ORTHOPTERAACRIDIDAE OEDIPODA WHEELER1I. 879 



5 , length 25 millimeters. Illinois. 



In the structure of the head and pronotum similar to (E. Carolina, but 

 differs in being smaller, the elytra and wings less ample, and the former less 

 less densely reticulated ; the pronotum behind the middle being subalutace- 

 ous ; and in the color of the wings. The posterior angle of the lateral 

 lobe of the pronotum rounded." 



Although this description differs considerably from the description of 

 my (E. cincta, which is found in Illinois, I am rather inclined to believe they 

 are identical ; otherwise I am wholly unacquainted with it.

Stal places CE. discoidea in Saussure's genus Hippiscus, and, as this is a 

 very closely allied species, it should probably be placed in the same genus, 

 though, in some respects, it appears to correspond more closely in generic 

 characters, with his Pycnodictija. 



Hippiscus. plioenkopterus, Burm., will therefore be its new name, there- 

 by remanding another name to the list of synonyms. 



There are four specimens in the collection of 1872. 



OEDIPODA CORALLIPES, Hald. 



This, in all probability, will have to follow (E. discoidea to Hippiscus. 

 I find but one specimen of this species in the collection, which was taken 

 in Nevada. It would appear from this fact that it does not extend very 

 far southward in the intermontane area. 



OEDIPODA WHEELERII , sp. nov. 

 PLATE XLIV, PIG. 1. 



Has much the appearance of (E. trifasciata, but is quite distinct, and pos- 

 sibly is not congeneric as Stal has limited the genera. The upper portion of 

 the head rounded and smooth; seen from the front, elliptical; eyes small,
