883. POLYCHROA. 

 1820. Billb., Euum. Ins. 78 : Obrinus, Ancoeus. 

 Obrinus may be taken as the type. 



884 POLYCTMA.* 



1862. Scott in Feld., Vt-rh. Zool.-bot. Gesellsch. Wien. xii. 490: 

 Felder says that Scott [in litt. ?J proposes this for the 

 species, which Felder there places in Holochila. Felder 

 does not adopt the name, because it is not appropriate for 

 most of the species. See also Erina. 



885. POLTDORUS.* 



1832-33. Swains., Zool. 111. ii. 101 : Aristolochine (Thoas), Poly- 

 dorus, Polytes (Polystes, Romulus). The last two speci- 

 fied as types. 



As the name is founded upon that of one of the species inchided 

 in it, it ialls. Moreover, it is preoccupied through Polydora (Bosc, 

 Worms, 1802). See Pachlioptera. 



886. POLYGONIA. 



1816. Hiibn., Verz. 36: Egea (triangulum, i. album), c. aureum, 



Progne, c. album. 

 1858. Kirb., List Brit. Rhop. : employs it for c. album only, which 



therefoi'e becomes type. 

 1872. Scudd., Syst. Rev. 9 : specifies c. aureum as type, but incorrectly. 

 See Grapta and Comma. 



887. POLTGONUS.* 



1822-26. Hiibn., Exot. Schmett. ii. : Ami/ntas (lividus). Sole spe- 

 cies, and therefore type. 

 The name is preoccupied through Polygona (Schum., Moll. 1817), 

 and is very close to Hubner's own Polygonia. See Acolastus. 



888. POLYOMJIATUS. 



1805. Latr., Sonn. Buff. xiv. 116: betulas, quercus, pruni, Boeticus, 

 rubi, Argus, Thetis (Adonis), Endymion (Meleager), 

 Corydon, Arion, Areas (Erebus), Cyllarus, Semiargus 

 (Acis), Argiolus, Alsus, Dorilas (Myopa), Phlseas, vir- 

 gaurece. Corydon alone is figured. 



1807. lb.. Gen. Crust, et Ins. iv. 206 : divides the group into sec- 

 tions, specifying a few, as follows : I. «, betulte, quercus, 

 and others not in previous list ; b, Boeticus, Endymion 

 (Meleager), rubi, Phlseas, virgaureae ; II. Argus, Cory- 

 don, Alsus.
