This rare species was discovered in Peru by Mr. Jelski. I 

 think it is unique in the Museum of Varsovia. In my opinion 

 it may turn out to be only a variety of E. cupreiventris.

This rare species was discovered in Bolivia, by the celebrated 

 Naturalist, d'Orbigny. It was dedicated to him, by Messrs. 

 Mulsant and Bourcier, but having been described eight years 

 before by d'Orbigny and Lafrernaye under the name of 

 Ornismya glaucopoides^ this name has the priority.
