210 COLEOPHORID A. 
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. 
aa. Anterior wings not greenish or bronze, and not unicolorous. 
4. Antenne much thickened with scales towards the base. Sp. 6-9, 
é b. Antenne hardly thickened with scales towards the base, or quite 
bare. 
c. Antenne with a tuft of hair at the basal joint. Species 10-17, 
and 20. : 
ec. Antenne with no tuft of hair at the basal joint. Species 18, 
19, 21-29. 
aaa. 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 
species has a considerable range of variation, that it is no easy 
matter to decide from single specimens taken on the wing (and 
frequently in rather wasted condition) to which species they should 
be referred, or whether they are not, in fact, new species; to pro- 
nounce with certainty on such points, we require to know the 
larve. It thus happens that many species I had previously cata- 
logued as distinct, I have here united as synonyms of one species ; 
yet that I am correct in so doing can only be proved by the dis- 
covery of the larvae 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.
