32 Trans. Acad, of St. Louis 



were on buck-brush blossoms and sweet-clover in July 

 and August. 



Halictus tegularis Robt. [J. C. Crawford]. A female 

 was seen going into its burrow in the sand at Lake View, 

 Kansas, July 26, 1916. 



Halictus zephyrus Sm. [J. C. Crawford] . A colony of 

 these bees was seen at Creve Coeur Lake on June 13, 

 1918. The entrance of each burrow was blocked by the 

 head of the male occupant. This great number of bright 

 eyes peering out their dark doorways was quaintly sug- 

 gestive of a neighborhood of curious gossips. The 

 females were coming in from time to time laden with 

 pollen. The orifices of the tunnels were small enough to 

 admit no intruder when the head of the male closed the 

 opening, but beyond that point the tunnels were much 

 wider. They went into the bank horizontally for several 

 inches. 



Augochlora similis Robt. [J. C. Crawford]. A cluster 

 of seven cells (See Plate VI, fig. 6) was taken from under 

 the bark of a log at Wickes on August 10, 1917. These 

 were made of coarsely chewed bits of wood, and held 

 together by some unknown substance. Adults of this 

 species emerged from these later. This species also 

 nests earlier, for on May 10, 1915 at Meramec Highlands, 

 a similar collection of cells was taken from a like situa- 

 tion; the occupants were in the larval stage and were 

 feeding on the pellets of bee-bread provided for them. 



Augochlora confusa Robt. [J. C. Crawford]. A female 

 heavily laden with pollen had fallen prey to a spider, 

 Fhidippus audax Htz. [J. H. Emerton]. The pair was 

 found on the window-sill at Wickes, July 18, 1917. 



Augochlora pura Say. [S. A. Rohwer]. This bee, a 

 male, was feeding on the wild flowers at Cliff Cave, April 

 21, 1920. 



Augochlora prunus Say. [S. A. Rohwer]. Dozens of 

 these bees were seen during the day, April 23, 1920, when 

 the old bark was peeled from fallen trees. They evi-
