 The species described by me under the name 01 scalaenus 

 on page 201 of Bui. 86 should be considered as a distinct species, 

 differing from tlie European form in size, coloring, and particularly 

 in the metatarsal proportions. Named in honor of Prof. J. G. 

 Needham. I have seen specimens from New York, Indiana, Kansas, 

 and Washington.
