black, with various yellowifh chara&ers; tail with three 
incurved claws. This is a large infeft, expanding four 
inches and a half. The nofe is yellow, having a black 
line on the prominent part; the thorax is black, with fe- 
veral broad yellow ftripes, two of which appear on the 
front, and two others between the ligaments of each pair 
of wings ; the abdomen is alfo black, having two ftreaks 
refembling a crefcent on each fegment ; the wings are 
tranfparent; and, but for a flight tinge of amber, almod 
white. 
48. Libellula grandis, the great dragon-fly : the larged 
of this genus found in Britain, and perhaps not inferior 
in bulk to any infe£t which this country produces. The 
fore-part of the head is yellow ; the eyes brown, and fa 
very large, that they meet upon the top of the head. See 
the Plate, fig. 15. The thoraxsis dun-coloured, with two 
oblique bands on each fide, of a lemon-colour. The ab¬ 
domen, which is very long, is likewife of a deep buff-co¬ 
lour, often fpotted with white upon the top and bottom 
of each fegment; the fmall appendages, which terminate 
the abdomen, are very long ; the wings have more or lefs 
of a yellow complexion, and are diftinguiflied by a brown 
fpot on the exterior edges. This infect makes its appear¬ 
ance principally towards the decline of fuminer, and is an 
animal of Angular beauty ; its general length is about 
three inches from head to tail ; and the wings, when ex¬ 
panded, meafure near four inches from tip to tip; the head 
is very large, and affixed to the thorax by an extremely 
flender neck ; the eyes occupy by far the greateft part of 
the head, and are of a pearly blue-grey calt, with a vary¬ 
ing luftre. In its motions it is extremely rapid, flying 
about in purfuit of its prey during the middle of the day, 
and is at this time taken with extreme difficulty, darting 
off on the flighted alarm from the fpot on which it had 
fettled, and in the fpace of a fecond or two flying to a 
vad didance. During the early morning hours, and thofis 
of evening, it is ealily taken ; at fuch times it is obferved 
to fit with its wings expanded, but in a perfectly inert 
date ; and will fuflfer itfelf to be readily feized by one of 
its wings, without attempting to dir from its place. 
49. Libellula variegata, the variegated dragon-fly: tho¬ 
rax with two yellow lines each fide ; wings with a white

men clavate, gibbous at the bafe; body variegated with

middle thinner and black with lateral yellow fpots, the 
tip thickened black, with a white tail. Inhabits China.

above and one beneath ; upper-wings black at the bafe 
with a yellow' fpot. Inhabits China. 
II. Wings ered when at rejl ; eyes diflincl ; outer divifions of 
the lip bifd. Agrion. 
52. Libellula virgo, the maiden dragon-fly. Thisbeau- 
•tiful libellula has a large head ; reticulated prominent red 
eyes that are not in contact with each other. The fpace 
intervening between the eyes, exhibits the three brown 
flemmata placed in triangle. The neck, on which tbs 
head is refted, is fliort and narrow. The thorax is larger, 
of a bright green or blue colour. From the inferior part 
of the thorax arife the fix legs, long and charged with a 
double row of fmall ipines, a circumdance common to 
this genus. From the upper part come forth the four 
wings, all of equal fize : they are much reticulated, and 
have on their middle a large cloud of a blnifh-brown that 
occupies above one half of them: the bafe and extremity 
of the wings are the only parts riot charged with the fame 
7 H colour.
