Notes on Type Material: The type material of C. inaequalis from Indiana is presumed lost, so a neotype ♀ was selected by Stephen (1954 - see above), though the Smithsonian (i.e., USNM) type database currently has a ♂‚ specimen (USNM no . 534564 - the specimen selected by Stephen (1954) as the neoallotype) as the neotype. In addition, the date on the label of this ♂‚ is incorrectly interpreted; Stephen (1954) indicates 3 May 1902 (and 19 May 1902 for the ♀), versus 6 March 1902 in the USNM database.

Although Stephen (1954) refers to a type specimen of C. propinqua, Cresson (1868) indicates multiple type localities [Mass., Pa., Va., Ill.], none of which were designated as a lectotype. However, the Entomology Type Collection at ANSP indicates a ♀ specimen from Massachusetts [no. 2146]. 

Although Stephen (1954) refers to a type specimen of C. inaequalis ferrugineus, Swenk (1908) indicates that 31 syntypes exist, none of which were designated as a lectotype.
