the same species will attack both animals and plants. A common 

 species in our State is Leptocoris trivittatus, the box-elder bug. 



Family Pentatomidse (Stink-bugs). Every one who has lived in the 

 country, and especially all our fruit-growers, is well acquainted with 

 the stink-bugs, whose popu- 

 lar name is perhaps more de- 

 scriptive than elegant. They 

 are broad, flat bugs, generally 

 rather large, and mostly dull 

 colored. Most of them are 

 vegetable feeders, although 

 the family contains some pre- 

 daceous species. One of the 

 worst species of this family 

 with us is the Harlequin cab- 

 bage-bug, which sometimes 

 appears in great numbers, 

 and does much damage to 

 growing plants. 



Family Cydnidse (Burrow- 

 ing-bugs). These bugs have 

 a roundish, elliptical body, 

 usually black, or very dark in 

 color, and are found burrow- 

 ing in sandy places, under 

 sticks, stones, or near the roots or plants

strawberries. They do not confine themselves to these fruits, however, 

 as they sometimes attack potato vines and do much damage. 



Family Seutellepidse (Shield-back bugs). This is not a numerous 

 family. They are plant-eating insects, and somewhat resemble the 

 negro-bugs in general appearance.
