The Pbytophagous Coleoptera of West Africa and in 

 particular of the Cameroons have up to the present never 

 been the subject of a special monograph to my knowledge. 

 Thomson in the Arch. ent. 1858 has perhaps contributed the 

 greater nurabers of species found in the Gaboon country. All 

 the -immerous species since described from that part of Africa 

 are distributed in any number of publications, too numerous 

 to mention; in one of the next numbers of the Stettiner En- 

 tom. Zeitschr. there will appear the descriptions of those spe- 

 cies obtained by Herr Conradt in the Cameroons, which have 

 been submitted to me for examination. In the present paper 

 I have given a list of those obtained by Prof. Sjöstedt in 

 the same locality with the description of the species which 

 seem to be new. West Africa has without doubt a perfectly 

 distinct fauna from that of other parts of the continent and 

 if properly explored will doubtless furnish yet a höst of new 

 and interesting species.
