NATURAL HISTORY. 33 
the breaft is marked with five oblique furrows, and is large the head 
is almoft hid under the breaft, and the body grows narrower towards 
the tail. It does not appear tliat thefe two laft {pecies are dangerous 
to cattle. : 5 . 
The Virginian Burn-cow, is of a dutky braffy colour, with {pots on — 
the wings, and is of a pretty large fort: the head is almolt hid under 
the breaft, as in the former kinds, and the breaft is of a brafly colour, 
With a mixture of a reddith brown: the cafes of the wings are alfo of 
the fame colour; but not fo much of the red; but they are marked 
With four or five ftreaks, and on each there are two fpots; fo difpofed; 
as altogether to make a fquare figure when the cafes are clofed: they 
are of a bright and clear yellow. : 
Linnéus mentions the Bupreftis with a forked mouth, the greater water 
Bupreftis, and the leffler water Bupreftis. 
Water-beetles have generally feelers like briitles, and feet proper for 
fwimmings being a little bearded like an ear of corn, and are fix in 
humber, the hinder being a little longer and broader than thofe before : 
they never fly in the day time, but in the night, or at leaft very feldom. 
The great Water-beetle is an inch and halt long, and is all over of a 
deep, fomewhat gloffy black: the eyes are pretty large, the feelers 
- fhort, and the cafes of the wings fmooth on the furface, and under 
them there are wings, with a tincture of a filver colour: the body 
Brows {maller, and terminates almoft in a point behind it. Itis very 
€ommon in ponds and ditches, and feeds upon the fmaller water infedlss 
The black Water-beetle with the cafes of the wings that are yellow on 
the edges, is of the fame fize with the former ; but the head is fmall 
in proportion to the body : the eyes are large, and the legs ftrong and 
fobuft ; the edges of the cafes of the wings are very prominent, efpeci- 
ally about the middle, where they are of a yellow colour; but every 
Other part is black. It is common in rivets and brooks. 
- The goggle eyed Water-beeile is not quite fo large as the two pre- 
feding, but it has a big head, and the eyes are very prominent: the 
cafes of the wings are marked with ten ftreaks, which do not run through 
the whole length, for they are fmooth near the end: the ftreaks are 
Very deep, and the colour all over is of a blackith brown. 
_ The grey Water-deetle is not mtich bigger than the blue flefh-flie, and 
ts breaft is yellow in the middle, though black at the top and bottom : 
the cafes of the wings are of a greyifh colour; and are marked with a 
Sreat number of fhining {pecks of a yellowith colour, and at the edges 
ey are entirely yellow: there is alfo a yellow {pot in the thape of a 
eart, with black edges on the top: the point of the breaft is blunt, 
though a little forked. - 
_ Linnaeus takes notice of the Water-beetle with perfoliated feelers, of 
that with dilated fides, of the common Water-beetle, and of the Wa- 
ter-flea: thefe laft are remarkable for fkipping up and down upon the 
Water, as if they were at play; but when the water is troubled, they 
nk to the bottom, or hide themfelves in the holes of the banks. 
The osher fpecies ate the Water-beetle with a yellow breaft, that 
With brown wings and a black belly: the Water-beetle with a round 
Ody, marked with ten ftreaks on the cafes of the wings: the oval-bo- 
fied Water-beetle, with the aa of the wings and breaft black, but
