Bess. a. diff. — This Odynerus differs from 0. pedestris and 

 Pennsylvanicus, by the coarse punctuation of first segment, etc. ; 

 from the 0. perennis, by its thorax, shorter, less strongly punc- 

 tured than the first segment, by its less elevated head, its less 

 prolonged form, etc. ; from the 0. texensis, by its less angulate 

 and less rugose metathorax ; by its first segment more coarsely 

 and more equally punctured throughout; by the 2d less strongly 

 punctured, especially along its posterior border, etc. — From all 

 by its whitish, not yellow ornaments.
