The Lake Waccamaw .specimen was taken in heavy undergrowth 

 of bushes in short-leaf pine woods, while on St. Simon's Island the 

 species occurred in very few numbers among dead leaves under 

 live oaks. In the latter situations there was practically no ground 

 vegetation owing to the constant shade of the oak groves. A par- 

 ticular search was made for the species elsewhere as well as on St. 

 Simon's Island and all seen were secured. The date for the Smith- 

 ville record given by Scudder is November 22, so the species is seen 

 to be present, where found, from late August to the latter part of 

 November.

The above synonymy is evident after examining all the typical 

 material involved, 91 the individual and to an extent geographic varia- 

 tion found in the species probably being responsible for Scudder's 

 confusion. The general size, form of the cerci, furcula, supra-anal 

 and subgenital plates, caudal femora and tegmina, as well as certain 

 features of the coloration, are found to be variable in the series of 

 eighty-one specimens from seventeen localities before us. The 

 largest specimens are from the Missouri valley region, but the 

 variation in this respect at any locality represented by a series is 

 seen to be very considerable. It is quite possible that the acquisition 

 of more material from the Mississippi and Missouri valleys will 

 show the desirability of recognizing two races of this species, one a 

 western one to which the name blatchleyi (proposed to replace Bruner's 

 preoccupied Pezotettix occidentalis, described from Omaha, Nebraska) 

 should be limited, and the other to which typical walshii, with 

 amplectens as a synonym, would be applied. There can be no 

 question but that these forms, if recognizable, are but races of one 

 species, for which the name walshii must be used. At present we 



91 Morse has already placed blatchleyi in the svnonvmv under amplectens.
