blackish-brown above and dirty-yellowish beneath, and meas- 

 ures about seven lines in length. The Three-striped Plant-bug 

 (Fig. 302) also belongs to this Family. 



PLANT-BUGS (Capsidve). These insects are terrestrial and 

 are provided with four wings; the ocelli 

 are absent; the antenna? are four-jointed, 

 with the terminal joint thinner than the 

 preceding one. 



The insects mostly subsist on the juices 

 of plants, but a few species are predaceous. 

 The Border Plant-Bug (Fig. 303) belongs 

 to this Family. 



SOLDIER-BUGS (Scutelleridse}. These insects usually have 

 a broad and flattened body, and are furnished with four wings; 

 the scutellum extends to or beyond the 

 middle of the abdomen; the antennae are 

 conspicuous and are from three to five- 

 jointed. 



The greater number of these insects sub- 

 sist on the juices of plants, but a few spe- 

 cies feed upon other insects. The Spined 

 Soldier-bug (Fig. 114) and the Negro-bug (Fig. 304) belong to 

 this Family. 



THRIPS (Thripidx). These insects are of 

 a small size, and are provided with four nar- 

 row wings, which are fringed; the mouth is 

 furnished with jaws; the ocelli are present; 

 and the antenna are from five to nine- 

 jointed. 



Some of these insects are vegetable feeders, 

 while others are said to prey upon other in- 

 sects. The Common Thrips (Fig. 161, adult; 

 Fig. 305, pupa)j belongs to this Family. 



BED-BUG (Membranaceidse). In this Family the body is 

 quite broad, and is sometimes provided with four wings, but 

 these organs are frequently wanting; the beak is received in 



Fig. 305.
