Papipappus clarazianus Saussure. 



Tucura Catanlil, Department of Limay Centro, Territory of 

 Neuquen. (Lizer.) Two males, one female. 



This species was described from the region between the Rio Negro 

 and the Rio Chubut, which area lies southeast of where the present 

 material was taken. No other records are known for the genus and 

 species. 



Paulinia acuminata (DeGeer). [Cceloptema acuminata of authors.] 



Buenos Aires. One female. [Hebard Coll.] 



Subfamily OMMEXECHIN.^. 



Ommexecha servillei Blanchard. 



Misiones. January, February and October, 1911, November, 



1910, December 20, 1910. (Jorgensen.) Four males, eight females 



[three pairs in copula]. 



From this material it is evident that the species is dimorphic in 

 wing length, all three pairs taken in copula differing individually 

 in this respect, two pairs having the males brachypterous and the 

 females macropterous and the other pair having the male macropter- 

 ous and the female brachypterous. Of the unmated specimens one 

 male and one female are macropterous and four females brachyp- 

 terous. In the brachypterous individuals the apices of the tegmina 

 vary from straight to strongly uncinate. From the present evidence 

 it would appear that germari Burmeister is merely the macropterous 

 phase of the present species, but we do not wish to establish this 

 synonymy until we are better acquainted with Brazilian material 

 of the genus. All of the present series are of a brownish coloration, 

 some more blackish brown than others. 



Spathalium stall Bolivar. 



Posadas, Misiones. September, 1912. (Schrottky.) One female. 



Graea monstrosa Bruner. 



La Cumbre, Prov. of Cordoba. (Lizer.) One adult female, one 

 immature female.

 tween Bahia Blanca and Cordoba.

 Coryacris angustipennis (Bruner). 



Posadas, Misiones. April 8, 1910. (Jorgensen.) One female.
