Mr. Oberholser restricts the Genus Antrostomus BONAP. to A. carolinensis 

 and considers the other members of the group to belong to a new genus, Setochalcis 

 (Bull. 86, U. S. Nat. Mus., 1914, p. u). I am unable to verify his conclusions with 

 the slight material at my disposal and have therefore decided (provisionally) not to 

 make the change.
