COLEOPTERA. 
527 
The Hoplides have the mandibles small, depressed, and apparently divided longitudinally into two 
parts ; the inner membranous and the outer horny. The extremity is not sensibly toothed ; the 
labrum is scarcely visible ; the maxillee 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. 
Hoplia, Illig., has but a single unguis to the hind tarsi ; those of the other feet are unequal and bifid ; the hind 
tibiae are terminated by a coronet of minute spines; the body squamose. {Hoplia argentea,Ol\\ . H. 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 ; tibiae short, with a strong curved spur. 
The fifth section, Anthobii, is composed of species closely allied to the Hoplides, but having the two 
I divisions of the lower lip produced considerably beyond the mentum, and the elytra gaping at the tips, 
I which are rounded ; the antennae have nine or ten joints ; the last three compose the club ; the ter- 
j 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 
j 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. 
Glaphyrus, 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, 
i and all the legs of ordinary size), have the basal joint of the club of the antennae concave, and inclosing the others, 
j Anthipna, Esch., has the club of the antennae composed of five leaflets. 
i 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. 
Chasmatopterus, Dej. (having all the tarsal ungues bifid), and 
Chasme, Lepel. & Serv. (having the larger unguis alone of the two posterior tarsi bifid), have the hind legs 
scarcely differing from the others, whilst in 
Diclieles, Lepel. & Serv., the hind feet, at least in the males, have the thighs very thick and toothed ; the tibiae 
I thick, and terminated by a strong claw. 
i Those which have but one unguis in the two posterior tarsi are Lepitrix, Lepel. and Serv., having nine joints in 
j! the antennae, and the terminal lobe of the maxillae very %\aid\\—Pachycnemus, Lepel. & Serv. (with 10-jointed 
j antennae, the maxillary lobe long and narrow, and the elytra narrowed behind), and Anisonyx, Latr., having the 
|! elytra oblong, rounded behind, with the hind tibiae subcylindric or elongate-conic. 
I The sixth and last section of the Scarahgeides {Melitophili) is composed of insects having the body 
,1 depressed, often of an oval form, brilliant, without horns, the thorax trapeziform or nearly orbicular ; 
ji an axillary piece occupies in the majority the space between the posterior angles of the thorax and 
ij 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 antennae have ten joints, the last 
three 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 
I 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 larvae live in old rotten wood : the 
i[ 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. 
I This section is divisible into three principal divisions, which correspond to the genera TricJiius, 
I Fabr. ; Goliathus, Lamarck ; and Cetonia, Fabr., in its restricted state. The Melitophili of the two first 
ij divisions have not the sternum much porrected, and the lateral or axillary piece of the mesosternum 
; {Epimera, Aud.) is not generally exposed above. Another character, which appears still more rigorous, 
|i consists in the labial palpi being inserted in lateral cavities on the anterior face of the mentum, the 
sides of the mentum extending behind them, and thus guarding them. 
The Trichides have the mentum either nearly isometrical, or longer than broad, with the maxilla 
I exposed. This division comprises the single subgenus 
1 Trichius, Fabr. [which has been cut up by Kirby, Gory, and others, into various minor subgenera]. Trichius 
' noMlis, Linn., and T. fasciatus, Linn, [are British species ; the latter exceedingly rare]. The female of T. hemi- 
; pterus, Linn., and some others from North America, are distinguished by having a long and slender horny instru-
