852 ZOOLOGY— INSECTS. 



the names I have adopted in that work where they relate to the same divis- 

 ion, genus, or species, except where I find that I am in error. 



It is proper to remark here that this work relates almost exclusively to 

 the species named by Linne, De Geer, and Thunberg, yet the author seizes 

 the occasion to present a somewhat detailed synopsis of his arrangement of 

 the family. While I cannot agree in every respect with this arrangement, 

 yet I think it must be admitted that he has made a marked advance in sys- 

 tematizing this troublesome family, and that entomologists must adopt much 

 that he has presented. 



Although I am inclined to think my own arrangement should be some- 

 what modified, I cannot adopt his division into eleven subfamilies, if they 

 are intended to stand as divisions of equal value, or as representing corre- 

 sponding variations. The grouping does not differ very materially from 

 that of most recent authorities, although the characters used as his chief 

 guides are somewhat different. This would indicate that the larger groups, 

 as now established, are natural, as the same result is reached, no matter from 

 what stand-point our investigations are made. 



In my synopsis, I have divided the family into two primary divisions, 

 which I call, and I think correctly, subfamilies, while the next divisions, 

 corresponding, in part, with Stal's, I have termed groups. This method, I 

 think, corresponds more closely with the nature of the characters that sep- 

 arate these divisions, and renders the arrangement more systematic than 

 either that of Walker or Stal. 



The subfamilies given by Dr. Stal are as follows : — 



Pli y mat idee ; 



Pampliagidcc ; 



Acridiidce; 



Truxalidce ; 



CEdipodidce ; 



Pneumoridce ; 



Codopternida ;• 



Tift igidce; 



arranged in the order here given ; also Proseopidce, Mastacidce, and Chorcc- 

 typidce, whose position in his system the author does not give.
