The species described by me under the name ot scalaenus 
on page 201 of Bul. 86 should be considered as a distinct species, 
differing from the 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.
