Pegomya transgressa (Zetterstedt 1846)

Pegomyia corrupta Huckett
Pegomyia corrupta Huckett, Trans. Amer. Ent, Sue, i.xv, p. 13, 1939.
The species corrupta has the habitus of albimargo (Pandelle), under which name it was first recorded by Malloch 84 as occurring in North America. 1 have reexamined the specimens which formed tinbasis for this record and believe them to be distinct from albimargo on account of the absence of mesonotal stripings and scutellar marks that characterize the albiwargo-subgvoup. The male specimens of corrupta that 1 have seen exhibit a certain degree of variability in abdominal and femoral coloration. In one of the paratypes the abdomen is partly yellowish and the hind femora are yellowish proximad. whereas in the remaining specimens the femora are entirely blackish, resembling those of flavifrons (Walker). The processes of corrupta also resemble those of flavifrons in structure and bristling, but they are not so widely separated from one another as in that species. I have seen another specimen of corrupta taken by J . S. 1 line at Naknek Lake, Savonoski, Alaska.
