ACRlDIDil OF NORTH AMERICA NOT FOUND IN THE UNITED 



STATES. 



This part contains descriptions of the genera and species of Acrididce 

 which are found in North America, but not in the United States. It in- 

 ckides not only those found on the continent, as in British America, Mexico, 

 Honduras, &c., but also those found in the West Indies. Many species 

 found in the United States and described in the first part are also found 

 beyond the limits either north or south ; none of these are included in this 

 part, as it is intended to contain only those not found in the United States. 

 It will be seen, by an examination, that ahhough but ninety-four species are 

 described, yet these belong to thirty diiferent genera, more than the number 

 belonging to the United States fauna. This would indicate that when these 

 regions, especially the tropical ones, are thoroughly explored, the number of 

 species will be largely increased. 



As I have had an opportunity of seeing but few of these species, I have 

 in most cages copied the fullest and most complete description I could find, 

 preferring those by the most recent authorities.' Where they are rejjre- 

 sented by good figures, I have in some cases — as those in Charpentier's "Or- 

 thoptera descripta et depicta" — added some characters from these figures 

 when the author has omitted to mention them in his description. 



I have arranged the genera according to the plan adopted in the first 

 part so far as it was possible for me to do this without specimens ; but I 

 have not attempted to arrange the species in this order, nor have I attempted 

 to add synoptical tables.
