GENERIC NAMES OF BUTTERFLIES 439 



Eropus published by themselves earlier in the same year, that name having been found to be 

 invalid under the Law of Homonymy. 



THECLA Fabricius, 1807, Mag. f. Insektenk. (Illiger) 6 : 286. Type-species by selection by 

 Swainson ([1821], Zool. Illustr. (1) 2 : pi. 69) : Papilio betulae Linnaeus, 1758, Syst. Nat. 

 (ed. 10) 1 : 482. 



During the latter part of the XlXth century the name Thecla Fabricius was widely misused 

 for the Strymonid Hairstreaks consequent upon the mistaken action of Scudder (1872, 4/A 

 Ann. Rep. Peabody Acad. Sci. 1871 : 50) in rejecting Swainson's type-selection of Papilio 

 beiulae Linnaeus and in seeking to set up Papilio spini [Dennis & Schiffermiiller] as type- 

 species ; in the same period the true Theclids were normally placed in Zephyr us Dalman, 18 16 

 (a nominal genus bearing a name which is a junior objective synonym of Thecla Fabricius, its 

 type-species also being Papilio betulae Linnaeus). 



THECLINESTHES Kober, 1891, Tijdschr. Ent. 34 : 316. Type-species by monotypy : 



Plebeius (Theclinesthes) eremicola Rober, 1891, ibid. 34 : 316. 

 In the following year Kober published a figure of the type-species (1892), ibid. 35 : pi. 5.

 THECLIOLA Waterhouse, 1912, Index zool. 2 : 299 (an Incorrect Subsequent Spelling of 



Thecliolia Strand, 1910). 



THECLIOLIA Strand, 1910, Ent. Itundsch. 27 : 162. Type-species through Section (i) (re- 

 placement names) of Article 67 : Thecla w-album Knoch var. eximia Fixsen, 1887, in 

 Romanoff, Mini. Up. 3 : 271, pi. 13, fig. 2. 



The name Thecliolia was introduced by Strand as a replacement for Felderia Tutt, [1907], 

 which is invalid under the Law of Homonymy. 



THECLOPSIS Godman & Salvin, [1887], Biol, centr .-amer . , Lep. Rhop. 2 : 99. Type-species 

 by original designation : Thecla lebena Hewitson, 1868, Descr. new Spec. Lycaenidae : 9.

THEMONE Westwood, [Oct. 1851], in Doubleday, Gen. diurn. Lep. (2) : pi. 72, fig. 9. Type- 

 species by monotypy : Helicopis pais Hiibner, [1820], Samml. exot. Schmett. 2 : pi. [16]. 



Westwood 's text (loc. cit. (2) : 462) relating to the name Themone was published in December 

 1851, i.e. two months after the issue of plate 72. Here also the sole included species was 

 Helicopis pais. 



THEOCHILA Field, 1958, Proc. U.S. nat. Mils. 108 : 106. Type-species by original desig- 

 nation : Pieris maenacte [sic] Boisduval, [1836], (Roret's Suite a Buffon), Hist. nat. Ins., 

 Spec. gen. Lep. 1 : 517. 



THEOPE Doubleday, 1847, List. Spec. lep. Ins. Brit. Mus. 2 : 6. Type-species by selection by 

 Scudder (1875, Proc. amer. Acad. Arts Sci., Boston 10 : 280) : Polyommatus terambus

THEOPE Moore, 1857, in Horsfield & Moore, Cat. lep. Ins. Mus. East India Coy (1) : 234. 

 Type-species by monotypy : Mycalesis (?) himachala Moore, 1857, ibid. (1) : 234. 



After describing the above species as being doubtfully a member of the genus Mycalesis 

 Hiibner, Moore added that this species might " be separated under the generic name of Theope 

 Moore ". The name Theope Moore, 1857, is invalid, as a junior homonym of Theope Doubleday, 

 1847. Two replacement names have been published, the earlier and valid name being Ethope 

 Moore, [1866] {Proc. zool. Soc. Lond. 1865 (3) : 770).
