MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 59 



specimens I am unable to place in the key, and I am leaving them 

 aside for the time being. The descriptions are brief but contain 

 the characters upon which my conclusions have been based. 



The record of TrogophJoeus corticlnm (Gravonhorst) from Guade- 

 loupe by Leng and Mutchler cannot be verified in tlie material avail- 

 able to me. It may be the same as the T. fulvi'penms Fauvel, but 

 I am unable to prove the identity of these two species. I have 

 omitted T. corticinus as a doubtful record. 



The name TrogopMoeus has long been used for this genus in spite 

 of the existence of the older name Carpelimus. In pointing out this 

 error Tottenham (1939, p. 227) uses the spelling CarpaUmus^ ap- 

 parently first used by Stephens in 1832. If this name was validated 

 by Samouelle, the original spelling nuist be accepted, in the absence 

 of i^roof that it was an error. The arrangement of subgenera is based 

 on the assignment of the genotypes in the Bernhauer and Schubert 

 catalog. 



I have examined over 1,500 examples of this genus from the West 

 Indies; 906 are in the British Museum, 63 in Dr. Cameron's collec- 

 tion, 131 in the Museum of Comparative Zoology, 27 in the American 

 Museum of Natural History, 142 in the United States National 

 Museum, and 367 were collected by me during 1935-37. These I 

 assign to 37 species, of which 18 appear to be new.
