1869. Butl., Cat. Fabr. Lep. 194: employs it for Actaeon, with 

 which he places imperialis (Venus). 



This, therefore, would become the type, but imperialis became in 

 1832 the type of Areas, leaving Mavors for the type of this group. 



1040. TllERlUS.* 



1820. Dalm. in Billb., Enum. Ins. 75 : Apollo, Mnesonyme. 



The name is preoccupied through Theria (Hiibn., Lep. 1816) and 

 Thereus (Ib.). See Parnassius and Doritis. 



1041. TIIESPIA.* 



1858. Wallengr., K. Vet. Akad. Forh. xv. 77 : Bohemanni. Sole 

 species, and therefore type. 



Doubtless intended by Wallengren to supplant his Ptychopteryx 

 (preoccupied), but it falls before Teracolus. 



1042. THESTIAS.* 



1836. Boisd., Spec. gen. 590 : Pyrene (JEnippe, Pirene), Marianne, 

 Vollenhovii (Bailee), Venilia. 



* Subsequently used by Doubleday and others, but the name is pre- 

 occupied through Thestius (Hiibn., Lep. 1816). See Ixias. 



1043. THESTIUS. 



1816. Hiibn., Verz. 78: Gabriela (Gabrielis), Pholeus (Pholeus, 



Archytes), Hyacinthus, Ematheon, Ly cabas (Lycabus). 

 Pholeus may be taken as the type. 



1044. THESTOR. 



1816. Hiibn., Verz. 73: Protumnus (Petalus), Ballus. 



1857. Led., Wien. Ent. Monatschr. i. 32: employs it for Ballus and 



others, not including Protumnus. 

 J861. Staud., Cat. Lep. Eur. 3 : follows Lederer. 

 1869. Butl., Cat. Fabr. Lep. 174 : uses it for Protumnus and others. 

 1871. Kirb., Syn. Cat. 345: follows Lederer. 



Ballus, however, cannot be taken as the type, since previously to 

 Lederer's action it had been selected as the type of Tomares (q. v.) ; we 

 must therefore follow Butler in considering Protumnus as the type. 



1045. THISBE. 



1816. Hiibn., Verz. 24: Ireneea (Belise). Sole species, and there- 

 fore type. 



Since used similarly by Bates and Kirby.
