THE INSECTS OF NEW JERSEY. 153 



Most of the species resent being handled and will, if they get a chance, 

 puncture the hand that holds them, or they may "bite," on general prin- 

 ciples, if they alight on an exposed surface. The "bite" or puncture is 

 severe and poisonous, often causing intense pain and more or less swell- 

 ing, which may persist for a long time. A few species live in houses, 

 and in the Southern States one of them attacks human beings and is 

 known as the "big bed-bug." Another species has the more satisfactory 

 habit of feeding on common bed-bugs and other household pests. This, 

 while of good size, is seldom seen, because it covers itself with dust and 

 fluffy material that accumulates in corners which make it resemble a 

 little wad of waste. 



Sub-family EMESIN^. 



This is a series of very slender species with enormously lengthened 

 legs which has given rise to the common name "thread-legged" bugs. The 

 anterior legs are fitted for grasping, and. slight as the insects are, they 

 depend for their food upon species unable to resist them. They are not 

 usually abundant. 



PLOIARIOLA Reut. 



P. errabunda Say. (Cerascopus.) Taken in adjacent States and sure to 

 occur in New Jersey. 



EMESA Fab. 



E. longipes De G. Throughout the State VII-IX, not common. Occurs 

 on bushes at the edges of fields and about barns and is said to prey 

 on spiders. 



BARGE Stal. 



B. annulipes Stal. Staten Island (Ds) ; Lakehurst V, VII, IX, X (div). 



B. simplicipes Uhl. New York and probably New Jersey; both species 

 under planks or logs in fields (Bno). 



LUTEVA Dohrn. 

 L. Carolina H. S. Will probably be found in New Jersey (Bno). 



Sub- family 



ONCEROTRACHELUS Stal. 



O. acuminatus Say. Greenwood Lake V, Roselle Park I, sifting (Brb) ; 

 Jamesburg XII, 1 (Dn) ; Pt. Pleasant VIII, 8 (Bno).
