surely belongs neither to C. cequabilis nor to the species from Hud- 

 son's Bay. The large dimensions of Drury's figure, which prevented 

 De Selys from recognizing it as C. maculata, are equalled by some 

 females from Texas and Kentucky; the length of the wings only 36 

 millim., instead of 37 millim. in Drury's figure. Drury's coloration 

 and description makes it doubtless that his species is C. maculata. 



The males from Georgia, described as C. virginica in Selys' 

 Monogr., belong probably to C. cequabilis. The female from Hud- 

 son's Bay, C. virginica Selys' Monogr., belongs to C. hudsonica. In 

 the Proc. Bost. Soc. Nat. Hist., XV, 274, I considered both species 

 to be identical, but I had not seen at that time females of C. ozquabi- 

 lis, and only a female and two imperfect young males of C. hud- 

 sonica.

 erroneous.
