Oxyblepta boMsii (GigUo-Tos). 



1895. S[tenopola] bohlsii Giglio-Tos, Zoolog. Jahrbiicher, Abth. Syst., 

 VIII, p. 813. [Paraguay.] 



Misiones. May 20, 1910. One female. 



The previous records of this species were from Chapada (Bruner) 

 and Corumba (Rehn; Bruner), Brazil; Paraguay (Giglio-Tos), 

 Sapucay, Paraguay (Bruner; Rehn), and Resistencia nel Chaco, 

 Argentina (Giglio-Tos) . 



*Aleuas vitticollis St&l. 



1878. A[leuas] vitticollis Stal, Bihang till K. Svenska Vet.-Akad. Handl., 

 V, No. 4, p. 69. [Sao ("San") Leopoldo, Rio Grande do Sul, Brazil; Mon- 

 tevideo, Uruguay.] 



Misiones. February 24, 1910. One male. 



This species has also been recorded from Sapucay, Paraguay 



(Rehn; Bruner), and Corumba, Matto Grosso, Brazil (Rehn; Bruner). 



♦Aleuas brachypterus Bmner. 



1906. Aleuas brachypterus Bruner, Proc. IJ. S. Nat. Mus., XXX, p. 667. 

 [Sapucay, Paraguay.] 



Misiones. February 2, 1911. (No. 39.) "On water plant." 

 One female. 



The only previously known locality for the species was that of the 

 type. It seems very probable to us that this is the female sex of 

 vitticollis, the material before us, consisting of four females, differing 

 from vitticollis males only in such characters as are sexual, using the 

 term in the sense of known sexual differences in the closely allied 

 A. gracilis. 



Aleuas lineatus StS.1. 



1878. A[leuas] lineatus StM, Bihang till K. Svenska Vet.-Akad. Handl., 

 V, No. 4, p. 70. [Buenos Aires; Uruguay.] 



Caucete, Prov. of San Juan. Elev. 567 meters. January 13, 1909. 

 One male, one female. 



San Ignacio, Prov. of Mendoza. Elev. 1,235 meters. April 4, 

 1908. One male, one female. 



These specimens are seen to have longer tegmina and wings than 

 two pairs from Carcarana, when compared with the same. In the 

 males from Caucete and San Ignacio the tegmina surpass the tips of 

 the caudal femora by very nearty or quite the pronotal length, while 

 in the Carcarana males the difference is hardly ijiore than half of the 

 same. In the females the discrepancy is less decided, but still quite 

 apparent. 



This species is known to range from Sapucay, Paraguay (Bruner),.
