Guenee's type is in the British Museum. Mr. Grote, 111. Essay, 45, 

 refers P. mobilis Wlk., C. B. M., Het., x, i'77, as a synonym to this 

 species, but I think incorrectly so. Walker's type is from the West 

 Indies and differs quite evidently from our specimens. It may prove 

 a geographical race eventually, but the material is not yet at hand to 

 decide this positively. The type of en it-n is also in the British Museum, 

 and without a large amount of material certainly looks like a distinct 

 species.

HABITAT. New York in June and August; Massachusetts in July; 

 southward to Florida and Texas; Colorado; District of Columbia in 

 August. 



The types of all the names are in the British Museum, and all refer 

 to the same species. Mr. G rote's suggestion that Walker's name be 

 abandoned because already used in an allied genus is settled by Gueuee's 

 taking it. Vecors had not been identified heretofore.
