Habitat. — Northern and Eastern States; Canada and northward;

The type of perconflua is like the type of jucunda, and Mr. Grote's name 

 sinks. Perconffna is undoubtedly the species Mr. Grote has written 

 of as conflua; but the specimen in the British JMuseum, labeled vonjiua 

 by Mr. Grote, is ruhifera. The type of esurialis, also in the Museum, 

 is without doubt the same species, differing only in tliat the orbicular 

 is imperfectly closed superiorly, and the cell between the ordinary 

 spots more pronunent than usual. The specimen is from Washington, 

 and is perhaps a good geographical race.
