Misiones. January 5, 1909; February 16, 1910; November 9, 

 1909; December 2-30, 1909-1910. (Nos. 26 and 33.) Four males, 

 eight females. 



Buenos Aires. May 6, 1907. One female. 



Los Cisnes, Argentina. May 13, 1907. One female. 



This series shows considerable color and size variation, the most 

 striking of which is found in a single female from Misiones, which is 

 distinctly larger than the average of the species and has the proximo- 

 dorsal pale band on the caudal femora and the "hour-glass "-shaped 

 figure on the dorsum of the pronotum cream-buff, in striking contrast 

 to the remainder of the body color. 



This widely distributed species ranges south as far as the Rio 

 Negro region of Patagonia.
