in some cases curved, in oth- 

 ers branched, antennae bent in 

 the middle, and composed of ten 

 joints, the last three or four of 

 which are leaf-like, and project 

 on the inside. They fly only at 

 night, spending the day upon 

 the trees, and feeding upon the 

 leaves. The grubs of the larger 

 kinds are six years in coming to 

 their growth, living all the time 

 trunks and roots of trees.

ScARAILEIDyE, Latr., OR ScARAB/EIAN FAMILY. - This 



very extensive Family embraces beetles which, though 

 differing in many respects, agree in having the antennae 

 ending in a knob composed of three or more leaf-like 

 pieces ; a projecting plate or clypeus, which extends for- 

 wards over the face like a visor ; a short, broad, thick, and 

 convex form ; legs fitted for digging, being toothed on 

 their outer edges ; and feet five-jointed. Some live mainly 

 upon or beneath the surface of the earth, and are hence 

 called Ground-Beetles ; others in the winged state are 

 found upon trees, the leaves of which they devour, and 

 are called Tree-Beetles ; and others, which in the perfect 

 state feed upon the juices of flowers, are called Flower- 

 Beetles. This group has been much divided, thus ap- 

 pearing in some works as many distinct families. 



The Genus Cofiris contains Dung- 

 Beetles, that enclose their eggs in 

 pellets of manure, which they roll 

 along with their hind feet, and at 

 length bury them. 



The Genus Pkan<zus comprises 

 very brilliantly colored species, the 

 males of which have horn-like prom-
