locality. Georgia. This is evidently different from any species 

 I have seen. 



Andrena nivalis, Smith, 1853. 



? . " Tubercle / \ ; antennal joint 3 longer than 4 + 5 ; area rugose at 

 base; abdomen distinctly punctured, but on an aciculated surface." 

 Type locality, Hudson's Bay. This is very near to A. semirufa, 

 CklL, from New Mexico ; possibly it is the same species. 

 Andrena hilaris, Smith, 1853. 



$ . " Tubercle of labrum wide, truncate, below its centre a projecting 

 pencil of golden hairs ; clypeus coarsely punctured, with a smooth 

 shining carina down its middle ; metathoracic area finely rugulose, 

 with some coarse short longitudinal strigpe at its base ; abdomen 

 distinctly punctured, its surface also microscopically (hardly 

 visibly) rugulose ; wings very yellow." Type locality, Georgia. 

 Evidently distinct from anything I have before me. 

 Andrena vicina, Smith, 1853. 



°_ . Length "about 14 mill.; tubercle wide, truncate; clypeus with wide 

 unpunctured central elevation; area dull rugulose; abdomen finely 

 rugulose all over, and distinctly but shallowly punctured." Smith 

 gives the length as only 5 lines, and says the species closely 

 resembles A. nitida. I hardly know what to make of this ; the 

 species referred to vicina in American collections has the tubercle 

 low and rounded, by no means truncate ; also, it does not have the 

 very shiny, oval abdomen of nitida, which species, it may be 

 remarked, has the tubercle concavely truncate. A. vicina is said 

 to be from the United States and Nova Scotia. 

 Andrena placida, Smith, 1853. 



9 . " Tubercle very narrowly truncated ; area rather coarsely rugulose, 

 but not margined, I think ; abdomen rugulose, a few sparse punc- 

 tures ; length about 12 mill., much smaller and narrower insect 

 than vicina — looks like a J>arviceJ>s." From "U. S." Smith gives 

 the size the same as that of vicina, but this must be a mistake. 

 A. placida seems to come close to A. Macgillivrayi. 

 Andrena fastuosa, Smith, 1879. 



$ . " Tubercle / w \ , difficult to say if actually emarginate ; area and 

 abdomen as $ ." 



g. "Tubercle emarginate; huge stipites ! area rugose, unmargined ; 

 abdomen closely punctured." From Orizaba, Mexico. Andrena
