DRAGON-FLIES, ETC. 225 



Some of the exotic species of Chrysopahave larger 

 wings than our native kinds, hut are not more 

 richly coloured. A species from the Amazon River, 

 remarkable for the size of its beautiful wings, has 

 been named by the eminent Continental entomo- 

 logist, M. Guerin, Chrysopa Marionella, after the 

 daughter of my esteemed friend, Mr. Adam White, 

 of the entomological department of the British Mu- 

 seum, to whose knowledge and experience I have 

 been much indebted, not only during the prepara- 

 tion of this unpretending volume, but on many 

 other occasions.
