According to my conclusion, without having seen the type, 

 the name borealls falls as a synonym. 4

On a Long- Winged or Caudate Phase of Neotettix 



proavus Rehn and Hebard (Orth.). 

 By HENRY Fox, Entomological Assistant, U. S. Bureau of 



Entomology.* 



In 1916 Rehn and Hebard described Neotetti.v proavus on 

 the basis of five specimens from the southeastern United 

 States. f It is very evident from the remarks of these authors 

 that they had to do solely with material in which the tegmina 

 and wings were greatly reduced and with the caudal pro- 

 longation of the 'pronotum not exceeding the tip of the abdo- 

 men. During the early summer of 1917 the present writer 

 found this species not uncommon locally in wooded areas in 

 the vicinity of Clarksville, Montgomery County, Tennessee. 

 Most of the specimens collected at this locality, and now in 

 the collection of the writer and of the local -field station of 

 the Bureau, agree with the form described by Rehn and He-

4 No answer was received from Dr. Walker to a letter asking for 

 the loan of his type for examination. Very recently Blatchley received 

 from Walker'one of his two specimens of AT. borcalis, and finds, as I 

 have above noted, that it is the same as my slnnfrons.
