The type is unique. 



Subfamily OXYHALOIN^. 

 Chorisoneura minuta Saussure. 



Misiones. 1909. (Jorgensen.) One male. 



This and Saussure's record of a specimen from Corrientes are the 

 only ones with exact locality known for the species, which was 

 originally described from the Pampas. 



Family MANTID^. 

 SubfamUy ORTHODERIN^. 

 Mantoida burmeisteri (Giebel). 



Rio Salado, Prov. of Buenos Aires. Two males. 



These specimens fully agree with the individuals from the Misiones 

 previously examined by us, except that the coloration is somewhat 

 darker. The present record considerably extends the range of the 

 species, previously known only from Nova Friburgo, state of Rio 

 de Janeiro, Brazil, and the Misiones territory of Argentina. 



♦Mantoida tenuis (Perty). 



Mendoza, Prov. of Mendoza. January 17, 1905. (Haarup.) 

 Three males. 

 : This species was previously known only from Brazil. 



Orthoderella ornata Giglio-Tos. 



Jujuy, Prov. of Jujuy. December, 1911. (Jorgensen.) One male. 



This individual is the second male and third specimen known of 

 this remarkable genus and species. Originally described in 1897 

 from the female sex, taken at Caiza in the Bolivian Chaco, the next 

 record of its capture was made by Chopard,'' who first described the 

 male sex from a specimen taken at Santiago del Estero, Argentina, in 



7 Bull. Soc. Entom. France, 1911, pp. 141-143, figs. 1, 2.
