8. Hind wings immaculate below cernes. 



I liml wings with light markings below 9.

Veins pale, uniting and producing the spots sabuleti. 



10. Marks on hind wings below distinct draco.

T. baracoa Lucas. 



It is found in Florida. 

 T. alcina Skinner. 



From Colorado. Dr. Skinner thinks that this may be rhena Edw., 

 but we have not seen the type. 

 T. mystic Scudder. 



Occurs in the eastern United States. 

 T. sylvanoides Boisduval. 



( >ccurs on the Pacific coast and mountains. 

 T. siris Edwards. 



< >ccurs in the western United States, Rocky Mountains to the 

 Pacific coast. I doubt the distinctness of this form from sylvanoides. 

 Both sexes are a little darker, but I see no other difference. 

 T. vibex Hiibner {stigma Skinner, not Staudinger). 



Occurs on our southern border. 

 T. brettus Boisduval & Leconte. 



Inhabits the Southern States. I think this is only a varietal form 

 of vibex. The dark markings in the male are more extended in vibex, 

 but they vary. I have specimens from Jalapa, Mexico, labelled vibex 

 by Mr. Schaus, which are indistinguishable from Texan brettus. God- 

 man and Salvin also are of my opinion (Biol. Cent. Am., Rhop., ii, 

 480, 1900). 

 T. chusca Edwards. 



Described from one male from Arizona. I have not seen the 

 species. 

 T. cernes Boisduval & Leconte. 



Inhabits the eastern United States. 

 T. draco Edwards. 



From the mountains in the West ; southern Colorado, Idaho,. 

 Wyoming, Crater Lake, Oregon. 

 T. mardon Edwards. 



Washington (Neumoegen collection, Brooklyn Museum). 

 T/sabuleti Boisduval. 



From the western United States, California, Nevada, Arizona.
