When the fine fpecies of Libellula grandis was figured in plate 

 166 of this work, we were not in ponTelHon of the variety with 

 yellow wings v/hich Linnasus 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<5l fpecies from the variety with wings perfedly 

 tranfparent, efpecially as the fame variation is obferved in mod other 

 fpecies of the fame tribe, and particularly ainongft the Englifli 

 fpecies in flaveola virgo and puella. The marks and colours of 

 the abdomen and thorax are ftill more liable to variation, and can 

 fcarcely furnifh any precife character for a fpecific difference.
