COLEOPTERA AND LEPIDOPTEBA COMPARED. 205 



as a whole, are the most soft and naked of all the 

 lepidopterous caterpillars. The looper moths, as they 

 are called, or the Geometria of Linnaeus, are well known 

 to move by a sort of leap ; and almost the only Co- 

 leoptera, which really possess this property, belong to 

 the Monilicornes, where we have the whole family of 

 HalticidcB, with their thickened thighs. The largest 

 beetles are among the Capricornes ; and the largest 

 Lepidoptera are types of the Bomby tides. In both these 

 groups, also, we find the antennae more developed than 

 in any other insects : in some of the Capricorn beetles, 

 they are five times the length of the body; while, in 

 the silk moths, or Bornbycides, their structure is parti- 

 cularly complicated. 



(179-) We must not be surprised, however, in sub- 

 mitting a natural group to many and diversified tests, 

 that some analogies are more remote than others ; and 

 that others can be traced only in one stage of the insect, 

 and not in another. To show this more clearly, as an 

 inevitable consequence of general analogies, we shall 

 next compare the tribes of the Coleoptera with the 

 families of the Diurnes, or true butterflies.
