 male genitalia are the same. 

 T. brizo Boisduval & Leconte. 



Occurs in the northern Atlantic and Pacific states, Washington to

 rowly marked brizo with dark ground color. 

 T. icelus Lintner. 



Occurs in the Atlantic States. 

 T. ausonius Lintner. 



Described from Albany, New York and never since found. It is

 T. martialis Scudder. 



Occurs in the Atlantic states. 

 T. terentius Scudder & Burgess 



Occurs in the southern Atlantic states. I cannot differentiate 

 Lintner' s ncevius of Florida from this. 

 T. persius Scudder. / 



Occurs in the Atlantic states. 

 T. pernigra Grinnell. 



Mr. Grinnell has obligingly loaned me the unique type. The

 T. afranius Lintner. 



Occurs in the Rocky Mountains, Montana to Nevada.
