222 NATURAL HISTOET OF 



GYMNETIS MARMOREA. 



PLATE XVII. Fig. 6. 



Cetonia marmorea, Olivier, ii. pi. 2, fig. 110. 



The prevailing colour is fine yellow, the surface 

 polished and shining. The whole body is variegated 

 with black markings, arranged in a manner some- 

 what similar to those in the preceding species, but 

 having a greater tendency to run together and form 

 patches. The under parts of the body, and the legs, 

 are deep black and very glossy. It is a native of 

 Brazil. 



Having now illustrated at considerable length the 

 first tribe or principal division of the lamellicornes, 

 we shall proceed to give some examples of the se- 

 cond, which corresponds, as was already mentioned, 

 to the genus Lucanus of Linnaeus. The Lucanid^ 

 have ten-jointed antennae, the club or thickened 

 portion of which consists of long teeth or leaflets 

 arranged on an axis in the manner of a comb (Plate 

 XVIII. left-hand Jiff.). The mandibles are usually 

 of very large size in the male, and furnished with 

 strong teeth, which renders their appearance rather 

 more formidable than that of most other beetles. 

 The tarsi terminate in two simple claws, having 

 two strong bristles placed between them.
