Family XXX. DYNASTIDdS. 
This name has the same origin as the English word dynasty, which 
means sovereignty, and it has been given to these beetles on account of 
[Fig. 38.) their generally large size and im- 
posing aspect. The family con- 
tains the largest insects in (he 
order of Coleoptera, some of the 
tropical species being more than 
two inches and a half long, and 
more than an inch in thickness. 
We have one species in the 
Southern States, the Dynastes Ti 
tyus, Linn. (Fig. 38), which is two 
inches long, of a greenish -gray 
color, with scattered black spots; 
there is a long horn on the head 
and another on the thorax, with 
a smaller one each side of it ; 
the female has only a tubercle 
on the head. Another species, 
dynastkh tityus, Linn. after Riiey. the Ayloryctes satyr us, Fab., an 
inch or more in length and of a black color, and with an upright horn 
on the head of the male, is not uncommon in the Northern and Middle 
States. Its larvae are sometimes injurious to ash trees by feeding upon 
their roots. 
Iu the genus Ligyrus, Burm., the head has two very small tubercles, 
and the general aspect is much like the common chafers, but they are 
distinguished at once by their black color. The L. relictus, Say, is a 
very common species. It is three-quarters of an inch long ; its larva
