$, Newark, May. 9? Prospertown, June i. Not included in 

 the table ; the $ has the clypeus yellow with two black spots ; the 9 

 is known by the small size, clypeus (black) punctured only at sides, 

 the middle smooth and shining, process of labrum broad, abdomen 

 tessellate and practically impunctate, wings yellowish, nervures and 

 stigma honey -color, etc.

 men of hippotes received from Robertson. The four hind tarsi, and 

 the two hind tibiae of the 9 are red. 



Andrena placida Smith.

 certainly correct. Marked ''A. viola,' ^ but not congeneric with 

 lomelissa violce, Rob.

A 9 with no data; marked ^^ salicis,'' which it is not.
