Phorbia R. D., Myod. 559, is also omitted. One species, P. floccosa, 

 has also been found by Dr. Lintner mining beet leaves (1. c 

 207). The two common species, formerly known as Anth. ce- 

 parum and .4. radicum var. calopteni, have been referred to the 

 genus Phorbia. The determinations are by Dr. Meade. Phorbia 

 is nearer to Chorfophila than is the preceding genus Pegomyia. 

 It agrees with Chortopkila in the legs being black, and is thus 

 separated from Pegomyia. It is. separated from Chortojjhila by 

 the abdomen of the S being narrow, or oblong and depressed, 

 while in that genus it is subcylindrical.
