Long Island, N. Y., based on some "ferrugino-testaceous" 

 females which were taken in company with a reddish-colored 

 ant (Camponotus castaneus Latr.) which the bug resembles very 

 closely. Uhler stated (loc. cit.) that "immature forms of 

 obliqiius are chestnut-brown, with the white markings less dis- 

 tinct."
