part it beats with is the extreme edge of the face, which may 
be called the upper lip, the mouth being protra61ed by this 
bony part, and lying underneath out of view 5 it was .^ of an 
inch long, the colour a dark brown, with fpots fomewhat 
lighter, irregularly placed^ which would not readily rub ofFj 
they feemed to lie rather athwart the. back, and directly on 
the head, as in Fig. 3. Plate IX. which is much of the fame 
fize with it, where the Macule are defigned for the greyifh 
Ipotsj under the Vaginae are pellucid wings, and the body 
is of a dark colour; the head appeared large, by reaibn of a 
large cap or helmet, which covered it round, only turned up 
a little at the ear, from under this appeared the head, which 
was flat and thin, the eyes forwards, the lip hard and ihining, 
the bars of the helmet greyifh 3 two Antennae proceeded fromi 
under the eyes, which by their meeting on the breaft, 
Mr. Allen conjeflured was to affift .their feeding, and were 
rather 'ProbofceSj and that the helmet was turned up for the 
fake of hearing, and the belly plicated like other beetles : The 
other beetle, that anfwered it, was iefs, and the marks on the 
back not {o diftinct: By the microfcope, he difcovered th^ 
marks to be fpots of hair thick fet, of a caftor colour ^ the 
head all hairy, and the face thick of curled hair; on the belly 
was a little hair, but thin fet; the eyes appeared large as in 
Fig. 4. the fuperficies confifting of many fmall fquares fur- 
rowed deep between, and thefe lay in lines defcending tranf- 
verfly towards the nofe; thefe eyes were not moveable, but 
contiguous to the face, without any cavity to receive them, and 
they were very opaque; the Antennae proceeded from under 
the eyes, the firft large joint having a cavity, out of which it 
proceeds at the fides of the lip; between the eyes, the face 
rifes in a little ridge, which is the nofe, and is fignified by the 
light part of the face ; and juil below it, the noitrils are co- 
vered by ftraight pendulous hair, proceeding from the lower 
ridge of the nofe; under this hair the cavity is dark, below 
the nofe, the lip-fhades fliew the more depreft places; under 
this lip are four vilible ForcipcSi two of each fide to lay hold 
on its food.
