ON THE care:s'ides (FAM. CARABID^) 



No. III.* 

 By Thomas G. Sloanb. 



In the present paper twenty new species are added to the 

 Carenides, several of which are remarkable and isolated species 

 which can hardly be placed with any of those previously described; 

 such are Carenuin reflexum, C. acutipes^ C pulchrum^ Eutoma (?) 

 aherrans and Neocarenum spenceri. The discovery of so many 

 peculiar species helps to show how far we are still from a complete 

 knowledge of the many varying forms which exist among Care- 

 nides, and leads to the belief that any classification of the tribe 

 made with the data at present available must be looked upon as 

 merely provisional. 



A considerable amount of confusion is found among writers on 

 the Carenides with regard to the terms applied to certain parts 

 of the head; therefore it seems necessary to attempt a more exact 

 definition of at least some of the features used in describing 

 species, and for the sake of uniformity the terms employed by me 

 for various parts of the head in the genus Clivina are now 

 suggested for the same features in the Carenides. 



The cfypeus. — In Clivina the clypeus may be divided into three 

 parts,! two of which, viz., the median part and the wings, may 

 be used among the Carenides. The median part is immediately 

 behind the labrum; it is usually defined on each side by a more 

 or less prominent triangular projection {intermediate angles of 

 the clypeus); in the genus Scaraphites the intermediate angles are 

 obsolete.
