Fig. 1. Holotype of Hadena hausta Grote. Actual length of primary is 10.6 mm.

semicana agree with O. hausta on this character. The posterior end 
of the reniform touches the postmedian line on all four O. hausta 
before me, but this is the case on only five of 35 O. exhausta 
examined. 
Oligia hausta is apparently rare in collections. The fact that 
Forbes did not regard it as distinct suggests that he was not familiar 
with it. Besides the type, which is dated 1 1 July 1882, there are two 
other specimens in the MCZ collection from Peggy’s Cove and 
Digby, Halifax Co., Nova Scotia, 11 and 14 July 1953, leg. D. C.

wetlands. He reports taking another on 22-24 June. These will be
