Agromyza ahnormalis Malloch. 

 This species differs from obscuritarsis Rondani in being 

 more robust, darker in color throughout, and particularly 

 in that the frons and halteres, and in neuration, the last section 

 of fifth vein in obscuritarsis being about one and one-half 

 times as long as penultimate section. Both species have 4 

 pairs of dorso-centrals. 



Agromyza kincaidi Malloch. 



On comparison of the type of this species with specimens 

 submitted from Budapest museum as nigripes, I find that the 

 European form has over all a more glossy black color, the 

 frons is much narrower, being barely wider than width of 

 either eye, and narrowed anteriorly, the arista is almost bare, 

 the squamae are darker, with brown fringes, and the last 

 section of fifth vein is almost as long as the penultimate section. 



An example from Hampton, N. H. (S. A. Shaw) agrees in 

 almost every particular with those from Europe so that this 

 species may be added to the American list and the name 

 changed to subnigripes n. nom. for the reasons stated in this 

 paper. 



Agromyza pruinosa Coquillett. 

 This species has been reared from larvae mining under 

 bark on birch trees by C. T. Green of the Division of Forest 

 Insects, at Falls Church, Va. I have examined two males 

 which agree in every particular with the type, except in being 

 rather larger. 



Agromyza ccerulea Malloch. 

 I have examined a series of 8 specimens reared from Ipomoea 

 sinuata and 5 ' from Ipomoea lacunosa, at Victoria, Texas, 

 in September, 1907, and 7 from same locality August, 1907, 

 labelled Ipomoea, by J. D. Mitchell. They agree with the 

 Mexican specimen in all particulars. 



Agromyza texana Malloch. 

 Two pairs taken in copula at Kerrville, Texas, June 19, 

 1907 (F. C. Pratt).
