May this not be explained on principle, of animal having come to island. where it could live — but there were causes to induce great change. like the Buzzard which has changed into Caracara at the Galapagos.

Waterhouse1 says he is certain, that in insects, each family, however many there may be, represent every other; for instance in Heteromera, you have representatives (which at first would be mistaken for) Carabidae, Crysomela, Scarabadae, & longicornes.— Again taking a subdivision of Heteromera

On p. 189:—"This collection consists chiefly of Coleopterous insects, and among them I had most of the curious formsobserved in the section Heteromera,—my object being to show that the species thus selected were analogous representations of other groups of beetles ; that is to say, that they departed from their own group in certain characters of form, colour, &c, and that in these respects they appear to have borrowed (if I may use such a term) the characters of other groups of the same order, to which they bear such a resemblance that they might at first sight be mistaken for species belonging to those groups".
