GENERIC NAMES OF BUTTERFLIES 419 



The name of the type-species, Strabena smithii was published by Mabille as new on two 

 occasions, first in 1877, as shown above, second, in 1878 {Bull. zool. Soc. Fr. 3 : 81). 



In a paper published in 1887 (in Grandidier, Hist. phys. nat. pol. Madagascar 18, Lep. 1 : 

 10, 22) Mabille stated that the type-species of this genus was Satyvus tamatavae Boisduval, 

 [1833], but this was incorrect, for, as shown above, the type-species is Strabena smithii Mabille 

 by monotypy. 



STRYMON Hiibner, 1818, Zutr. z. Samml. exot. Schmett. 1 : 22. Type-species by selection by 

 Kiley (1922,7. Bombay nat. Hist. Soc. 28 : 472) : Strymon melinus Hiibner, 1818, ibid. 1 : 

 22, pi. [21], figs 121, 122. 



This is another of the cases in which a generic name was published by Hiibner in two 

 works which were published within a very short time of one another, in which he placed 

 different species in the genus so named. The works concerned were volume 1 of the Zutrdge 

 and the Verzeichniss respectively. Scudder, while realizing that much of the text of the 

 butterfly portion of the I 'erzeichniss was published after 1816, the date given on the title-page, 

 decided nevertheless it would be best in the state of information then available to treat all the 

 names in question as having been published in that year — this decision being taken, as he said, 

 for "convenience and uniformity " (1875, Proc. amer. Acad. Arts Sci., Boston 10 : 98); he 

 therefore accorded priority to names published in the Verzeichniss over names published in the 

 Zutrdge. For Strymon as of the Verzeichniss he selected Hesperia titits Fabricius, 1793, 

 (Ent. Syst.3 : 293) as type 1-. early as 1872 (4th Ann. Rep. Peabody Acad. Sci. 1871 : 53). 



That species was not cited in the Zutrdge as belonging to the genus Strymon, and as the first 

 volume of the Zutrdge was published in 1818, it has priority over the name Strymon as publi- 

 shed in the Verzeichniss which was published, as is now known, in 1819. Thus, Scudder's 

 type-selection based on the I'erzeichmss is invalid. It was not until 1922 that one of the 

 Zutrdge species was selected as the type-species of Strymon, Riley in that year selecting 

 Strymon melinus Hiibner as type-species. 



The case of the name Strymon Hiibner was brought to the attention of the Commission in 

 1934 jointly with the name Bithys Hiibner, 1818. No action was then taken by the Commis- 

 sion, the application being withdrawn temporarily in order to permit of a further examination 

 of the issues involved. The Commission's decision was later embodied in Opinion 165 (1945, 

 Opin. int. Comm. zool. Nom. 2 : 359-374). This case was resubmitted to the Commission 

 in a revised form in 1954, m which, so far as the name Strymon Hiibner was concerned the 

 Commission was asked to place the name Strymon Hiibner on the Official List with Strymon 

 melinus Hiibner as type-species. This proposal was approved by the Commission in Opinion 

 541 (published in 1959, loc. cit. 20 : 87-102), the name Strymon Hiibner being placed on the 

 Official List as Name No. 1332. 



STRYMONIDIA Tutt, [April 1908], A'at. Hist. Brit. Butts 2 : 483. Type-species through 

 Section (i) (replacement names) of Article 67 : Thecla thalia Leech, [1893], Butts China 

 Japan Corea (2) (text-pt 3) : 367 ; (plate-pt 3/4) : pi. 30, fig. 15 <J. 



The name Strymonidia was published by Tutt as new on two occasions, first, as shown 

 above, in April 1908, second, two months later (June 1908, Ent. Rec. 20 (6) : 143). 



Tutt introduced the name Strymonidia as a replacement for the name Leechia Tutt, [1907], 

 which is invalid under the Law of Homonymy. 



As has been explained in the note on the name Chattendenia Tutt, [1908], a name which has 

 hardly ever been used, a First Reviser choice has been made giving precedence over that name 

 to the quite widely used name Strymonidia Tutt, published on the same date in the same work.
