COLEOPTERA. 52/ 



The IlopUdes have the mandibles small, dcpi esses], and apparently divided longitudinally into two 

 parts; the inner membranous and the outer horny. The extremity is not sensibly toothed; the 

 labium is scarcely visible ; the maxillae have rarely only minute teeth ; the two hind tarsi have gene- 

 rally only one claw. 



Dicrania, Lepel. & Serv., have two ungues, alike, and bifid in all the tarsi; body polished; species inhabiting 

 Brazil. 



IJoplia, Illig., has but a single unguis to the hind tarsi ; those of the other feet are unequal and bifid ; the hand 

 tibia; are terminated by a coronet of minute spines; the body squamose. [Hoplia argentea,0\\x. II. pulveru- 

 lenta is the only British species.] 



Monocheles, Illig., differs from Hoplia in the clypeus being in form of a triangle, truncated in front ; thighs of 

 hind legs very robust ; tibia' short, witli a strong curved spur. 



The fifth section, Anthobii, is composed of species closely allied to the IlopUdes, but having the two 

 divisions of the lower lip produced considerably beyond the mentum, and the elytra gaping at the tips, 

 which are rounded ; the antennae have nine or ten joints ; the last three compose the club ; the ter- 

 minal lobe of the maxillae is membranous, silky, and pencil-like, but leathery in others; the upper lip 

 and mandibles are more or less solid as they are more or less exposed. These insects live upon 

 flowers or leaves. [None of these insects are found in England ; they chiefly inhabit the southern 

 parts of Europe and the warm parts of both hemispheres.] 



Some have the labrum and mandibles exserted, and two equal and entire claws in all the tarsi. 



Glaphyrut, Latr. (having the inner edge of the mandibles toothed, the club of the antennae ovoid, and the hind 

 legs large), and 



Amphicoma, Latr. (having the mandibles without teeth on the inner edge, and the club of the antennae globular, 

 and all the legs of ordinary size), have the basal joint of the club of the antennae concave, and inclosing the others. 



Anthipna, l'.sch., has the club of the antenna; composed of five leaflets. 



The others have the labrum and mandibles covered or not exserted, and some at least of the ungues of the tarsi 

 are bifid, and in some of these all the tarsi have two ungues. 



Chatmatopterus, Dej. (having all the tarsal ungues bifid), and 



C/iasmc, Lepel. & Serv. (having the larger unguis alone of the two posterior tarsi bifid), have the hind legs 

 scarcely differing from the others, whilst in 



Dichelet, Lepel. & Serv., the hind feet, at least in the males, have the thighs very thick and toothed ; the tibiae 

 thick, and terminated by a strong claw. 



Those which have but one unguis in the two posterior tarsi are Lepitri.r, Lepel. and Serv., having nine joints in 

 the antennae, and the terminal lobe of the maxilla' very small — Pachycnemus, Lepel. & Serv. (with 10-jointed 

 antennae, the maxillary lobe long and narrow, and the elytra narrowed behind), and Anisonyx, Latr., having the 

 elytra oblong, rounded behind, with the hind tibia; subcylindric or elongate-conic. 



The sixth and last section of the Scarabaeidcs (Melilop/iili) is composed of insects having the body 

 depressed, often of an oval form, brilliant, without horns, the thorax trapcziform or nearly orbicular; 

 an axillary piece occupies in the majority the space between the posterior angles of the thorax and 

 the shoulders of the elytra ; the anus is not covered ; the sternum is often prolonged into a point or 

 advanced horn ; the claws of the tarsi are equal and simple ; the antenna' have ten joints, the last 

 thrt;c of which form the club, always leafed. The labrum and mandibles are concealed, and in the 

 form of flattened plates, entirely or partly membranous; the maxillae are terminated by a hairy lobe 

 like a brush, without horny teeth ; the mentum is ordinarily ovoid, truncated above or nearly square, 

 with the middle of the upper edge more or less concave. The larva- live in old rotten wood : the 

 perfect insect is found upon flowers, as well as on the trunks of trees, in places where the sap 

 exudes, and which they greedily lap up. 



This section is divisible into three principal divisions, which correspond to the genera Trickhu, 

 Fabr. ; GoHathtu, Lamarck ; and Cetonia, Fabr., in it •- restricted state. The Metitophili of" the two 6rat 

 divisions have not the sternum much porrected, and the lateral or axillary piece of the mesOBternum 

 (Epimera, Aiul.'i is not generally exposed above. Another character, which appears still more rigorous, 

 consists in the labial palpi being inserted in lateral ca\itics on the anterior face of the mentum, the 



sides of the mentum extending behind them, and thus guarding them, 



The Trichides have tin- mentum either neatly isometrical, or longer than broad, with the maxilhu 



exposed. This division comprises the single subgenus 



Trichiut, Fabr. [which has been cut op by Kirby, Gory, and others, into varions minor subgenera]. TrieUtH 

 Hobilis, Linn., and T./tueiatut, Linn, 'are British Bpeciea j the latter exceedingly rare]. 'I be ft male of /'. /-• wtU
