Occurrence of a European Anthomyiid in Illinois (Diptera). 



On August 24, 1917, in company with T. H. Prison, I captured 

 on the shore of Lake Michigan a large series of a very pale colored 

 anthomyiid fly that structurally very closely resembles the common 

 cilicrura Zetterstedt. On making a careful examination of the species 

 I identified it as Phorbia albula Zetterstedt, a species recorded as 

 occurring on sandy soils in Europe. The species was found on the 

 bare sand along the shore of Lake Michigan, north of Waukegan. and 

 was very common. Owing to its very pale color it was very difficult 

 to see the insect on the dry sand, but large numbers could be taken 

 by sweeping with the net very close to the ground. Along with this 

 species were two others, Phyllogastcr littoralis Malloch and Tetra- 

 mcrinx brcvicornis Malloch, both of which were much scarcer than 

 albula. J. R. MALLOCH, Urbana, Illinois.
