Milwaukee, Wis., 5 ^ , 20 9 specimens. This bee flies from 



August 25th to September 26th. The size of the head of the 



male is very remarkable. In this respect the male surpasses 



the male of any other species of Andrena sens. lat. known from 



this localitj-.

White vs. Black Pins. — My insect room is very hot and dry, during 

 the summer months. The high temperature has so hastened greasing of 

 the specimens, and the formation of "green oxide" on the white pins, 

 that I have been obliged to discard them, and use the black japanned 

 steel pins. These have the advantage of being sharp and stiff, though 

 they are not very smooth ; however they work well in this very dry room. 

 But while at Brownsville, Texas, during last April and May, the black 

 pins rusted badly. 1 am sure a long stay in such a damp locality would 

 ruin them. — Charles Dury.
