~ hid by the faid projection, which ferves as 
an eyelid, and moves backwards and for- 
forwards over the eye, as the Beetle moves 
its head.

d The nofe-horn of the fkull, refembling the 
probofcis of an Elephant. 
e Atubercle, in form of a tooth, growing near © 
the end of the nofe-horn, which is more- 
over cleft in the middle; butas this is a fide 
view of the infect, the faid cleft cannot be 
feen. 
f The breaft bone. 
gg Two fharp prominent forks, or teeth of 
the breaft-bone, in regard to which I con- 
fider this infect as having fome refemblance 
to an Elephant. . 
b The lids that cover the wings. 
i The fecond joint of the legs. 
k The third joint. ach 
1 The fourth joint, or the foot, with its joints, 
hairs and nails. 
As all thefe parts are compofed of a folid horny 
bone, the mufcles are enclofed by them, 
whereas on the contrary in men and quad- 
rupedes, the bones lie within the flefh. This 
Beetle is very black, but fhining withall, 
like polifhed ebony, fo as to afford a very 
pleafing fpectacle, efpecially as its colour 
has a reddith caft.

dd The breaft-bone, and its projeCtons. 
ee The fheaths of the wings. All the paits 
are gray, owing to an infinite number of 
{mall hairs, that grow on them, the nofe- 
horn, and projections of the breaft-bone ex- 
cepted: But the ground of the horny bone, 
on which thefe hairs grow, is black, as is 
likewife the horny bone of the foot, whofe 
hairs do not grow fo clofe, as thofe covering 
the other parts.

Lower down, and more forward than the

a horny bone, which are covered with loofé 
hairs.
