GENERIC NAMES OF BUTTERFLIES 117 



CITHAERIAS Hiibner, [1819], Verz. bekannt. Schmett. (4) : 53. Type-species by selection by 

 Scudder (1875, Proc. amer. Acad. Arts Sci., Boston 10 : 143) : Papilio andromeda Fabri- 

 cius, 1775, Syst. Ent. : 467. 



CITHAERIS Druce, 1876, Proc. zool. Soc. Lond. 1876 : 211 (an Incorrect Subsequent Spelling 

 of Cithaerias Hiibner, [1819]). 



CITRINOPHILA Kirby, 1887, Ann. Mag. nat. Hist. (5) 19 : 367. Type-species by original 

 designation : Citrinophila marginalis Kirby, 1887, ibid. (5) 19 : 368. 



Aurivillius ([1819], in Seitz, Grossschmett. Erde 13 : 326) treated Citrinophila marginalis as 

 the male of Citrinophila similis Kirby and called the species so recognized by the name 

 similis. Stempffer however {in lilt.) treats these nominal species as representing separate 

 taxa at the species-level. 

 CLEIS Guerin, [1838], in Duperry, Hist. nat. Crust. Arachn. Ins. Coy. " Coquille " (22) : 

 pi. Ins. 18. Type-species by monotypy : Cleis posticalis, 1831, ibid. (22) : pi. Ins. 18. 



In the text of his work (: 272) Guerin quoted a note published by Boisduval in the Insectes 

 section of the Voy. " Astrolabe " after the appearance of the plate on which Guerin had 

 figured his new species Cleis posticalis, in which Boisduval stated that the taxon represented 

 by this nominal species was " certainement une nocturne ". Boisduval added that he had 

 himself described the species concerned under the name Damias melaxanthe Boisduval, 

 [1832] (in d'Urville, Voy. "Astrolabe ", Ent. 1 (Lep. (1) : 260). Later in the Hist. nat. 

 ( : 286) Guerin, commenting on Boisduval's note, stated that he was unable to accept the view 

 there put forward. 



Boisduval was however perfectly right. Cleis is not a genus of butterflies. 



CLEODIS Boisduval, 1870, Consid. Lipid. Guatemala : 30. Type-species by subsequent 

 selection by Hemming (1964, Annot. lep. 1 (4) : 117) : Callithomia alexirrhoe Bates, 1862, 

 Trans, linn. Soc. Lond. 23 (3) : 522. 



Boisduval established Cleodis as a subgenus of Xanthocleis.a. genus then also newly establish- 

 ed. He gave a diagnosis lor this genus, which, though brief and vague according to modern 

 standards, is sufficient to validate this name. He did nut however cite any nominal species as 

 belonging to Cleodis. the name was either ignored by later authors or was incorrectly 

 treated as having been published as a nomen nudum, until in i960 I selected Callithomia 

 alexirrhoe Bates to be type-species of this taxon. 



Before making this type-selection, I consulted Dr. Richard Fox, the well-known authority 

 on the Ithomiids, who expressed the opinion that of the species likely to have been known to 

 Boisduval and in his mind when he published the name Cleodis the species which best fitted 

 Boisduval's diagnosis was Tthomia napho Felder (C.) & Felder (R.), [1865], a species now 

 placed in the genus Callithomia Bates, 1862. Mr. N. D. Riley, whom I also consulted, agreed 

 that the characters cited by Boisduval agree best with those exhibited by the genus Calli- 

 thomia but considered that in the case of a long-neglected name such as Cleodis the best course 

 would be to select as the type-species a nominal species which would make the generic name in 

 question a junior objective synonym of a name of older date and not merely a junior subjective 

 synonym, such as Cleodis would be, if Tthomia napho were to be selected to be the type-species. 

 I agree with the view expressed by Mr. Riley in this matter, and have accordingly selected as 

 the type-species the nominal species Callithomia alexirrhoe Bates to be the type-species of 

 Cleodis. As that species is currently treated as being congeneric with Ithomia napho, its 

 selection as type-species is in harmony with the taxonomic view expressed by Dr. Fox as to 

 the general position best assigned to Cleodis, while the fact that it is also the type-species 

 of Callithomia Bates secures the desired end of rendering the name Cleodis invalid, by making 

 it a junior objective synonym of the older-established name Callithomia Bates. 



CLEOSIRIS Boisduval, [1836], (Roret's Suite a Buffon), Hist. nat. Ins., Consid. gen. Lepid. 

 1 : explic. pi. 23 [ = pl. 7C]. Type-species by monotypy : Tetragonus catamitus Geyer, 

 [1832], in Hiibner, Zutr. z. Sammll exol. Schmett. 4 : 17, pi. [113], figs 653, 654. 



The name Cleosiris was published by Boisduval on the legend to a plate on which all the
