The insects in Madeira which are not ground-feeders, and which, as certain flower-feeding coleoptera and lepidoptera, must habitually use their wings to gain their subsistence, have, as Mr. Wollaston suspects, their wings not at all reduced, but even enlarged.

马德拉的昆虫不是地面食动物， 而且像某些食的鞘目和鳞目昆虫，它们必须地使用它们的膀来维持生计， 正如沃拉斯顿先生所怀疑的那样， 它们的膀根本没有减少， 但甚至扩大。
