2. P. pygmaea Cr., 1869. 



A small species ; length 4 mm. My first specimens were 

 taken this season on the garden blackberry June 19th, and my 

 last on the goldenrod August 22nd ; this bee was also taken on 

 the wild rose and Aralia hispida. Nine $ and eight $ speci- 

 mens taken at Waldoboro, Maine, and seven $ and four $ 

 specimens collected at Elkhart, Indiana. 



9. — Face marks bow shaped, yellow (in one specimen nearly dark) ; 

 clypeus and supraclypeal piece dark, finely and irregularly striate ; in one 

 specimen there is a small dot on clypeus. Collar dark, two yellow spots 

 on tubercles, sometimes with a minute dark dot in the center ; tegulae 

 either with or without a yellow spot. First segment of abdomen smooth 

 and shining, no apical fringe of pubescence on segments. 



(^\ — Base of all the tibiae, tubercles, clypeus, supraclypeal piece and 

 sides of face pale yellow ; upward extensions of lateral face marks diverg- 

 ing from the orbit, and slightly enlarged and rounded at apex. Supra- 

 clypeal mark longer than broad. Yellow line on scape in front, flagellum 

 testaceous beneath. 



In Illinois females frequently have a spot on clypeus, and 

 usually a spot on tegulae ; but the males are frequently without 

 spots on tegulae. 



3. P. saoicnlae Rob., 1896. 



$. — .More slender than P. pygmcea. A narrow, rather short yellow 

 stripe on each side of the face, not filling the space between the clypeus 

 and orbit. A yellow spot on each of the hind tibiae ; collar, tubercles and 

 tegulae dark. Head and thorax finely punctate ; abdomen impunctate, 

 shining ; apical segments minutely pubescent. 



My specimens were taken July 1 5-1 6th on Aralia hispida. 

 Waldoboro, Maine. 3 9 specimens ; Elkhart, Indians, 2 % 

 specimens. 



4. P. modesta Say, 1897. 



9 . — Face marks triangular, two yellow spots on collar and tubercles, 

 and base of all the tibiae yellow. Flagellum testaceous beneath. No yel- 

 low spots on tegulae or edge of wing-base. Head and thorax closely 

 punctured ; first abdominal segment smooth and shining, with lateral 

 apical fringe of white pubescence. Wings dusky hyaline. 



Elkhart, Indiana, 4 9 specimens. Robertson regards it as 

 probable that Say's description was based on specimens taken 

 in Indiana. 



The females of this species in Illinois do not differ from this
