62 PLATE CCCCXV. 
Libellula ZEnea has been recently obferved in fwampy grounds in 
the neighbourhood of Hampftead. It is recorded as a Britith Enfeét 
by Ray; but fince his time appears to have become very fcarce 
till lately, when a {mall number of them were obferved in the above- 
mentioned fituation. We poflefs two varieties taken in this place, 
inthe fummer of 1805, which differ in fome flight particulars only, 
Both infects have the eyes of a brown colour, and the thorax of 
a brilliant green with a, brafiy luftre: the principal difference 
confifts in the colour of the wings, which i one fpecimen are hyaline, 
while on the contrary the wings of the other are tinged with 
teftaceous yellow. This-yellow-winged variety is further diftinguifhed 
by having the body gloffed with fine golden purple; in the other, the — 
body is of a brafiy green colour, with only a flight inclination to 
reddith brown*. Both infeéts are figured.m the annexed plate in 
their natural fize. 
This fpecies is not peculiar to England. Lineus deféribes it as a 
native of Sweden; from Geoffroy we learn, that it 1s a native of 
France; and from Roefel, as being found in Germany. 
* An indifferent figure of a fpecies of Libellula, much refembling this, occurs in the 
work of Schaeffer, Icon. Ratif. pl. 167, fig. 4, and which is probably intended for our 
yellow-winged variety.
