No. 34-] HEMIPTERA OF CONNECTICUT I MIRIDAE. 



5°3 



of pronotum, scutellum, clavus, inner half of corium, and mem- 

 brane, fuscous; genital claspers (fig. 68), distinctive of the 

 species. 



Female: Length 5.6 mm., width 2.1 mm. ; more robust than the 

 male but very similar in coloration. 



When described the food plant of this species was unknown, but 

 in the short interval since that time, the insect has appeared as a 

 serious pest on the cultivated Phlox, in Arkansas, Minnesota, and 

 West Virginia. It may very well be called the ''phlox plant bug."
