During the East African expedition of Mr. Cliaiiler and Licntenant 

 von Hobiiel, ill 1893 from the coast to Hameye, along- the River Tana, 

 149 species of Coleoptera were collected. In 1894, on their exj^edi- 

 tion to Jonibene Range, northeast of Mount Kenia, the same gentlemen 

 collected 4") species, out of wliich only three ])roved identical with those 

 obtained on their first expedition. It nu^y be of interest to publish a 

 systematic list of these si)ecies, with descriptions of such new forms, 

 34 in number, that apparently have not yet been classified in entomo- 

 logical literature. In four instances it has been found necessary to 

 erect new genera.
