Rutela NitescenSy and Lamia Vnotata. 417 



From the bright colouring of the insect represented in the ac- 

 companying plate, I was induced to consider it a different species 

 from that figured by Olivier, and I was farther led into this 

 opinion in consequence of the bad representation of the structure 

 of the insect in his figure. I have lately however observed several 

 specimens in Mr. Such's Brazilian collection in which both the 

 bright and the dark colour is discernible : and I am informed by 

 that gentleman, that the living insect is invariably light coloured ; 

 that when allowed to die a natural death its elytra assume a 

 brownish or dusky tint, but when immediately killed after its 

 capture it retains its original brightness. I am indebted for a fine 

 series of this insect, as well as for many other valuable Brazilian 

 species, to the liberality of that gentleman, whose researches iu 

 the Brazils have added considerably to our resources both in 

 Ornithology and Entomology; and from whose zeal, and love of 

 science, we may expect much interesting information hereafter 

 from the same quarter.
