jnent at the extremity of the abdomen, with which they deposit their eggs. These species are commonly found 

 on the ground, where they crawl about slowly. [They form the subgenus Valgus of Scriba.] 



The second division, Goliathides, is distinguished by having the mentum much broader, covering 

 the maxillae. 



Platygenia, Macl. (having the body very fiat, the thorax subcordate, and the maxillae terminated by a pencil of 

 hairs), and 



Cremaslocheilus, Knoch (having the thorax transverse-quadrate, the maxillae terminated by a strong tooth, 

 with small spines ; composed of several small curious exotic species), have the mentum concave in the middle, and 

 the anterior extremity of the clypeus never cornuted nor toothed. 



Goliath, Lam., Kirby, has the mentum without any discoidal concavity, emarginate at the top edge, and the 

 anterior extremity of the clypeus of the males is divided into two lobes like truncated and obtuse horns. The 

 thorax is nearly orbicular. This genus is composed of large and splendid species, from Africa and the East Indies. 

 Some species from South America have been separated by St. Fargeau and Serville under the name of Iiica, 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 Goliathi, 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 

 Cetonia, only the thorax is rounder, and the male has a forked horn on the head. [This is the Goliath rhino- 

 phullus, Weid. These splendid insects have recently attracted considerable interest in this country, several of 

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

 Manual ; Mr. Mac Leay, in his Memoir on the Cctor.iitUe ; Messrs. Watcrhouse and White, in the Mag. of Nat. 

 History, 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.^ 



The third division of the Melitophili, named Cetoniides, [thus named, although nut corresponding 

 with the Cetoniid<e 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 mentum 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. 



Gymnetis, Mac Leay, has the hind margin of the thorax pioduced over the scutellum : the New World produces 

 several species. Others, from Java and other parts of the East Indies, have the thorax elongated in the same 

 manner, but not entirely covering the scutellum, and the clypeus is more or less bitid. Other species, from the 

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

 nearly triangular, and the club of the antenna; very elongate, compose the genus Macronata of Wiedemann ; but 



all these groups will possess no solidity until the numerous 

 species of the genus Cetonia have been investigated. 



The European species possess a scutellum of the ordi- 

 nary size. 



Cetonia atirata, Linn. — Nearly an inch long ; of a 

 shining-green colour above, coppery-red beneath, with 

 white marks on the elytra ; [is one of our commonest 

 insects, frequenting flowers, especially those of the 

 Rose, whence its common name, the Hose-beetle. It is 

 here figured with its larva, pupa, and cocoon, formed of 

 small particles of chips, &c] 



[The splendid Monographie des Cetoines by Messrs. 

 Gory and Percheron, although not sufficiently precise 

 either in its structural details or bibliographical refer- 

 ences, is indispensable to the student, as well as Mr. 

 Mac Leay's Memoir on the Cetoniida:, in Dr. Smith's 

 work on the African animals collected by him ; Mr. 

 Hope's Coleopterisfs Manual, and the general works on 

 insects recently published, must also be consulted for 

 descriptions of many new species, as well as genera, of 

 Lamellicorn Beetles. The larvae of this tribe have also 

 been admirably illustrated in an anatomical Memoir by 

 De Haan, published in the Memoires Nouvel'es du Mu- 

 seum d'llist. naturelle.] 



Fij, r . 71. — Cetonia aurnta. 



The second tribe of Lamellicorn Beetles, the 



Lucanides, — 

 So named after the Linnaean genus Lucanas, or Stag-beetles, has the club of the antenna? composed of 

 teeth arranged perpendicular to the axis, like a comh; they are always 10-jointed, the basal joint 

 bein 0, mostly very long, [the second being so inserted as to form an elbow with the preceding] ; the
