40 PLATE CCCCVI. 
Geoffroy fpeaks of this fpecies of Dragon-fly as a rare infect in 
France, and we believe it to be very uncommon in England. The 
only fpecimen we have feen is one we poflefs in the cabiet of Mr. 
Drury, but from whence he obtained it we cannot afcertain. Ray 
appears to have defcribed this infe¢t as a native of Britain *. .

This fpecies bears fome refemblance to the female of Libellula 
Deprefia+, in fize and general appearance; but on the flighteft in- 
fpeétion will be found entirely diftinét. The abdomen is lefs deprefled 
on the back and narrower, and being befides fomewhat comprefled at 
the fides, affumes a much more linear form in the middle than Libellula 
Deprefia. The wings are totally different, and afford an excellent 
charaéteriftic by which the fpecies may be diftingnifhed. Each of thofe 
wings are marked on the anterior or coftal rib, with two fmall brown 
{pots, the one of which is fituated near the apex, as in moft of the tribe; 
the other about the middle on the anterior part of each wing: all the 
wings are yellowifh at the bafe, and in the pofterior pair, that part is 
diftinguifhed further by having a large brown fpot contiguous to the 
bedy.
