 long; carina between metapleurum and metasternum present ante- 

 riorly as a short ridge; propodeum medially with sharp, medium-

Fabricius stated that the type of P. notator was from "America 

 meridionali Dom Smidt. Mus. Dom. Lund." The material reported 

 by Fabricius from "South America" collected by Smidt, in the Lund 

 and Sehestedt collections in Copenhagen, is in most cases labeled "Es- 

 sequibo, Smidt." Essequibo is both a river and a county in British 

 Guiana. The type of P. notator is labeled "Am. mer. Smidt." It is 

 probably from the lot of material collected by Smidt in Essequibo. 

 The species is not, however, yet known from additional specimens 

 from that area.
