thinking that it was Thecla raphaelis and not Dipsas flamen that had been designated as the 

 type-species.

 Matsumura published the name lietaporia as a new name twice in 1919, on each occasion 

 designating the above species as type-species. The first was in the serial cited above ; the 

 second in his work Tlious. Ins. Japan, Addit. on page 496 of volume 3. Luckily, the exact 

 1 Lite of publication is known in each case : Part 3/4 of volume 3 of the Ent. Mag. is dated 

 " March 1919 ", while volume 3 of the Addit. was published 23rd April 1919, as is noted in 

 manuscript on the endpaper of the copy in the library in the British Museum (Natural History). 

 The taxon represented by the nominal species Pieris moltrechti Oberthur is currently 

 treated subjectively on taxonomic grounds as representing a subspecies of the taxon represent- 

 ed by the older-established nominal species Pieris agathon Gray, 1831 (Zool. Miscell. (Gray) 

 1 : 33)-

 Linnaeus, 1763 (Amoen. acad. 6 : 409) through tin- designation by Hemming (1964, Annul. 

 l e P- (3) : 9 2 ) °f the specimen figured as fig. 2 on plate 36 of Clert k's It ones to represent the 

 lectotype of both of these species. 



The nominal genus Bia was established by 1 liibner solely upon bibliographical references to 

 the works of previous authors. The new nominal species Bia actoriaena was the sole species 

 recognized as belonging to this genus and is therefore the type-species by monotypy. 



The first of the bibliographical references cited bv Hiibner was to the nominal species 

 Papilio actorion Linnaeus. In the original description of thai taxon Linnaeus gave the follow- 

 ing reference to a plate in Clerck's Icones : " Clerk t.36 f.2 ". This plate formed part of the 

 second instalment of Clerck's Icones Ins. rar., whii h wis not published until 1764. It is no 

 matter for surprise however that Linnaeus should have referred to this plate before it was 

 published, for the preparation of Clerck's Icones was carried out under the close supervision 

 of Linnaeus and it was Linnaeus who supplied to Clerck the names inscribed on his plates 

 In the paper referred to above, I designated figure 2 on Clerck's plate 36 to represent the lecto- 

 type of Papilio actorion Linnaeus. Since, as explained above, Bia actoriaena Hiibner was 

 based in part on Papilio actorion Linnaeus, the type-material of Linnaeus's nominal species 

 forms part of the syntypes of Bia actoriaena. This made it possible to designate the specimen 

 representing the lectotype of Papilio actorion Linnaeus to represent also the lectotype of Bia 

 actoriaena Hiibner. This designation was made in the paper of mine referred to immediately 

 above. By these two lectotype-selections, the names Bia actoriaena Hiibner and Papilio 

 actorion Linnaeus became objective synonyms of one another, the nominal species bearing 

 these names having the same specimen as lectotype. 



BIAKA Joicey & Talbot, 191 7, Ann. Mag. nat. Hist. (8) 20 : 225. Type-species by original 

 designation : Biaka albidiscus Joicy & Talbot, 191 7, ibid. (8) 20 : 225. 



The nominal genus Biaka Joicey & Talbot is currently treated subjectively on taxonomic 

 grounds as representing the same genus-group taxon as that represented by the nominal 

 genus Mimene established by Joicey & Talbot on the same date and in the same paper. In 

 these circumstances, the relative precedence to be accorded to these names depends on the 

 choice of the First Reviser. This choice was made by myself in 1946 (Annot. lep. (3) : 86), 

 when, as First Reviser, I accorded precedence to the name Mimene over the name Biaka.
