SUBFAMILIES OF ACRIDIIDJ-:. 



In Eruuner von Wattenwyl's ' Eevision of the Orthoptera,' 

 published at Greueva in 1893, he admits nine subfamilies of the 

 present group. Of these, the second and fourth (PNEUMOEiNiE 

 and Peoscopin.^) are exclusively confined to South Africa and to 

 Tropical America respectively ; while the eighth, the PamphagiNtE, 

 is not yet recorded from India, though it is probable that some 

 representatives may occur in the northern or nortli-western 

 portions. The other subfamilies are all more or less fully 

 represented.
