nipnt at tbe extremity of the nlulomen, with which they deposit their egp;s. These species are commonly found 

 ou the ground, wliere tliL-y crawl about slowly. [They form the subgenus Val//in- of Scriba.] 



The second division, Golia/hides, is distinguished by having the inentum much broader, covering 

 the maxilla.'. 



Plattjgenia, Macl. (ba\'ing the l)ody very flat, the thorax sulicurdate, and the maxillce terminated by a pencil of 

 hulrs), anri 



Cremostoc/ieihix, Knocli (having the thorax transverse-quadrate, the niaxllK'e ternjinated by a strong tooth, 

 with small spines; composed of several small curious exotic species), have the mrntnm conca\e in the middle, and 

 the anterior extremity of the clyi)eus never cornuted nor toothed. 



Golialh, Lam., Kirby, has the mentum without any iliscoidal concavity, emarginate at the top edge, and the 

 anterior extremity of the clypeus of the males is dividt'd iiit(,i two lobes like truncated and obtuse horns. Tlie 

 tliorax is ncarh' orbicular. This genus is comi)Osed of large and splendid species, fi'om Africa and the Hast Indies. 

 Some species from South America have been separated by St. Fargeau and ServlUe under the name of hica, having 

 the fore femora armed with a tooth. All the known species are of large size, but one sent from the Cape of Good 

 Hope is not larger than C. gagates ; the fore thighs are not toothed in the Gollathi, and the tibiae have not a notch 

 in the inside. An insect from Java, considered as a Goliath by Serville and St. Fargeau, has all the characters of

 phijlhis, Weld. These splrndlil Insects lia\L' recently attracted conisiderable interest in this country, several of 

 the gigantic African species having been received by several Entomologists. Mr. Hope, in the ColeoplerisVs 

 Manmd ; Mr. Mac Leay, in his Memoir on the Cdoidhla ; Messrs. AYaterhouse and White, in the Mag. of Nat. 

 //(^/o/'j/, as well as myself in the new edition of Drury, have described various species, or distributed them into 

 subgenera. Various new species have also recently been described by the French Entomologists.^ 



Tlie third di\is,ioii of tlie "Melitophih, named CetoaiuJcs, [thus named, although riL-t corresponding 

 with tlie Cc/oniiihc of Mac Leay, as stated in the text,] has the sternum more or less prolonged into 

 an obtuse point between the second pair of legs ; the axillary piece is always visible above, occupying 

 the space between the posterior angles of the thorax and the shoulders of the elytra; the thorax ordi 

 narily triangular, but truncated in front ; the meutunr never transverse ; its front edge more or less 

 notched in the middle; the maxillary lobe is pencil-like; the body is nearly ovoid, and depressed. 



Gi/mnetis, Mac Leay, has tin' bind margin of the thorax pmduced o\ er the scutellum : the New World produces 

 several species. Others, frrnn Java and oilier parts of the East Indies, have tlie thorax elongated in the same 

 manner, but not entirely co\ering the scutellum, and the clyiieus is more or less bifid. Other species, from the 

 East Indies or New Holland, with tlie clypeus similarly bifid, or armed with two horns in the males, the abdomen 

 nearly triangular, and the ilnb of the anteniu'e very elongate, compose the genus Macronaia of Wiedemann ; but 



all these groups will possess no solidity until the numerous 

 species of the genus Ccfonia have been investigated. 



The European species possess a scutellum of the ordi- 

 nary siiC.
