Type-species designation:

Hemming (1967) stated:-

Westwood placed in this genus (which he did not characterize) two new nominal species which he called C. boidusvalianum and C. hewitsonianum. He gave no description for either of these fossils but provided figures of each, the first on plate 17 (fig. 17), the second on plate 18 (fig. 27).

Scudder in 1875 (Proc. amer. Acad. arts Sci., Boston 10 : 151) expressed the view that it was "exceedingly doubtful" whether C. boisduvalianum was a butterfly and that C. hewitsonianum was certainly not one ; he added that these fossils were "so fragmentary that it would be impossible to trace any generic characters for them". In another paper published later in the same year (Mem. Amer. Ass. Adv. Sci. 1 : 89) Scudder set out in detail the grounds on which he had by this time come to the conclusion that neither of these species was a butterfly.
