 Argoides minimus of 1845 was based on Or- 

 nithoidichnites minimus of 1841. This was a 

 composite species, a part of which was assigned 

 to Palamopus rogersianus of the present work 

 (Macropterna vulgarly of E. Hitchcock.) The 

 remaining part must bear the name given it in 

 1845.

 mann may not belong here.
