“This I suspect is the ♂ of integra; area similarly strigose, and abdomen also corresponds; tubercle matches also!”

Robertson thought this might be A. platyparia: 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.

“♂ 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.
