392 INSECTA. 



TmcHius, Fab. 



T. nobilis. About an inch long; golden-gi-een above; cupreous with 

 yellowish-grey hairs beneath. On umbelliferous plants. 



The female of the T". Aemip^erus and those of some other species of North 

 America are remarkable for the horny ovipositor at the posterior ex- 

 tremity of their abdomen, by which they effect a lodgement for tlieir ova. 



These species are generally found on the ground, where they move very 

 slowly. There are two other genera, Platygenia and Cremasiocheilus. 



The second division, GoUathides, is distinguished from the preceding by 

 the mentum, which is much longer, wider, and covers the maxilla;. 



Goliath, Lam. Kirb. — Cetonia, Fab. Oliv. 



A subgenus which, according to M. de Lamarck, is composed of large 

 and beautiful species, some of which inhabit Africa and the East Indies, and 

 the others, tropical America. Messrs Lepeletier and Serville have separa- 

 ted the latter from it under the generic apptUation of IifCA. The epimera 

 is not prominent. The inner sides of the thighs of the two anterior legs are 

 furnished at base with a tooth and an emargination. The middle of the 

 superior mai-gin of the mentum is strongly emarginated; this part in the 

 true Goliaths presents four lobes or teeth, two superior and the two others 

 lateral. The labial palpi are inserted on its edges in the emarginations of 

 these latter lobes. All the known species are large. 



In the third division of the Melitophili, a section corresponding to the 

 family of the Cetoniidse, Mac Leay, the sternum is prolonged more or less 

 into an obtuse point between the second pair of legs; the epimera or axil- 

 lary piece is always apparent above, and occupies all the space that sepa- 

 rates the posterior angles of the thorax from the base of the elytra; the tho- 

 rax usually becomes widened posteriorly, and has the form of a triangle 

 truncated anteriorly or at the point. The mentum is never transversal, and 

 its superior edge is more or less emarginated in the middle. The terminal 

 lobe of the maxillje is silky or penicilliform. The body is almost ovoid, and 

 depressed. 



This division comprises the genus 



Cetonia, Fab., 



Or what we commonly term Goldbeaters. Those of Europe are pro- 

 vided with a scutellum of an ordinary size. Such are the 



C. aurata. Nine hues in length; brilliant golden-green above; cupreous- 

 red beneath; white spots on the elytra. Common on flowers, and frequently 

 on those of the Rose and Elder. 



In the second tribe of the Lamellicornes or the Ltjcanides, so 

 called from the genus Lucanus of Linnaeus, the antennal club is 

 composed of leaflets or teeth arranged perpendicularly to its axis in 

 the manner of a comb. These organs always consist of ten joints,
