January. The present individual fully agrees with Chopard's 

 description and figure, except "that our specimen is of a brownish 

 instead of greenish phase of coloration. 



Subfamily M ANTING. 

 Brunneria brasiliensis Saussure. 



Misiones. February, 1911. (Jorgensen.) Three males. 



Mendoza, Prov. of Mendoza. (Haarup.) One male, one female. 



The Mendoza male is somewhat smaller than the Misiones individ- 

 ual of that sex, but otherwise inseparable. Two of the Misiones 

 males are of a brownish phase of coloration, while the other specimens 

 are greenish. Mendoza is the most southern locality from which the 

 species is known. 

 Coptopteryx argentina (Burmeister) 



Misiones. January, February, 1911; February 4, 1910, December, 

 1910. (Jorgensen.) Eleven males. 



Buenos Aires. (Lizer.) One female. 



These specimens vary considerably in size. The individual from 

 Buenos Aires is the smallest female of the species we have seen, its 

 measurements being: length of body, 52.5 mm.; length of pronotum, 

 17; greatest width of pronotum, 5.5; length of tegmen, 9; length 

 of cephalic femur, 14.1; length of caudal femur, 16.8. The form of 

 the pronotum in several is similar to or strongly approaches that of 

 the Cordillera de Mendoza individual previously mentioned by us.^ 

 In all of the present series the proximal portion of the marginal field 

 of the tegmina is opaque rufous. 



Coptopteryx gayi (Blanchard). 



Mendoza. (Haarup.) One male. 



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



Buenos Aires. (Lizer.) One male, one female. 



The Mendoza male has the limbs uniform greenish, while the 

 Buenos Aires pair has them of the same color much mottled with 

 brownish. 



Miopteryx argentina Saussure. 



Mendoza. November 18, 1904. (Haarup.) One male. 



San Cornelia. November, 1911. (Jorgensen.) One male. 



These apparently are the first exact records of this species, which 

 was described from the "Argentine Pampas" and since reported 

 from Brazil. The triangularly attenuate form of the cephalic 

 section of the pronotum of this species is distinctive.
