300 CLASS INSECTA. 



The srenus Calltcerus of M. Gravenhorst is unknown to 

 me. That of Stexosthetus, of M. Megerle, indicated in 

 the catalogue of the collection of Coleoptera of M. le Comte 

 Dejean, presents all the characters of a true Pselaphus, and 

 ought to be suppressed. Such is also at present the opinion 

 of this last naturalist.
