There is reason to believe that the genus Phanaeus, before the introduction of cattle, acted as scavengers to man. In Europe beetles which find support in the matter which has already contributed towards the life of other and larger animals, are so numerous that there must be considerably more than one hundred different species.

On the other hand, the horns are nearly as well developed in the female as in the male Phanaeus lancifer; and only a little less well developed in the females of some other species of this genus and of Copris. I am informed by Mr.
On the whole, as far as I could judge, the females of those Prionidae, in which the sexes differ, are coloured more richly than the males, and this does not accord with the common rule in regard to colour, when acquired through sexual selection.

On the banks of the Plata, where, from the vast number of cattle and horses, the fine plains of turf are richly manured, it is vain to seek the many kinds of dung-feeding beetles which occur so abundantly in Europe. On the opposite side of the Cordillera in Chiloe another species of Phanaeus is exceedingly abundant, and it buries the dung of the cattle in large earthen balls beneath the ground.
