248 FRANCIS HEMMING 



1934 (Gen. Names hoi. Butts 1 : 108), I maintained the name Agriades for the " Arctic Blue " 

 as a provisional measure, pending the submission of an application to the Commission for 

 relief under the Plenary Powers. At the same time, I adopted for the " Arctic Blue " the 

 correct specific name glandon Prunner in place of the name orbitulus Prunner in its customarily 

 misidentified sense. I did this with reluctance and only because at that time the Commission 

 was not prepared — indeed, hardly considered itself authorized — to use its Plenary Powers 

 in relation to specific names as well as to generic names. 



In the following year (1935) I submitted the contemplated application to the Commission, 

 by which it was approved at its Session held at Lisbon later that year. Under that decision 

 the Plenary Powers were used to designate Papilio glandon Prunner, 1798, to be the type- 

 species both of Agriades Hiibner, [1819], and of Latiorina Tutt, 1909. Financial and admini- 

 strative difficulties delayed the promulagtion of the Lisbon decisions and it was not until 1946 

 (Opin. Int. Comm. zool. Nom. 2 : 483-494) that Opinion 173 embodying it was published. 

 The action described above was completed in 1954 {l° c - c ^- 6 : 2 5~4°) when by the Ruling 

 given in Opinion 270 the Commission, noting that, under the Ruling given in Opinion 173, the 

 name Latiorina Tutt, 1909, was invalid as a junior objective synonym of Agriades Hiibner, 

 [1819], placed it on the Official Index of Rejected and Invalid Generic Names in Zoology as 

 Name No. 67. 



LAVATHERIA Verity, 1940, Le Farfalle diurn. d'ltalia 1 : 11, 22. Type-species by original 

 designation : Papilio lavatherae Esper, [1783], Die Schmett. 1 (Bd 2) Forts. Tagschmett. : 

 148, pi. 82, fig. 4 6*. 



LAXITA Butler, 1879, Trans, linn. Soc. Lond. (2), Zool. 1 (8) : 546. Type-species by mono- 

 typy : Taxila teneta Hewitson, [1861], III. exot. Butts 2 : [89], pi. [45], figs 3, 4 $. 



Butler, when establishing Laxita as a subgenus of Abisara Felder (C.) & Felder (R.), i860, 

 cited only Taxila teneta as belonging to this taxon, though he indicated that he regarded 

 certain other species, which he did not specify, as belonging to Laxita also ; he then went on 

 to discuss the type-species of Taxila Doubleday. Butler's remarks were rather incoherent, 

 but there is, I consider, no doubt that, as stated above, Taxila teneta is the type-species by 

 monotypy ; if it were to be considered that Butler should be regarded as having included in 

 Laxita also a species mentioned in the discussion on Taxila, the species Laxita teneta would 

 still be the type-species of Laxita, that species having been expressly so selected by Kirby in 

 [1881] (in Zool. Rec. 16 (year 1879) (Ins.) : 143). 



LEBADEA Felder (C), 1861, Nova Acta Leop. Carol. 28 (No. 3) : 28. Type-species by 

 selection by Scudder 1875, Proc. amer. Acad. Arts Sci., Boston 10 : 203 : Limenitis ismene 

 Doubleday, [1848], Gen. diurn. lep. (2) : pi. 34, fig. 2. 



The text giving the type-locality for Limenitis ismene was published after Doubleday's 

 death by Westwood ([1859], in Doubleday, Gen. diurn. Lep. (2) : 276) after Doubleday's death. 



LECTILES Birket-Smith, i960, Bull. Inst, franc. Afr. noire (A) 22 : 966. Type-species by 

 original designation : Lectiles collitorum Birket-Smith, i960, loc. cit. (A) 22 : 968. 



Stempffer has expressed the opinion (in lift., 13th September 1963) that the taxon represent- 

 ed by the nominal species Lectiles collitorum is the same as that represented by the older-estab- 

 lished nominal species Liptena (Tetrarhanus) schoutedeni Berger, 1954 Ann. Mus. Congo 

 belg. (N.S. in 4T.0), Sci. zool. 1 : 308, figs 10 (genit), 11, 12, 13 (imago), from which it is not 

 separable either by the genitalia or superficially. 



LEDARGIA Houlbert, 1922, in Oberthur, Etud. Lep. comp. 19 (No. 2) : 157, 162. Type-species 

 by monotypy : Arge yunnana Oberthur, 1891, Etud. ent. 15 : 13, pi. 3, fig. 21 q*. 



The taxon represented by the nominal species A rge yunnana is currently treated subjectively 

 on taxonomic grounds as forming part of the same species-group as the taxon represented by 

 the nominal species Melanargia leda Leech, 1891 (Entomologist 24, Suppl. : 57). Of these 

 names leda Leech was published in June 1891 and yunnana in July 1891. Accordingly, the 

 species as a whole is known by the specific name leda Leech, the taxon named yunnana by 

 Oberthur being treated as a subspecies of the taxon represented by Melanargia leda Leech.
