Prof. RAPHAEL MELDOLA, F.R.S., F.C.S., in his Presidential Address to the Entomological Society of London, said:—“The authors of this volume are certainly to be congratulated upon having furnished such a valuable contribution to our literature. When its successor appears, and I will venture to express the hope that this will be at no very distant period, we shall be in possession of a treatise on the natural history of insects which, from the point of view of the general reader, will compare most favourably with any similar work that has been published in the English language.”
