1870. Butl., Ent. Monthl. Mag. vii. 9G: indicates Morpheus (Ster- 

 opes) as type, but erroneously, because Morpheus was 

 taken by Dumeril as the type of Heteropterus in 1823. 

 By a similar error, 

 1872. Scudd., Syst. Ilev. 54: indicates Morpheus (Sterojies) as the 

 type. 

 Palaemon or Sylvius cannot be taken as the type, as would follow 

 from Stepliens's action in 1800, because Palaimon must be taken for 

 Pam{)liila (q. v. J : Metis may tlierefore be selected. See also Erynnis. 



309. Cycnus. 



181 G. Ilubn., Verz. 81 : Chiton, Phaleros (Agis, Phaleros), Linus 

 (iEtolus). 

 Phaleros may be taken as the type. 



310. Cyllo. 



1832. Boisd., Voy. Astrol. 140: amabilis, Constantia, Leda. 



1844. Doubl., List Br. Mus. 120: employs it for the two latter 



species and others. 

 1851. Westw., Gen. Diurn. Lep. 300 : designates Leda (Leda, Bank- 



sia) as type. 



311. Cyllogknes. 

 18G8. Butl., Ent. Monthl. Mag. iv. 194: Suradeva. Sole species 

 and designated tyj^e. 



312. Cyllonium.* (Fossil.) 

 1854. Westw., Quart. Journ. Geol. Soc. Lond. 395-6 : Boisduval- 

 iunum, Hewitsonianum. 



The latter is not a butterfly, and it is exceedingly doubtful if the 

 former can be so considered. The genus is uncharacterized, but the 

 species are figured ; they are, however, so fragmentary that it would 

 be impossible to trace any generic characters from them. 



313. Cyllopsis. 



18G9. Feld., Verh. zool.-bot. Gesellsch. Wien. xix. 474: Hede- 

 manni. Sole species, and therefore type. 



314. Cym^enes. 



1872. Scudd., Syst. Rev. Gl : tripuncta, malitiosa. Tripuncta speci- 

 fied as type. 



315. Cymatoguamjia. 



1849. Doubl., Gen. Diurn. Lcp. pi. 49 : Echerus. Sole species, 



and therefore type. 



1850. lb., in Westw. Gen. Diurn. Lep. 315: the same.
