THE wings of beetles are covered and concealed by a pair 

 of horny cases or shells, meeting in a straight line on 

 the top of the back, and usually having a little triangular or 

 semicircular piece, called the scutel, wedged between their 

 bases. Hence the order to which these insects belong is 

 called Coleoptera, a word signifying wings in a sheath. 

 Beetles * are biting-insects, and are provided with two pairs 

 of jaws moving sidewise. Their young are grubs, and un- 

 dergo a complete transformation in coming to maturity. 



At the head of this order Linnaeus placed a group of 

 insects, to which he gave the name of Scarab^us. It 

 includes the largest and most robust animals of the beetle 

 kind, many of them remarkable for the singularity of their 

 shape, and the formidable horn-like prominences with which 

 they are- furnished, — together with others, which, though 

 they do not present the same imposing appearance, require 

 to be noticed, on account of the injury sustained by vegeta- 

 tion from their attacks. An immense number of Scaraba*- 

 ians (Scarab^eid.e), as they may be called, are now known, 

 differing greatly from each other, not only in structure, but 



* Beetle, in old English, betl, bytl, or bitel, moans a biter, or insect that bites.
