Notes. A single male specimen from the northern LP identified by Roy Snelling and tentatively confirmed by JG is deposited at MSUC. A female record from PWRC remains uncertain due to the difficulty in distinguishing this sex from H . mesillae but is plausible given the boreal habitat present there. Although rudbeckiae is abundant in the western United States , it has only rarely been recorded from states east of the Rocky Mountains, where expected only from near the Canadian border, but identification difficulties may obscure its true status. A Wisconsin record ( Mitchell, 1960 ) was not accepted by Wolf & Ascher (2009) but should be reevaluated as it may prove valid. Mitchell’s records from Connecticut (also reported by Hurd, 1979 ) are less likely to be correct, and we consider a possible New Jersey record ( Hurd, 1979 ) to be implausible given that confirmed records in eastern North America are from boreal sites.
