Il8 CAUDELL. [5 12 ] 



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 by 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.
