and therefore type. 

 1832-33. Ib., ib. ii. 59 : Peleus (Thetys). 



As the work was published in parts, Chiron was published before 

 Peleus. Marius is one of the synonymes of Chiron ; the generic name 

 being based upon it falls. See also Euglyphus and Megalura. 



658. MARMESSUS. 



1816. Hiibn., Verz. 81 1 Silenus (Alcides, Corax), Atymnus, Lisias- 

 Silenus and Atymnus belonging to the earlier Myrina, Lisias must 

 be taken as the type of Marmessus.

 chea), lole (Zosteria), Chiron (Chironias), Orsilochus 

 (Cinna). 



1844. Doubl., List Br. Mus. 86: employs it for Eleucha and Peleus

 Psidii, Phyllis.

1844. Doubl., List Br. Mus. 55 : employs it for Polymnia (Lysimnia), 

 and others. 



1847. Ib., Gen. Diurn. Lep. 128: divides the eighteen species which 

 he refers to this genus into two sections, placing Polymnia 

 in the first. 



1862. Bates, Linn. Trans, xxiii. 528 : restricts the group to Double- 

 day's first section, dividing that again into two sections, of 

 which Mechanitis proper is made to include " Polymnia 

 and its allies."

 fore type.
