The generic name Pelion Kirby is invalid, as it is a junior objective synonym of Adopoea 

 Billberg, 1820. 



PELIOPIDAS Swinhoe, [1913], in Moore, Lep. ind. 10 (122) : 321 (an Incorrect Subsequent 

 Spelling of Pelopidas Walker, 1870.) 



PELLICIA Herrich-Schaeffer, 1870, CoryespBl. zool.-min. Ver. Regensburg 24 : 159. Type- 

 species by selection by Scudder (1875, Proc. amer. Acad. Arts Sci., Boston 10 : 243) : Pellicia 

 dimidiata Herrich-Schaeffer, 1870, ibid. 24 : 160. 



PELLICIA Plotz, 1879, Stett. ent. Ztg 40 : 176, 179. Type-species by original designation : 

 Pellicia macarius Herrich-Schaeffer, 1870, CorrespBl. zool.-min. Ver. Regensburg 24 : 160. 



Plotz clearly marked Pellicia as a new genus of his own by the use of the formula " n.g."; 

 this was no doubt because (as explained by Herrich-Schaeffer in 1870) it was he who had been 

 the first to propose this name in manuscript. He established this genus (: 176) in a key 

 without cited included species but shortly afterwards (: 179) he designated Pellicia macarius 

 Herrich-Schaeffer as type-species. 



The name Pellicia Plotz is invalid, as it is a junior homonym of the name Pellicia Herrich- 

 Schaeffer, 1870. 



PELOPIDAS Walker, 1870, Entomologist 5 : 56. Type-species by monotypy : Pelopidas 

 trxidea Walker, 1870, ibid. 5 : 56. 



The taxon represented by the nominal species Pelopidas midea Walker is currently treated 

 subjectively on taxonomic grounds as being the same as that represented by the older- 

 established nominal species Gegenes thrax Hiibner, [1821], (Samml. exot. Schmett. 2 : pi. [150]). 

 [It should be noted that this is the species commonly misidentified with that represented by 

 the nominal species Hesperia mathias Fabricius, 1798 (Suppl. Ent. syst. : 433). As Evans 

 has shown (1949, Cat. Hesp. Europ. Asia Australia : 440, 441), these species differ from one 

 another structurally ; in addition, these species, though overlapping in the Indian region, 

 have essentially different areas of distribution, thrax being centred in the Middle East, while 

 Sind and the Punjab are the westermost areas inhabited by mathias.']

 typy : Penetes pamphanis Doubleday, [1849], ibid. (2) : pi. 58, fig. 1 [the text ( (2) : 347)

When dealing with this genus in the text Westwood also included only the nominal species 

 Penetes pamphanis Doubleday.

PENTILA Westwood [Dec. 1851], in Doubleday, Gen. diurn. Lep. (2) : pi. 76, fig. 6. Type- 

 species by designation by the Commission under its Plenary Powers in Opinion 566 : Tingra 

 tropicalis Boisduval 1847, in Delegorgue, Voy. Afrique austr. 2 : 589. 



The case of the name Pentila Westwood is intimately bound up with that of the name 

 Liptena Westwood at the family-group-name level and some reference has been made to the 

 Pentila problem in the note on the name Liptena Westwood. These names resemble one 

 another in that each is the name of an important genus, both of which belong to the remarkable 

 group of African Lycaenids usually treated as belonging to an isolated subfamily to which 

 the name Lipteninae is currently applied. The nominal genera bearing these names also
