XXVI. — On the names Promecoderus, Cnemacanthus and 

 Odontoscelis, as applied to certain genera of Carabideous 

 Insects. By G. R. Waterhouse, Esq., Curator to the 

 Zoological Society of London. 



To the Editors of the Annals and Magazine of Natural History. 



Gentlemen, 

 You will oblige me by inserting in the f Annals' the follow- 

 ing observations upon some remarks contained in the c Revue 

 Zoologique.' In that periodical I am accused of adopting a 

 generic name given by one of my own countrymen in prefer- 

 ence to one previously given to the same group by a French 

 entomologist. It is stated that " M. Waterhouse, par un 

 esprit national que nous devons respecter, a adopte le nora de 

 Odontoscelis, Curtis, de preference a celui de Cnemacanthus, 

 Brulle, quoique ce dernier fut bien anterieur." 



This is the first time I have been accused of this esprit 

 national, which M. Reiche considers ne serait rien moins 

 que respectable*. These remarks I should not have noticed, 

 but the editor of the e Revue' has inserted a kind of defence 

 of my proceedings, giving me an opening for escape on the 

 score of ignorance of certain facts, which facts however, 

 strange to say, were first pointed out by myself in the very 

 paper in which I am supposed to have committed myself. 



It would be supposed from what has been stated, that the 

 name Cnemacanthus originated with M. Brulle ; it so happens 



* M. Reiche endeavours to exonerate me from the charge, for which I 

 owe him many thanks, though I do not consider he has succeeded in the 

 attempt.
