M. Emery ayant revise la synonymie du groupe, il vaut autant remonter tout en haut. Le C. thoracicus etant de Bar- barie et correspondant au groupe oasium , dichrous , etc, qui vit dans ce pays, tandis que le maculatus i. sp. ne s'y trouve pas, c'est le nom de Fabricius que doit prendre la race dont fellah , dichrous , oasium , etc, seront les varietes. J'ai confondu autrefois l' oasium et le dichrous , comme le dit M. Emery.
