equator. 



Carabus Sycophantha, Lin. Clairv. Entom. Helv. II. 

 xxi. A. 



From eight to ten lines in length, of a violet black, with 

 the elytra of a golden green, or very brilliant copper colour, 

 very finely striated, and having each three lines of little deep 

 and distant points. 



Its larva lives in the nest oi processionary caterpillars, on 

 which it feeds. It will eat a great number of them in one 

 day. Some other larvae of its own species, as yet young and 

 small, attack and devour it, when by dint of having gorman- 

 dized it has lost its activity. They are black, and are some- 

 times found running on the ground, or on trees, and more 

 especially on the oak.*
