Transcriber's Note

Changes to the text are limited to typographical errors, as listed at the end of the book.

Note that numerous taxonomic names have changed since 1894. The formatting of Latin names also differs from current conventions; e.g., in this book species names are typically, but not invariably, capitalised. No attempt has been made to update this.

The woodcut illustrations of adult insects from Figure 65 onwards have been prepared with thumbnails which preserve the same scale as the original book. The thumbnail illustrations should appear to scale when viewed on a monitor with 96 DPI, with a browser setting of 100%. Clicking on one of these thumbnail images or on the frontispiece will display a larger image.
