In size and in the venation of the wings .this species agrees with Say's 

 description of P. caudatus. But Say's species is " pale testaceous," has 

 a " blackish transverse line between the antennas," and is not stated to 

 have the metathorax black.

This is the first species of the genus discovered in America, the 

 Gotiatopus? alatus Cress. (Tr. Am. Ent. Soc, iv., 193) evidently belong- 

 ing to the genus Dry inns of Walker and Haliday.
