Notes on previously described Species. 



Crioceris australis, Jacoby, P. Z. S. 1876, p. 807. 



This species, described by me in 1876, is (as a comparison with the 

 type in the British-Museum collection, of the existence of which I was 

 previously not aware, has convinced me) the true C. nigripes of 

 Fabricius. Lacordaire's description of that species (vol. i. p. 573), 

 which I took as a guide, and which made me believe that the insect 

 before me was a different species, is totally at variance with the insect 

 of Fabricius ; and my description is therefore the right one, although 

 the name australis must stand as a synonym.
