This is rather an early species and is found commonly on the flowers 
and leaves of the white water lily in the pine regions of Long Island and 
New Jersey. 
This species is apt to be confused with edentata but is a shorter 
insect with shorter antennal joints, more shining prothorax and shorter 
hind femora armed in both sexes with a distinct, though small tooth, 
which is absent in the latter species. From cincticornis, which it some- 
what resembles, it differs in shorter antennae, shorter and less strongly 
incrassate posterior femora armed below with a single tooth, more 
parallel form and narrower intercoxal process of the mesosternum.
