This fine species is unique in the magnificent collection of 

 M. le Comte Dejean, who informs me that he now possesses 

 between 20,000 and 21,000 species of Coleoptera. It is there-,

 tunity of acknowledging my thanks to that distinguished ento- 

 mologist for the kindness with which he allowed me to make use 

 not only of this, but of various other valuable portions of his 

 collections.
