Family XXX. DYNASTID^. 



This name has the same origin as the English w ord dynasty, which 

 means sovereignty, and it has been given to these beetles on account of 



their generally large size and im- 

 posing aspect. The family con- 

 tains the largest insects in the 

 order of Coleoptera, somo of the 

 tropical species being more than 

 two inches and a half long, and 

 more than an inch in thicluiess. 

 We have one species in the 

 Southern States, the ])ynnstes Ti- 

 tyiis, 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, \\'ith 

 a smaller one each side of it; 

 the female has oulj- a tubercle 

 on the head. Another sjiecies, 

 the Xyloryclcs satyrus, 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 larv.ie are sometimes injurious to ash trees by feeding upon 

 their roots. 



In the genus Llgynis, Burm., the head has two very small tubercles, 

 and the general aspect is nuich 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 j its larva 



Dykastes Titvus, Linn. :— after Riley.
