in commerce, presents the appearance of small violet grains 

 which look like seeds, but on examining them carefully their 

 animal nature is easy to be perceived, especially if they are 

 allowed to soften a little in water. 



OEDEE OETHOPTEEA. 



Insects of the order Orthoptera have jaws like Coleoptera ; 

 they have two kinds of wings, but the elytra are soft, and the 

 hind wings are folded like a fan, instead of being folded 

 transversely, like those of Coleoptera, Their metamorphoses 

 are incomplete, as in the order Hemiptera. The Orthoptera 

 having jaws cannot suck blood like some of the Hemiptera ; but 

 they are often very formidable to the crops. 



The forficulaor earwigs, are Orthoptera furnished with a kind of 

 pincers at the end of the abdomen, which they open 

 with a menacing air when irritated, but with which 

 they are incapable of doing any inj ury . They live in 

 society^ and are very destructive to flowers 

 and fruit, but never get into anyone's ear, as 

 is vulgarly imagined. The internal auditory 

 canal is furnished in man, with stiff hairs 

 and an acrid substance which is generally 

 sufficient to prevent any insect from getting 

 into it. 



Tho mole-cricket is so called, partly because it resembles the 



other crickets, which 

 are Orthoptera, and 

 partly on account of 

 the shape of its fore 

 legs, which have 

 some resemblance to 

 those of the mole,
