Represented in the National Museum by two males ; one 

 from San Bernardino, Paraguay (Fiebrig, collector), the other 

 from the Williston collection, through the American Museum 

 of Natural History, presumably collected in Brazil by H. H. 

 Smith. 



Van der Wulp, in 1887, believed that acuminata is distinct 

 from producta; the difference, however, was in the length of 

 the fourth abdominal segment of the male, which is pretty 

 certainly a highly variable matter here, as it undoubtedly is in 

 halisidotcF.
