Part of the original Pictured Key Nature Series. I have only seen the 1962 original paperback. There was a 1987 Dover reprint, apparently of the 1972 (2nd) edition.
Covers grasshoppers, termites, cockroaches, and mantids. Has 540 good black-and-white illustrations. Though somewhat dated, has more thorough coverage of some groups (e.g., Pygmy Grasshoppers, Tetrigidae) than more recent popular guides. Worth finding if you are interested in orthoptera.

The 1987 Dover reprint of the 2nd edition includes a new preface, new footnotes, new illustrations, treatment of crickets, and additions to the appendix, bibliography, and index (see discussion here).
