Notes on the above Species, 



1. Nifjro-olivncca, Dours. This is a well-known species. 

 I need only refer to Schmiedeknecht's full description of 

 it in Apidte Europ?eoe, p. 560. The specimens examined 

 are from Spain (coll, Friese), Algiers, and North Italy. 



2. Livens, Perez. (Melliferes de Barbarie, p. 39.) I 

 have examined a $ determined by the author, and both 

 sexes in the collection of Mr. E. Saunders (taken in 

 Algeria by the Rev. A. E. Eaton). Dr. Schmiedeknecht 

 has kindly communicated to me both sexes from Tunis
