NOTES ON THE VARIATION IN COLOR OF CEDIPODA 

 CORALLIPES AND CEDIPODA CINCTA. 



BY G. M. DODGE, GLENCOE, DODGE CO., NEBRASKA. 



Rev. Cyrus Thomas, in his Acrididae of North America, page 132, 

 says : ' k There are no permanent characters by which to distinguish alco- 

 holic specimens of (Edipoda coraltipcs, Haldemanii^ paradoxa and rugosa 

 from each other.'' He therefore considers them the same. Probably 

 CE. discoidca might be considered as another variety of the same. This 

 mucn named grasshopper is abundant in Nebraska from the middle of 

 June to about the middle of August. Owing to its large size (which is 

 exceeded here only by the huge, wingless B. magnus) and colored wings 

 it is one of the most conspicuous of our Orthoptera. It would be 

 difficult, if not impossible, to breed grasshoppers from the egg ; the 

 only way, therefore, to establish the relationship of different varieties, is 

 by comparing a large number of fresh specimens, seconded by close 

 observation of their habits. I have therefore collected and compared a 

 large number of specimens of this species during the past summer. I 

 find but little difference between them except in the color of the wings 

 and hind femora and tibia? ; but these vary considerably, as the following 

 table will show : 



Variety A. Wings yellow ; inside of hind femora and hind tibiae yellow. 

 " B. Wings red ; inside of hind femora and hind tibiae yellow 



( (E. paradoxa). 

 " C. Wings yellow ; inside of hind femora and hind tibiae bright 



red ( OE. Haldemanii). 

 " D. Wings red ; inside of hind femora and hind tibiae bright red. 

 " E. Wings yellow ; inside of hind femora whitish, ribs brown ; 



hind tibiae yellow. 

 " F. Wings yellow • inside of hind femora brown, lower sulcus 



blue ; hind tibiae yellow.
