The specific name proposed alludes to the length of the 

 inferior appendage of the male which acts as an opposable 

 organ (hence polle.v) in grasping the female. 



The figures illustrating the appendages of the abdomen and 

 the genitalia have been drawn from under the compound mi- 

 croscope with the camera lucida. The wings were photo- 

 graphed to as large a scale as our camera permitted, a blue 

 print made from the negative, the veins inked with water- 

 proof black ink, the blue background washed to white with 

 ammonia water and "copy" thus obtained for the engraver. 



Having very little literature on the Odonata accessible to

 as in longipollex, are without any promiences but are con- 

 spicuously dilated apically as opposed to the subuniform thick- 

 ness of the appendages throughout in longipollex; and the 

 inferior appendage is shorter than the superiors, not greatly 

 exceeding them as is the case in longipollex. No changes 

 have been made in Dr. Calvert's manuscript. E. B. W. 



The Bees of Virginia Prosopis, Sphecodes, Osmia. 



BY JOHN H. LOVELL, Waldoboro, Maine. 

 The bees of the southern states are so imperfectly known 

 that collections from any part of this region possess more than 

 usual interest. Some months ago I received from Dr. Nathan 

 Banks for determination a collection of bees largely from Vir- 

 ginia belonging to the genera, Osmia, Sphecodes and Pros- 

 opis. Only a few species of Osmia and Prosopis have been re- 

 corded from this state, while the genus Sphecodes is wholly 

 unknown from this area. A list of the species is as follows :
