 Fieber's arrangement* is as follows (supposed to be descending):

 Xyodea. 

 Tribe II. — Harmoptera - Forficulinn. 



Walker, in his "Catalogue of the Saltatorial Orthoptera (Dermaptera)," 

 remarks that he prefers the system of Fischer, who considers Acridium to 

 represent the highest group. 



The latest and perhaps the best arrangement (if it is to be considered ■ 

 as descending) is that of M. Brunner de Wattenwyl, as follows, and is simply 

 a reversal of the arrangement of Burmeister and Scudder : 



Forficularia. 



Blattaria. 



Mantodea. 



Phasmodea. 



Acridiodea.

At the time my. "Notes on the Saltatorial Orthoptera of the Rocky 



Moiuitain Regions " was written I had not seen, or, at least, my attention had

as descending, it agrees exactly with the order I adopted in that paper, which
