GENERIC NAMES OF BUTTERFLIES 253 



The name Leptoneura Wallengren is invalid, as it is a junior objective synonym of Lira 

 Hiibner, [1819]. 



LEPTOPHOBIA Butler, 1870, Cistula ent. 1 : 35, 45. Type-species by original designation : 

 Pieris eleone Double-day, I March 1847], Gen. diurn. Lep. (1) : pi. 6, fig. 6 ; [April 1S47 , 

 ibid. (1) : 50 (2nd issue) [sine descr.]. 



LEPTOPTERA Scudder, 1875, J'roe. amer. .lead. Arts Sri., Boston 10 : 204. Type-species by 

 original designation : Amnosia decora Doubleday, Aug. 1841;, Gen. diurn. Lep. (2) : pi. 51, 

 fig. 4 [text published by Westwood in ' July 1850], in Doubleday, ibid. (2) : 260 {sine descr.)]. 

 This name has had an unsatisfactory and confusing history, as the result entirely of 

 Boisduval's habit of putting manuscript names into an irregular circulation and of failing 

 later to provide those names with a definite nomenclatorial status. The history of the 

 present case is as follows. The name Leptoptera firsl appeared in print in [842 [Ann. Soc. 

 ent. /■>. 11 (4) : 298) in a casual reference by Lucas m the paper in which he established 

 the genus Godartia. Lucas provided no diagnosis to the then-unpublished genus Leptoptera, 

 merely stating that its type-species was " Leptoptera decora Boisduval (inedit.) ". Both the 

 name Leptoptera and the spe< ific name tie, ora failed to acquire any status in nomenclature in 

 Lucas's paper, since neither was then provided with a description or other indication. The 

 next occasion when either of these names appeared in print was in [844 [List Spec. lep. Ins. 

 Brit. Mus. 1 : 88), when Doubleday published the specif* name decora in the combination 

 Amnosia decora, which he attributed again to Boisduval. So published, this name appeared 

 in a bare list of names and act ordingly remained a nomen nudum ; the generic name Amu 

 which here made its first appearance in the literature, w.is ,iiso a nomen nudum, being pub- 

 lished without any description or indication and without any duly established nominal 

 species. It was not until i84<) that the nominal species Amnosia decora was validly estab 

 Itshed, it being figured by Doubleday in the Gen. diurn. Lep. in that year. The name 

 Leptoptera did not appear in the literature after [842 until it was published by Scudder in 

 1875 with Amnosia decora Doubleday as type-spe< ies. S< udder erroneously accepted Lu< .is 

 as having validly published this manuscript name of Boisduval's ; .is he was the lust author 

 to accept this name as validly published, he must himself he treated as its author as of 1875. 

 This is of no practical importance, for, as he pointed out, the designation of Amnosia </> 

 Doubleday as type-species makes Leptoptera a junior objective synonym of Amnosia Double- 

 day, [1849]. 



LEPTORIA Stephens, 1835, ///. Brit. lint., Haustellata 4 1404 (an Incorrect Subsequent 

 Spelling of Leptosia Hiibner, 1818, misinterpreted as being the equivalent of Leptidea Billberg, 

 1820). 



As explained in the note under the name Leptosia Hiibner, that name was formerly, though 

 incorrectly, widely used as the equivalent of Leptidea Hillberg with Papilio sinapis Linnaeus 

 as type-species. This was the only species cited by Stephens when on the occasion cited 

 above he used this generic name in the misspelled form Leptoria. 



LEPTOSIA Hiibner, Zutr. z. Samml. exot. Schmett. 1 : 13. Type-species by selection by 

 Scudder (1875, Proc. amer. Acad. Arts. Sci, Boston 10 : 204) : Leptosia chlorographa 

 Hiibner, 1818, ibid. 1 : 13, pi. [9], figs 47, 48. 



The taxon represented by the nominal species Leptosia chlorographa is currently treated 

 subjectively on taxonomic grounds as being a subspecies of the taxon represented by the 

 older-established nominal species Papilio nina Fabricius, 1793 (Ent. syst. 3 (3) : 194). 



The name Leptosia was included by Hiibner both in the Zutrdge and in the Verzeichniss 

 and was formerly treated as having been first published in the Verzeichniss ; this was un- 

 fortunate because of the significant difference in the species included in this genus in these 

 two works. In the early and middle parts of the XlXth century the name Leptosia was 

 widely used for Papilio sinapsis Linnaeus, a usage which was consistent with the usage in 

 the Verzeichniss (in which Hiibner included a nominal species Papilio lathyri Hiibner — which
