No. 34-] HEMIPTERA OF CONNECTICUT I MIRIDAE. 439 



P. fratemus Uhler. 



Uhler, Hemip. Colo., 51, 1895. 



Of all the material examined, the writer has found not more 

 than three specimens which fit the original description as regards 

 color of scutellum and pronotum. Where the pronotum agrees 

 with f rat emus the scutellum is likewise pale, thereby referring the 

 specimen to obscurus; specimens having a black scutellum rarely 

 have the pronotum pale as described for fratemus. For the 

 present, the writer designates as fratemus those specimens having 

 a black scutellum even though the pronotum may likewise be black, 

 other characters as indicated in the key. 



Judging by the large amount of material thus far examined, 

 from Colorado as well as the eastern states, fratemus Uhler 

 appears to be nothing more than a variety of obscurus Uhler.
