4. PIPIZA Fallen. 



1. Pipiza femoralis Loew. 



One male from Roca, Nebraska, May, 1906 (P. R. Jones). It 

 agrees completely with Loew's description except that the eyes and 

 face are more pilose. 



Formerly recorded from Illinois, Missouri, Pennsylvania, and 

 Quebec. 



2. Pipiza f estiva Meigen. Y" 



Two females from Roca, Nebraska, May, 1906, on Fragaria vir- 

 giniana (P. R. Jones). 



Length 8 mm. Front and face long white pilose, black pilose fat the base of 

 antennae and ocelli. Antennae brown, darker on apical part of third joint which is 

 broad, and as Loew says trapezoidal. Abdomen shining bronze-black, second seg- 

 ment with two nearly quadrate sulphur-yellow spots. Legs yellow with black femora, 

 tibiae brown in the middle. Wings hyaline at the base, smoky on the outer half so 

 that they appear to have a large brown spot below the stigma in the center of the 

 wing. 



This is the first definite record of this species being taken in the 

 United States. Williston says in his monograph: " I give the de- 

 scription of this species, although it is not known for certain that it 

 occurs in this country, it being given in Osten Sacken's catalogue, 

 with the remark, 'or a species allied to it,' as occurring in Canada."
