Tetrastichus polynemae Ashm. Hyperteles polynemae Ashm. The nymphs live among submerged plant stems. Their ex- tremely slender legs, long swaying bodies, and leaflike gill plates, together with a sober color pattern of greens and browns, render them very inconspicuous when in their native haunts. In aquariums they are rather shy, and do not feed under observa- tion so readily as do many other genera. I have observed them eating some of the larger eutomostraca and smaller dipterous larvae (Corethra and Chironomus). Since the nine species occurring in or regional in New York State have all been described several times in recent and avail- able papers, and since the females are well nigh indistinguish- able, and determinations must at present be based on the malei* and chiefly on the form of the termioal abdominal appendages of the males, I have not thought it worth while to give descrip-.
