Classification of Insects: A Key to the Known Families of Insects and Other Terrestrial Arthropods

1,120 black-and-white drawings of insects. Moderate sunning to spine, elsewise a clean, tight, scholar/collector-worthy copy. A CLASSIC, IN-DEPTH, INVALUABLE RESOURCE! From the Introduction: "Approximately half a million species of insects have so far been described and named, and their number is being gradually increased from year to year. So far as those competent to judge are able to estimate, it seems probable that this number represents perhaps one-tenth or one-twentieth of those which actually exist upon our planet at the present time. Their descriptions fill libraries and their final identification requires the knowledge of specialists. Obviously no single volume can provide means for their complete determination, and attempts to deal with selected series of abundant species from particular regions are always disappointing and untrustworthy. It is possible to deal quite fully with the families into which the insects are divided within a reasonable space and it is with their recognition that the present work is concerned." Maroon cloth binding with gold gilt lettering on spine. 672 pages. *NOTE: Due to weight of book additional shipping may be required for out of U.S. shipment in conjunction with destination. FRB6.…
