Information with the unique type is to the effect that it was taken 

 from stones of a very similar coloration. 

 * Ommexeclia giglio-tosi Bolivar. 



1899. 0[mmexecha] Giglio-Tosi Bolivar, Revista Chilena Hist. Nat., Ill, 

 pp. 54, 55. [Caiza, Aguairenda, and San Francisco, Bolivian Chaco.] 



Jujuy, Prov. of Jujuy. April, 1911. Five males, three females. 



Embarcacion, Prov. of Salta. April, 1911. Three females. 



This series of specimens show two types of structure, one with the 

 pronotum more sellate than the other, but we do not feel warranted 

 in separating them specifically. Both forms are in the Jujuy series, 

 but only that with the more sellate pronotum in the Embarcacion lot. 



The wings are pale azure on the disk, the apex very lightly infumate, 

 with the transverse veins of the discoidal and adjacent portion of the 

 axillary fields seal brown. 



The above localities are all from which the species is known. 

 *Ommexecha germari Burmeister. 



1838. 0[mmexecha] Germari Burmeister, Handb. der Entom., II, abth. II, 

 pt. 1, p. 655. [Brazil.] 



Misiones. August 4, 1909. One female. 



This individual is inseparable from representatives from Sapucay, 

 Paraguay. 



The present species has been recorded from Brazil (specifically 

 Sao Leopoldo [Bolivar], Porto Allegre [Karsch], and Corumba 

 [Bruner] ), Paraguay (specifically Villa Rica [Giglio-Tos] and Sapucay 

 [Rehn] ) and the Misiones. This is the first record of the species 

 from Argentina. 

 Ommexeclia servillei Blanchard. 



1837. Ommexecha Servillei Blanchard, Ann. See. Entom. PVance, V, p. 613, 

 pi. XXII, figs. 2, 3. [Province of Corrientes, Argentina.] 



Misiones. May 12, 1910; November 9, 1910; December 12 and 

 17, 1910. (No. 20.) Four males, two females. 



All of these specimens are brownish in coloration and we have 

 provisionally retained the name servillei for them, although we have 

 little doubt that topotypes of Serville's virens, from Buenos Aires, 

 will show that name to have been based on a green color phase of 

 the present insect. 



Previous records of servillei are from Porto Allegre, Rio Grande do 

 Sul (Karsch), Sierra Geral, Santa Catharina (Karsch), Sao Paulo 

 (Bruner), Reboucas (Rehn), Corumba, Matto Grosso (Bruner), 

 Matto Grosso (Karsch), Brazil; Asuncion and San Bernardino, 

 Paraguay (Bruner), Sapucay, Paraguay (Rehn, as virens), and 

 Misiones and Corrientes, Argentina.
