534 NATURAL HISTORY. 
The grey Fie is not unlike the common Houfe-Flie, but not half fe 
Jarge: the eyes are reddith, the brealt grey, but marked with tw@ 
fmaller, and two larger black {pots: the body is greyifh, and coniilts 
of four joints; the firft of which is without fpots, but the fecond has 4 
three-toothed mark at its bafe, and the third and fourth has {pots nearly 
of the fame kind: this is a very common Flie. 
There are feveral torts of thefe infects, that are properly called Fliess 
which we thall range under feveral clafles. Of thofe that refemble the 
common Houfe-Flie, are, : 
1. The common houfe Fie/h-Flie with a black chequered body, and 
with oblong black ftreaks on the breatt. 
2. The black Fie with a white forehead. 
3. The black Fie with a fmooth glofly body. © 
4. The fmooth black Fie with iron grey eyes, and the bafe of the 
thighs whitifh: this Flie proceeds from maggots in cheefe. 
5, Uhe fmooth black #%e with the edges of the wings black, and 
thicker than the other part. 
6. The fomewhat hairy black F/%e with nervous wings. 
7. The grey Fie with fine black marks on the breaft, and three 
toothed {pots on the belly. 
8. ‘The yellow Fite with the belly brown on the upper part, and three 
‘lack ftreaks on the breatt. 
g. The yellow Fle with black eyes. 
Of the fhining or gilded Files there are, 
1. The Fike with a fhining blue breaft, and a fhining green body. 
2. The Fie with a thining green breaft, and a fhining blue body. 
3. The Fle with a black breaft and green body. 
4. The Flie with a black breaft and blue body. 
5- The Fle with an oblong body, of a copper-colour, and a green 
head, a yellow breaft, and the wings marked with a brown fpot. 
6. The oblong Fie with a brafly breaft, and the body yellow on the 
fore part, and black behind. 
It will not be improper to mention here the North American Flies 
there called the Fire-Flie, becaufe it appears like a {park of fire in the 
dark: they are as long as the Bees called Drones, but much thicker: 
and are of a brownith colour: the light proceeds from under the wings 
and they are a ftrange fight to new comers at firt. When their wings 
are broken, and they are placed on a book in a dark room, they fhin¢ 
fo much, that the letters near it may eafily be diftinguithed ; they ap- 
pear in May, and are vifible the eae part of the fummer; there 
are fometimes fuch a multitude of them in the woods, that they yield 
a very wonderful, and yet pleafing fight: they continue flying every 
hour in the night, but are never feen By day. 3 
The Fire-Flies of the Eaf-Jndies, are about an inch broad, and as 
much in length, or longer; the head which is brown, has two fmall 
horns or feelers, and the neck is red: they have four wings, and fo 
do not properly belong to this clafs, the uppermoft of which are hard 
and brown, and thofe underneath foft: the fhining fubftance is con- 
tained in a black bag on their backs, which they hide with their wings 
when they fit. In the rainy feafon there are prodigious fwarms 0 
them among the trees, and they feed chiefly upon their bloffoms+ 
there are feveral forts of thefe Flies in the Eaf-Indies, whe
