NATURAL HISTORY OF INSECTS. 



PIRATE-BUGS (Reduvidae). In this Family the body is 

 usually elongated and provided with four wings, but in a few 

 species these are either rudimentary or entirely wanting; the 

 antennae are of moderate size ; the ocelli are present ; the feet 

 are three-jointed; and the beak when folded back is not 

 received in a channel. 



A few species are aquatic, but the greater number are terres- 

 trial and feed upon other insects. The Banded Robber (Fig. 

 154) belong to this Family. 



CHINCH-BUGS (Lygasidse). These insects are provided with 

 four wings; the antennae are conspicuous and four-joined, 

 the terminal joint being as thick as the preceding one; the 

 ocelli are sometimes absent. 



These insects are terrestrial and usually subsist on the 

 juices of plants, but a few species are said to be predaceous. 

 The Chinch-bug (Fig. 85) is occasionally very destructive to 

 wheat and corn; it is of a black color, with white wings which

are marked with a black spot on the outer edge of each. The 

 False Chinch-bug (Fig. 301) also belongs to this Family. 



SQUASH-BUGS (Coreidds). These insects are furnished with 

 four wings; the antennae are conspicuous and four-j6inted, 

 the terminal joint being as thick or thicker than the preceding 

 one; the ocelli are present. 



These insects are terrestrial and usually 

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

 cies are said to be partially predaceous. The 

 Squash-bug (Fig. 163) is sometimes very de- 

 structive to squash and pumpkin vines; it is
