" Fabricius described this insect from Sir Joseph Banks's cabinet, 

 as a species from the Cape of Good Hope. Olivier copied the error, 

 and figured one specimen, as obtained from the island of Bourbon. 

 Both writers are in error as to locality, as the insect is peculiar to 

 Java and the East Indian continent. Mr. Kirby has named the 

 above species in his collection E. Brightwellii, which I regard only as 

 a synonym of E. bicolor."

" This species I received from my late lamented friend General 

 Hardwicke, and for a long time I regarded it as the true bicolor of 

 Fabricius. Professor De Haan of Leyden has lately sent me E. bicolor. 

 Fab., from the island of Java ; I have therefore been obliged to name 

 an insect which I regarded as previously described. The species are 

 closely allied, and might have puzzled any individual. The concise 

 descriptions of Fabricius necessarily lead to error. It is of the 

 highest importance, then, to obtain authentic specimens from sources 

 which may be relied on, and I feel satisfied, that with regard to in- 

 sects, unless the few authentic cabinets known are carefully inspect- 

 ed, little reliance can be placed on specimens, without they are 

 named from comparison."

" This species, by the kindness of Dr. Horsfield, I have described 

 from the rich collection at the India House. It approaches in form 

 the genus Mimela, Kirby. It is remarkable for its opaline play of 

 colour, differing in that respect from all the species of my acquaint- 

 ance."
