and Colonel Sykes. Lamia reticulator of Fabricius, which is remarkable for its 

 penicillated antennae and tiuncate elytra, appears decidedly to belong to an- 

 other genus not yet characterized.

This magnificent insect I have named in honour of the President of the 

 Linnean Society. It is almost impossible to convey by description an idea of 

 the beauty of this species. Its external appearance is of a light beryl colour : 

 when examined under the lens, it lias tiie appearance of mother-of-pearl, and 

 closely resembles the feathery scales of the Lepidoptera. 



The nature and causes of the colouring matter of insects is very imperfectly 

 understood.
