Mr. Neumoegen and myself are at work upon this genus, with a view to present a revision of it; there are, however, some points upon which I should like to make a few independent remarks. The genus Halisidota is exclusively American, its stronghold being in the South. Indeed, the whole sub-family, the Phægopterinæ, are strongly, American, there being no European species and but few African, While still fewer reach through the East Indies to Australia.
