ANNOTATED LIST OF SPECIES. 



This list includes each species of adult Acridiidse secured, the 

 locality where taken, with brief notes on its abundance, habitat, and 

 habits in the territory traversed. In some cases data on the early 

 stages (in parentheses) are also included, but there are many, particu- 

 larly among the species of Schistocerca and Melanoplus, which can not 

 be identified with certainty. Dates and elevations will be found, if 

 desired, in the preceding list of localities. 



As has been stated, the entire territory lies in the Austral zones, 

 and data are as yet insufficient for the preparation of satisfactory lists 

 of species characteristic of each section of these zones. Consequently, 

 in this list relatively few statements will be found regarding zonal 

 distribution except in connection with the Transition or boreal faunal 

 elements. 



For several reasons it has seemed wisest to use, in the main, the 

 same terminology as in my first report (Pub. No. 18), but Trachy- 

 rhachis has been substituted for Mestobregma.
