This species resembles C. leguminicola Melander, from Oregon, but 

 the entirely black scutellum, darker and the small apical clouding on 

 the wings separate it from that species. 



Pseudotephritis vau Say, var. approximata Banks. 



P. appoximata Banks, Proc. Ent. Soc. Wash., 1914, vol. 14, p. 138, corrected 

 to approximata in the index, p. 185. 



P. metzi Johnson, Psyche, 19-15, vol. 22, p. 49. 



In the types of P. approximata and P. metzi the spots on the cross- 

 veins are widely separated and the sub-basal clouding is interrupted 

 at the fourth vein. I now have before me two other specimens. One 

 from the Delaware Water Gap, Pennsylvania, collected by Mrs. Annie 

 T. Slosson, has the spots on the cross-veins separated by only one- 

 third the distance of that in the type of metzi; the second, from 

 Brookline, Massachusetts, September, 1920, collected by C. E. 

 White, Jr., has the spot on the cross-vein very narrowly separated and 

 of a yellowish color as in the typical P. vau, and the sub-basal clouding 

 is not interrupted at the fourth vein. The two specimens show very 

 clearly that this is undoubtedly only a variation of Say's species. 



Pseudotephritis vau Say, var. conjuncta, var. nov. 



Another striking variety of this species was collected by the writer 

 on an old log near the Beaver Dam Pond, Bar Harbor, Maine, August 

 10, 1920. In this the pre-apical costal spot is connected with the 

 spots in the posterior cross-vein, forming a quite regular band of even 

 width, and widely separated from the marking on the anterior cross- 

 vein. The clouding is not interrupted at the fourth vein. Length 

 6.5 mm.
