Hab. Briar Creek, Georgia, April 18 ; Bee Spring, Kentucky, 

 June. 



Of this rare species only three specimens are known ; the male 

 (C. angustipennis) from Abbot, in the British Museum, figured by 

 Abbot; an immature and imperfect female specimen (C. elegans)) 

 locality not known, and an adult female from Kentucky in my collec- 

 tion. The difference quoted in Selys' Monogr., p. 21, in the direction 

 of the principal sector, was found, after a repeated examination of 

 the male type in the British Museum, not to exist.

 Hab. Philadelphia, Pennsylvania. 



The locality Massachusetts in my Synopsis, p. 57, was given by Mr. 

 Uhler. I have seen two females, Waltham, July 21, but each of 

 them possesses a very small white pterostigma; one male, partly 

 broken, from the same locality ; probably they belong to this species.

Hab. Norway, Maine; Brookline, Tyngsboro, Mass.; probably 

 Rock Island, III.; probably Georgia; the males in the British Museum 

 quoted as C. virginica in Selys 1 Monogr., 31. 



With the C. virginica Selys, Monogr., 29, 6, Syn., 11, 6, Walk. 

 Cat., 592, 6, Hag. Syn., 58, 5, probably are mixed together three 

 different species, viz. : C. maculata, C. cequabilis, and a new one 

 from Hudson's Bay.
