The Harris specimens are in the collection of the Boston society, num- 

 bered 32. They are undoubtedly what Mr. Grotehas named clarescens 

 in American collections, but which Mr. Butler shows is not Gueuee's 

 species. As Mr. Grote's determination is incorrect, the species is 

 nameless and Dr. Harris's name becomes available.
