GENERIC NAMES OF BUTTERFLIES 417 



STAEMASTIS Mabille, 1903, in Wytsman's Gen. Ins. 17 (A) : 70 (an Incorrect Original 

 Spelling of Haemactis Mabille, 1903). 



STALACHTIS Hiibner, 18 18, Zutr. z. Samml. exot. Schmett. 1 : 9. Type-species by selection 

 by Hemming (1964, Annot. Lep. (4) : 130) : Stalachtis phaedusa Hiibner, 1818, ibid. 

 1 : 9, pi. [3], figs 13, 14. 



This is one of those cases in which a nominal genus remained until recently without a validly 

 selected type-species owing to the fact that, when the currently accepted type-species was 

 selected, the author making the selection (Scudder) erroneously treated the Verzeichniss and 

 not the Zutr&ge as the work in which the generic name was first published. The portion 

 (signature 2, page 27) of the Verzeichniss containing the name Stalachtis was published in 

 1819, and from the species there placed in this genus, Scudder in 1875 (Proc. amer. Acad. 

 Arts Sci., Boston, 10 : 270) selected Papilio phi aer, J779J \Uitl. Kapellen 3 (17) : 9, 



pi. 197, fig. F). Unfortunately, that species was not included in the genus Stalachtis in the 

 volume of the Zutrcige published in the previous year. From the two species cited in the 

 Zutrdge, I have selected Stalachtis phaedusa Hiibnei 1 pi species. This species is com- 



monly considered to be congeneric with Papilio pltlegia Cramer, the false type set up by 

 Scudder, and accordingly its selection as type-species avoids any disturbance in existing 

 nomenclatorial practice. 



STALACTIS Westwood, [1851], in Doubleday, Gen. diurn. Lep. (2) : pi. 73 (an Incorrect 

 Subsequent Spelling of Stalachtis Hiibner, 1 s 1 s , 



STALLINGSIA Freeman, 1959, Lepid. News 12 (3/4) 87. Type-species by original desig- 

 nation : Megathymus maculosa Freeman, 1955, Amer. Mas. Novit. No. 1711 : 10. 



STAPHYL US (iodman & Salvin, [1896], Biol, centr .-amer . , Lep. Khop. 2 : 429. Type-species 

 by original designation : Helias ascalaphus Staudinger, 1876, Verh. zool.-bot. Ges. Wien 

 25 : 116. 



The taxon represented by the nominal species Helias ascalaphus Staudinger is currently 

 treated subjectively on taxonomii grounds as a subspecies of the taxon represented by the 

 older-established nominal spirits Carcharodus mazans Reakirt, 1866 (Prov. Acad. nat. Sci. 

 Philad. 1866 : 335.) 



STEMPFFERIA Jackson, 1962, Hull. Br. Mus. nat. Hist. (Ent.) 12 (3) : 157. Type-species by 

 original designation : Stempfferia carcassoni Jackson, 1962, I.e. 



STEREMNIA Thieme, 1905, Berl. ent. Z. 50 : 137. Type-species by selection by Hemming 

 (1943, Proc. R. ent. Soc. Lond. (B) 12 : 25) : Pedaliodes (?) polyxo Godman & Salvin, 1880, 

 Trans, ent. Soc. Lond. 1880 : 129, pi. 3, figs 8 q\ 8a$. 



STEROMA Westwood, [Dec. 1850], in Doubleday, Gen. diurn. Lep. (2) : pi. 66, fig. 6. Type- 

 species by monotypy : Steroma bega Westwood, [Dec. 1850], in Doubleday, Gen. diurn. 

 Lep. (2) : pi. 66, fig. 6 [text (: 400) published in July 1851]. 



STEROPES Boisduval, [1832], in d'Urville, Voy. "Astrolabe " , Faune ent. 1 (Lep.) : 167. 

 Type-species by selection by Lindsey (1925, Ann. ent. Soc. Amer. 18 : 101) : Papilio iacchus 

 Fabricius, 1775, Syst. Ent. : 533. 



The name Steropes Boisduval is invalid, as it is a junior homonym of Steropes Steven, 1806, 

 (Me"m. Soc. imp. Nat. Moscou 1 : 166). 



Formerly, the name Steropes was used in an entirely incorrect sense as the equivalent of 

 Carter ocephalus Lederer, 1852. The history of this mistake has been explained in detail in 

 the note on that generic name. 



STEROSIS Felder (C.) & Felder (R.), [1865], Reise Fregetta " Novara ", Lep. Rhop. (2) : 219. 

 Type-species by monotypy : Sterosis robusta Felder (C.) & Felder (R.), [1865], ibid., Lep. 

 Rhop. (2) : 219, pi. 27, figs 10, 11. 



The taxon represented by the nominal species Sterosis robusta Felder & Felder is currently 

 treated subjectively on taxonomic grounds as being the same as that represented by the older-
