When the fine fpecies of Libellula grandis was figured in plate 
166 of this work, we were not in poffeflion of the variety with 
yellow wings which Linnzus defcribes. It has fince been difcovered 
in the neighbourhood of Batterfea, and we deem it too interefting to 
be omitted. 
The yellow colour of the wings can by no means induce us to 
think it a diftin@ fpecies from the variety with wings perfeétly 
tranfparent, efpecially as the fame variation is obferved in moft other 
{pecies of the fame tribe, and particularly amongft the Englifh 
{pecies, as in flaveola, virgo, and puella. The-marks and colours 
of the abdomen and thorax are ftill more liable to variation, and cam 
{carcely furnifh any precife character for a {pecific difference.
