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



P. fraternus 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 fraternus the scutellum is likewise pale, thereby referring the 

 specimen to ohscurus; specimens having a black scutellum rarely 

 have the pronotum pale as described for fratermis. For the 

 present, the writer designates as fraternus 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, fraternus Uhler 

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

 vertex .38 mm. ; black, slightly paler at base of vertex. Rostrum, 

 length 1.83 mm., yellowish, basal segment blackish except apically. 



Antennae: Segment i, length .38mm., black, narrowly pale at

 pale fuscous.
