B. orthorJiyn chits Chitt., 1908-a, 2G. Smaller (G.2 7.5 mm.); femoral 

 tooth small, acutely produced distally, its entering angle rounded. De- 

 scribed from West Virginia. 



B. cuneatus Casey, 1910, 115. First and second funicular joints long 

 and equal in length, each a little shorter than the third and fourth 

 combined. Length 8.8 mm. West Virginia.

 and more gradually acute behind; second funicular joint of male but little 

 shorter than the first. Length 8.5 mm. New Jersey. 



The student may be in position to associate these names with 

 part of his specimens, but to us they seem unnecessary, as we 

 regard them at the most as mere varieties.
