NATURAL HISTORY 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 Lucanida? 
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 fig-)- 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.
