New distributional records are given for two Palearctic hemipterans established on Scotch broom, Cytisus scoparius (Fabaceae), in the Pacific Northwest. Additional records for the centrotine membracid Gargara genistae (F) include British Columbia (Vancouver Island), Oregon (seven sites in five counties), and Washington (eight sites in six counties). For the tingid Dictyonota fuliginosa Costa, we give new records from British Columbia (lower mainland and Vancouver Island) and Oregon (five counties) subsequent to the recent (2008) updating of its North American distribution.
