512 CAUDELL 



The nymphs, which are apparently in the last stage, usually 

 have the outer surface of the posterior femora wholly black on 

 the basal two-thirds, generally relieved b}' two oblique pale 

 bands, and the inner surface marked by two oblong fuscous 

 spots. 



This species has been recorded from the Northern United 

 States, Labrador, Greenland, and Norway.
