After carefully comparing specimens of this species, from many 

 parts of the United States, with the descriptions and figures above 

 cited, I feel convinced that they are all to be referred to that 

 described by DeGeer. Dr Dohrn, Linnaea Entomologica, vol. xiv, 

 p. 220, cites a species from Georgia for the Ploi. brevipennis Say, but 

 Say's species came from Pennsylvania and does not agree with the 

 description of Dr. Dohrn. It seems to me to be a new species which 

 I have never seen.

A somewhat immature specimen now remains in the collection. 

 It seems to be rare, although widely distributed in the United 

 States.
