206 NATURAL ARRANGEMENT OF INSECTS. 



itself, being so little adapted to resist external injury, 

 protects its body by artificial means, and lives concealed 

 within a rolled leaf: the HesperidcB, in fact, are the 

 soft-skinned butterflies, just as are the Malacodermes 

 among the Coleoptera. The next analogy — or that 

 between the Monilicornes and the ErycinidcB — 

 is, perhaps, one of the strongest that can be found. 

 The caterpillar of a Cassida, or tortoise beetle, so 

 completely resembles that of an Erycinian butterfly 

 that they might both be taken for examples of the 

 same tribe of insects. Great developement of the 

 appendages to the head invariably accompanies all 

 those animals which represent the Capricorn beetles ; 

 whether these appendages are horns, as in quadrupeds ; 

 crests, as in birds ; or antennae, as in winged insects. 

 Hence it is, that the antennae of the Satyridce, or wood 

 butterflies, are longer in proportion to their body, than 

 those of any other Lepidoptera in existence. Our own 

 cabinet, peculiarly rich in this splendid tribe, enables 

 us to state this fact with confidence; and the analogy 

 receives still greater confirmation, by the larvje of these 

 butterflies being provided, in almost every instance, 

 with spines on their heads, or appendages to their tails. 

 It thus appears that the arrangement we now propose, 

 for the first leading tribes of the Coleoptera, is in perfect 

 unison with that system upon which we have arranged 

 the animal creation, throughout which it cannot be 

 doubted that one uniform plan, perfect in all its parts, 

 must prevail.
