THE BUG. 



Moat of na have a prejadiee agaioat bugs, which has aome reaaon 

 for its exiatenee in the diaagreeable oharaoter of man; that bear 

 thia name, bat the rematkable adaptations to their mode of life 



shown b; aome of theae in- 

 sects will awaken onr inter- 

 est in spite of oniselves. 



The aqnaeh-bng, shown 

 enlarged in Fig. 1, givea a 

 good idea of the charaoter- 

 iatic form of the body, and 

 also of the pecniiar wings, 

 and ia easily found on sqnash- 

 vinea. It ia too amall for 

 the month-parts, bat these 

 are well shown by the com- 

 mon Cicada, or harveat fly 

 (Fig. 2), while if theteacher 

 can have one of the "giant 

 water-bngs " (Fig. 3), she 

 will find it invalnablf . One of the moat interesting species, and 

 therefore one that we cannot affoi d to do withoat, is the lively 

 water-boatman (Fig. 4), which children can collect from the ponds. 



The squash-bug has a small, pointed head. It has 

 head, thorax, and abdomen. The abdomen is flat on the 

 back and rounded below. The head is much lower than 

 the back of the thorax and the abdomen. There are 

 three pairs of legs, used for walking, not for jumping. 

 There are two pairs of wings. The forward pair are 

 thickened in front and thin behind, and they overlap. 

 They are called wing-covers. The hind wings are thin. 



Some will nndonbtedly fail to see from their specimens th&t the 

 wing-ooyers are half membranons, bat the " giant " will make this 

 very clear.
