Volume Vi.

HYMENOPTERA continued (TUBULIFERA AND ACULEATA), COLEOPTERA, STREPSIPTERA, LEPIDOPTERA, DIPTERA, APHANIPTERA, THYSANOPTERA, HEMIPTERA, ANOPLURA. By DAVID SHARP, M.A., F.R.S.

SATURDAY REVIEW.—"Dr. Sharp's treatment is altogether worthy of the series and of his own high scientific reputation. But in a work of this sort it is not only necessary that information should be accurate, but also that it shall be presented to the eye, so far as illustrations and printing are concerned, in such a way as to render its matter as easily intelligible as possible, and readily usable for purposes of reference. Under both these heads we have nothing but commendation for Mr. Sharp's treatise. The illustrations are indeed beautiful, and the use of the heavy type for the headings of the various sections and leading paragraphs materially helps the reader in the progress of his study. Certainly this is a book that should be in every entomologist's library."

DAILY NEWS.—"It would be hard to say too much in praise of this most admirable volume. It is too often the case that scientific books are written in a dull and uninteresting style. The reader will find nothing of that kind to complain of here. The descriptions are clear, the illustrations are excellent; while, as in the previous volumes of the series, printing and paper are all that could be desired."
