nent ; the mesosternum is wide, thick, and subacute, but is 

 not much produced anteriorly ; and supplementary claws and 

 claw-joints (pseudonychia and plantula?) are found between 

 the nails of all the feet. 



Mr. Macleay, in the •'• Illustrations of the Annulosa of 

 South Africa," has referred some of the species to his genus 

 Coryphe (Gnathocera of Gory and Percheron), and has dis- 

 tributed the others into several sections ; and Mr. Hope* 

 has reduced them to smaller gi'oups, which may be called 

 subofenera. 



In a paper upon some of these African beetles, which was 

 published in June 1839, in the " Journal of the Essex County 

 Natural History Society," the name of Hegemon was proposed 

 for the subgenus including the princely ScarahcBus Goliatusf 

 of Linnaeus, together with the still more magnificent Goliathus 

 Drurii of Westwood, and the Cacicus of Gory and Percheron, 

 and also the females of the two latter, bearing the titles 

 of regiusi and princeps.^ Should this generical name be 

 adopted, it will enable us to restore to the Linna^an species 

 the specific name of which Lamarck and other naturalists 

 have deprived it. 



The subgenus Hes^emon may be distinguished by the fol- 

 lowing characters. Clypeus of the male armed in the middle 

 of its anterior edge with a short, recurved, forked horn, the 

 diverging branches of which are broad, thin, and obtuse ; 

 and on each side of the head, above the antennae, a broad 

 and thin toothlike projection, truncated at the summit. La- 

 brum wide, thin but horny, entire or rounded before, and 

 entirely concealed. Mentum widest before the middle, di- 

 vided into four lobes by a rounded emargination of the an-

t Linnaeus and Drury did not use the letter h in this name. It is to be regretted 

 that Mr. Macleay, who is justly styled the prince of modem entomologists, has ir* 

 terchanged the names of this and the following species, in his " Illustrations," 

 giving to the Goliatus the name o[ Drurii, and to the latter that of Goliathus. By 

 consulting Mr. Westwood's valuable edition of Drury's " Illustrations of Exotic 

 Entomolog}-," he would have avoided this mistake.
