PSEUDOTEPHRITIS (PSEUDOTEPHRITIS) APPROXIMATA (Banks) 



Pseudotephritis approximata Banks, Proc. Ent. Soc. Washington, vol. IG, p, 

 138, 1914. 



Originally described as a valid species, this form has been reduced 

 to a variety by Johnson in several recent papers, including his list 

 of New England Diptera, and Avith it is placed metzi Johnson as a 

 synonym. I accept approxiviata as distinct from vau^ and also from 

 nietzi^ though as indicated in the introductory paragraphs it is 

 somewhat doubtful if this is the case. 



Originally described from Virginia, I have seen it from Ames, 

 Iowa, Pennsylvania, Lafayette, Ind., and Washington, D. C. It 

 lias also been recorded from Massachusetts and New York. 



PSEUDOTEPHRITIS (PSEUDOTEPHRITIS) METZI Johnson 



Pseudotephritis metzi Johnson, Psyche, vol. 22, p. 49, 1915. 



Originally described as a valid species from Massachusetts, I 

 have seen it from White Mountains and Springfield, Mass., St. 

 Paul, Minn., and Bilby, Alberta, Canada (Owen Bryant). 



PSEUDOTEPHRITIS (PSEUDOTEPHRITIS) CONJUNCTA Johnson 



Pseudotephritis conjuncta Johnson, Occ. Pap. Boston Soc. Nat. Hist., vol. 5, 

 p. 15, 1915. 



This species is very close to approxiTnata if not actually a variety 

 of it, the only distinctions between it and metzi and approodmata 

 that I can find being those cited in the foregoing key to the species. 

 Some specimens of inetzi in the National Museum and one of ap- 

 proximata have the fascia over the outer cross vein almost as 

 complete as in the present form. 



Originally described from Maine, and there is but one specimen 

 identified by Dr. J. M. Aldrich as this in the National Museum, 

 and that from the same State. 



PSEUDOTEPHRITIS (PSEUDOTEPHRITIS) CORTICALIS (Loew) 



Stictocephala corticalis Loew, Monographs of the Diptera of North America, 

 pt. 3, Smitlisoniau Misc. Coll. 256, p. 136, 1872. 



This species is readily distinguished from its congeners by the 

 characters cited in the foregoing key to the species. 



Originally described from New York State. Subsequently re- 

 corded from Connecticut. I have seen a series in the National 

 Museum reared from larvae found under the bark of a tuliptree, 

 Dead Kun, Va., April, 1913 (K. C. Shannon), and single specimens 

 taken at Washington, D. C, May 13, 1911 (W. L. McAtee), and 

 Bilby, Alberta, Canada, May 13, 1925 (Owen Bryant).
