mentum, which Is acuminate in front ; the head and thorax are 

 armed with large horns in the males ; the first joint of the pos- 

 terior tarsi is not elevated, and there are no stridulating or- 

 gans. Our only species is Dynastes Tityus Linn., found in 

 the Southern States. It is over two inches long, of a greenish 

 gray color, with black spots scattered irregularly over the ely- 

 tra. Dynastes Hercules Linn. , one of the giants of the family, 

 is about six inches long. 



The genus Cetonia and its allies are flower beetles; their 

 mandibles are feebly developed and in part membranous and 

 concealed with the other oral organs beneath the clypeus ; and 

 in flying they "do not raise or expand the elytra, as most Cole- 

 optera do, but pass the wings from the side, tinder the elytra, 



which do not at all 

 embrace the sides of 

 thebocty." (Leoonte.) 

 The immense Go- 

 liath beetles of the 

 \\cstorn coast of 

 Africa belong to the 

 genus Goliathits, in 

 which the clypeus of 

 the males is generally 

 Fig ' 413> forked or armed with 



horns. Dr. Harris has proposed the name of Hegemon "for 

 the subgenus, including the princely Scarabceus Goliathus of 

 Linnaeus, together with the still more magnificent Goliath u* 

 Drurii of West wood, and the G. Caricus of Gory and Per- 

 cheron." Of Hope's subgenus Mecynorlifn<i. the Scarabaeus 

 Polyphemus of Fabricius is the type; it is velvet given above, 

 with a pale buff head and markings, and is two and a half 

 inches long, exclusive of the horns. Dr. Harris has also 

 described as new to science M. Savagil which has a velvet 

 green thorax, and velvet black elytra, with tawny bands and 

 spots; it is about two inches long. The G. Goliflmx is per- 

 haps the largest of all the Coleoptera ; specimens measuring 

 nearly four inches. Dr. G. A. Perkins of Salem, Mass., who 

 collected a large part of the fine series of specimens of these 

 Goliath beetles in the Museum of the IV a body Academy of
