The present geographic race differs from typical Nemobhis carolinus 

 in being usually of paler coloration over the arid or semiarid portions 

 of its distribution, while in these specimens the great majority are 

 somewhat more slender. 



The series from the state of Vera Cruz, Mex,, differs from carolinus 

 in being more russet in general coloration, the dorsal abdominal 

 spots of the females being, moreover, very large.
