40 PLATE CCCCVII. 



Geoffroy (peaks of this fpecies of Dragon-fly as a rare infe£fc in 

 France, and we believe it to be very uncommon in England. The 

 only fpecimen we have feen is one we poffefs in the cabinet of Mr. 

 Drury, but from whence he obtained it we cannot afcertain. Ray 

 appears to have defcribed this infe6i as a native of Britain *. 



This fpecies bears fome refemblance to the female of Libellula 

 Depreffaf, in fize and general appearance ; but on the flighted in- 

 fpe&ion will be found entirely diftincl. The abdomen is lefs depreffed 

 on the back and narrower, and being befides fomewhat compreffed at 

 the fides, affumes a much more linear form in the middle than Libellula 

 Depreffa. The wings are totally different, and afford an excellent 

 characteriftic by which the fpecies may be diftinguifned. Each of thofe 

 wings are marked on the anterior or coftal rib, with two fmall brown 

 fpots, the one of which is fituated near the apex, as in raoft 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 posterior pair, that part is 

 diftinguiihed further by having a large brown fpot / contiguous to the 

 bodv.
