Andrena fragilis, Smith, 1853. 



" This I suspect is the $ of Integra ; area similarly strigose, and 

 abdomen also corresponds ; tubercle matches also !" 



Robertson thought this might be A. plat y par ia : but, he said, the 

 description applied even better to salicis, and nearly as well 

 to mandibularis. It cannot well be salicis, as that has the 

 abdomen impunctate; if it is the $ of Integra, it cannot well 

 be mandibularis ; it may perhaps be platyparia. 

 Andrena frigida, Smith, 1853. 



"(Very near apicata, but hairs of thorax much darker) ? —lapponica; 

 antennae with very long third joint ; tubercle n ; area granulated ; 

 abdomen in style of apicata." 



Type locality, Nova Scotia. I do not know any similar species. 

 Andrena fimbriata, Smith, 1S53 (Americana, D. T.). 



" o* abdomen rugulose and punctured, clothed with long adpressed 

 hairs ; tubercle slightly emarginate (?); area dull granulose ; $ 

 ditto. (Very near fuscipes, perhaps identical with it.)" This agrees 

 with what I had already identified from Smith's description. It 

 seems to argree with the description of A. simillima, Sm., even 

 better than with that of fuscipes, but I doubt its actual identity 

 with either. 



Andrena hirticeps, Smith, 1853. 

 $ . "Tubercle pointed apparently, hard to see under thick bush of hair 

 on clypeus ; area obliquely rugose at base only, no raised margin ; 

 abdomen tessellate, practically impunctate ; apical ventral valve 

 somewhat bilobed ; antennae with article 3 = 4 + 5 about, all 

 joints pretty long. Has a good deal the aspect of gwynana." 

 This was considered the $ of A. vicina, but Robertson (1900) has 

 come to regard it as a valid species. He further adds : " But for 

 the description of the o* > I would say that A. erraus is the same as 

 A. hirticeps." I have an Illinois '■'■hirticeps," $ , from Mr. Robert- 

 son, and the abdomen is distinctly punctate at the bases of the 

 hairs, while the third antennal joint is barely longer than the fifth, 

 the fourth being a little shorter than either. The apical ventral
