Ligocatinus spinatus (Brunner). 



1878. A[m.aura] spinata Brunner, Monogr. der Phaneropt., p. 248, pi. V, 

 fig. 74a-6. [Buenos Aires.] 



Buenos Aires. February 26, 1909. Three females. 



This species has been recorded from Caiza, Bohvian Chaco, 

 San Lorenzo, Jujuy, and Buenos Aires, Argentina. We also have 

 before us a pair from Rosario, Argentina, collected by Bruner. 



* Ligocatinus olivaceus (Brunner). 



1891. Amaura olivacea Brunner, Verhandl. K.-K. Zool.-bot. Gesell., XLI, 

 p. 123. [Rio Grande do Sul, Brazil.] 



IMisiones. February 1, 1910; March 20, 1909. Two females. 



It seems probable that L. borrellii Giglio-Tos*^ is either a synonym 

 of the present species or certain of its supposed diagnostic characters 

 are not constant, such as the black median line on the dorsum of the 

 abdomen, which is strongly indicated in most of the specimens (five 

 in all) before us and almost completely absent in one. The character 

 of insertion of the lateral lobes of the pronotum is susceptible of much 

 latitude in individual interpretation, while the length of the ovipositor 

 and degree of angulation of the subgenital plate are not hard-and-fast 

 characters, as in the first case personal equation is a factor in deter- 

 mining the base of the ovipositor and in the second case the condition 

 of the specimen and the amount of flexure and compression of the 

 plate may lead to different conclusions. 



These specimens have been compared with individuals from 

 Sapucay, Paraguay, which is the only locality aside from the type 

 locality and that given above from which the species is known. 



*Ceraia cornutoides Caudell. 



1906. Ceraia cornutoides Caudell, Proc. U. S. Nat. Mus., XXX, p. 237. 

 [Sapucay, Paraguay.] 



IVIisiones. March 15, 1909. One female. 



This individual has been compared with topotypes. 



♦Vellea cruenta (Burmeister). 



1838. Ph[aneroptera] cruenta Burmeister, Handb. der Entom., II, Abth. II, 

 pt. 1, p. 691. [Rio Janeiro, Brazil.] 



Misiones. April 14, 1909. One female. 



This interesting species has been recorded from San Jose, Costa 

 Rica (Rehn), Demerara (Walker), Para (Walker), and Rio Janeiro 

 (Burmeister; Brunner). This is the most southern record for the 

 species.
