COLEOPTERA. 33 



Wiedemann, These sections however can only be considered as 

 established, when the numerous species of the genus Cetonia of 

 Fabricius have been particularly studied. 



Those of Europe are provided with a scutellum of an ordinary 

 size. Such are the 



C. aiirata; Scarabisus auratus, L. ; Oliv.^ Col., I, 6, i. i. 

 Nine lines in length ; a brilliant golden- green above, cupreous- 

 red beneath ; white spots on the elytra. Common on flowers 

 and frequently on those of the Rose and Elder. 



C. fastuosa. Fab.; Panz., Faun. Insect. Germ., XLI, 16. 

 Larger than the aurata ; immaculate, uniform, golden-green; 

 tarsi bluish. South of France. 



C.stictica; Scarab, s tic ticus,h.; Panz., lb., I, 4. Five lines 

 in length; black, somewhat pilose, with white points; those on 

 the venter arranged in two or three lines, according to the sex. 

 Very common on thistles *. 



In the second tribe of the Lamellicornes or the Lucanides, 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, 

 the first of which is usually much the longest. The mandibles are 

 always corneous, most commonly salient and larger, and even very 

 diff'erent in the males. The maxillae, in most of them, are terminated 

 by a narrow, elongated and silky lobe ; those of others are entirely 

 corneous and dentated. The ligula in the greater number is formed 

 of two small silky pencils projecting more or less beyond an almost 

 semi-circular or square mentum, The anterior legs are most fre- 

 quently elongated, and their tibise dentated along the whole of the 

 outer side. The tarsi terminate by two equal and simple hooks with 

 a little appendage terminated by two setae between them. The 

 elytra cover the whole of the abdomen above. 



We will divide it into two sections, corresponding to the genera 

 Lucanus and Passalus of Olivier. 



In the first Ave find the antennae strongly geniculate, glabrous or 

 but slightly pilose ; the labrum very small or confounded with the 

 epistoma ; maxillae terminated by a membranous or coriaceous, very 

 silky, penicilliform lobe without teeth, or at most with but one ; and 

 a ligula either entirely concealed or incorporated with the mentum, 

 or divided into two narrow, elongated, silky lobes, extending more or

 sect., T, iii, p. 126; Sclioenh. Synon., I, iii, p. 112, and Lin. Trans., XIV, with 

 respect to the genera, Genuchus, Schizorhina, and Gnathocera, established at the ex- 

 pence of that of Cetonia.
