827. Pentila. 



1847. [Boisrl. in] Doubl., List Br. Mus. 57 : undularis, and an un- 

 named species ; * but undularis was undescribed until 

 18G6, by Ilewitson. 



1851? Westw., Gen. Diurn. Lep., pi. 76: Zymna. 



1852. Boisd. in Westw., Gen. Diurn. Lep. 503 : undularis [still 

 inedited], Abraxas, Acrcea, and, with a query, Evander. 



Abraxas and Acrasa are figured (pi. 77), but as species of Liptena, 

 which Westvvood at the time of the publication of the plates considered 

 synonymous with Pentila. Zymna is placed in Miletvis. 



1866. Hewits., Exot. Butt. iii. 119: Mr. W. F. Kirby has kindly 



given me the following abstract of Hewitson's remarks, 



to which I have no personal access : — 



"Westwood in error used Liptena on pi. 77 (Gen. Diurn. Lep.), and 

 then adopted tlie name Pentila, applied by Boisduval to a part only, 

 not knowing that Tingra was synonymous. Tingra was earlier, but 

 uncharacterized, so Pentila must stand. Westwood's first species, 

 undularis, was Boisduval's type of Pentila ; but, as Westwood's dissec- 

 tions were made from tropicalis,t it should stand as Westwood's type. 

 Pentila includes tropicalis and Peucetia." 



1868. Herr.-SchaefF., Prodr. iii. 13: uses it in the manner indicated 



by Hewitson. 

 1871. Kirb., Syn. Cat. 335 : the same. 



As will be seen from the above, the generic name, when first pro- 

 posed, was founded upon undescribed species, and the characters of the 

 gentis were also withheld. It was first recognizable when Westwood 

 figured a species, Zymna, under that name ; but shortly afterward, and 

 before any further use of the generic name, he confessed lumself in 

 error in supposing this to belong to Boisduval's genus. The latter he 

 now characterized (probably from an examination of the first three 

 species on las list), and placed therein tlie species first referred to it 

 by Boisduval (though still unpublished), together with others, one of 

 them doubtless the unnamed species referred to the genus by Double- 

 day. Still later, in 18GG, Ilewitson described undularis; and since, 

 according to Kirby, it is congeneric with Acraja, it may most properly 

 be considered the type of this genus, which should date from 1852. 

 See Liptena and Tingra. 



828. Peplia. 



1816. Iliibn., Verz. 20: Lamis, caric89, Pelops (Pelope), Lysimon 



* Probably Abraxas or Acrsea. 



t This cannot be true, for Westwood remarks of tropicalis : " An insect 

 which I have not had an opportunity of examining," 1. c. 504.
