Family N^EOGEID^E. 



The two. species in our fauna were listed under "Hebrus" in the last 

 edition and placed under the family "Veliidae," which the species re- 

 semble; in fact, the "Hebrus americanus" Uhl. is really a "Microvelia."

 N. burmeisteri Leth. & Sev. (pusillus Burm.) "United States" (Uhl). 



N. concinnus Uhl. Chester, Arlington (Coll); W T estfield IV, 19, VII 

 (Bno). There may be really only a single species in New Jersey anO 

 the two names here listed may both refer to that one (Bno). 



Family REDUVIID^E. 



Called "pirate bugs" and "assassin bugs" from their predatory habits, 

 which make them decidedly beneficial. They have long legs, the anterior 

 often enlarged for grasping, a very narrow head with small, though promi- 

 nent eyes, and a short, very stout curved beak, which is rigid and cannot 

 be folded back against the head. These characteristics render the family 

 an easily recognizable one, although there is a great variety in form and 

 general appearance. A number of them have become adapted to life in 

 cities, and, on shade trees, are of material service in reducing the num- 

 ber of plant feeders.
