deposited in the Cape Cod Museum of Natural History, in Brewster. 
All specimens seen are males. 
Mark Mello has a specimen of one of the two taxa that commonly 
pass for O. semieana in New England from the Wellfleet site. It 
differs from Hampson’s figure in that there is no prominent 
antemedian line and the entire forewing inside the postmedian line is 
rather uniform dark gray, except for the paler reniform. 
The differences in maculation of the forewing between O. hausta 
and the other species in the exhausta-semieana section of Oligia 
seem sufficient to justify treating O. hausta as a valid species as was 
done by Franclemont and Todd. This species seems to combine 
characters of the immediate semieana group and the distinctive O. 
exhausta.
