 the purpose of preparing the manuscript for that portion of the 

 Biologia Orthoptera dealing with the locusts or short-horned 

 grasshoppers, a number of very interesting forms have been 

 encountered. From among these, two have been singled out as 

 being unusually remarkable. 



Since preparing the table for separating the subfamilies of 

 these insects that were known at the time to be represented in 

 the territory covered by that great work, an additional sub- 

 family for North America has come to light. This occurred 

 among some very interesting things that were taken in south-

 Acrididae belonging to South American genera, as well as those 

 indigenous to the region itself. It is too bad therefore that no 

 more careful field work has been done in the way of amassing 

 material belonging to this greatly neglected family in that sec-
