210 COLEOrilORID.E. 



The British species of the genus may be arranged in the fol- 

 lowing table : — 



a. Anterior wings brilliant metallic greenish, or bronze. Species 1-5. 

 a a. Anterior wings not greenish or bronze, and not unicolorous. 



h. Antennae much thickened with scales towards the base. Sp. 6-9. 

 h h. Autcnnte hardly thicl\ened with scales towards the base, or quite 

 bare. 

 c. Antennae with a tuft of hair at the basal joint. Species 10-17, 



and 20. 

 c c. Antenna} with no tuft of hair at the basal joint. Species 18, 

 19, 21-29. 

 n a a. Anterior wings not greenish or bronze, quite unicolorous, or only 

 with the costa slightly paler. Species 30-41. 



Many of the species are so extremely similar, and yet each 

 s])ccics has a considerable range of variation, that it is no easy 

 matter to decide from single specimens taken on tlie wing (and 

 frequently in rather wasted condition) to which species they should 

 be referred, or w liether they are not, in fact, new^ species ; to pro- 

 nounce with certainty on such points, we require to know the 

 larva?. It thus happens that many species I had previously cata- 

 logued as distinct, I have here united as synonyms of one s]Dccies ; 

 yet that I am correct in so doing can only be proved by the dis- 

 covery of the larva; being identical. Of some species, which I 

 have no doubt are distinct from any here enumerated, I possess 

 specimens, but in a condition too wasted to enable me to describe 

 them.
