The individuals from the Ural and 8outh Russia wliicli we have e.xaiuiiied do 

 not seem to ns to be difFcrent from the examples of Central and Western Enrojie. 

 Dr. Staudinger, I.e., described as cinerascens a Sonth Kussian individual which he 

 considered to represent a desert form. This individual is certainly different from 

 all otliers we have seen, but we do not believe that it is anything else but an 

 abnormal specimen ; anyhow, a single example from a particular place is certainly 

 not sniKcient to base a geographical race upon if the individuals from the 

 surrounding coiuitries are of the ordinary tyj)e. 



The S oi' ore/ lata copulates in confinement comparatively easily with the ? of 

 Amorpli't popnli. The offsjiring of such a union staud in structure, sh.ipe, and 

 colour, intermediate between the parent species. The tliorn at the end of the 

 foretibia is short, mostly concealed under the scaling, the jienis-siieath resembles 

 that of fiopHli, the teeth of the duct are cither partly or all rejilaced by fine 

 bristles ; tln' harpe agrees better with that of orellata, lieing, however, longer iind 

 slenderer. 



Autlientic offspring of tiie reverse union are now also known, Staudfuss's 

 experiments having at last been successful in so far as he reared two ? ? of tliis 

 hybrid. The statement apjieariug in various books that the hybrid populi x ocellata 

 is identical with populi has, as a matter of course, no foundation. The specimens
