1912 188 p., 34 figures, 22 plates, original cloth.At a time when the White House, Senate, and Congress of America were concerned about insects. The letter of transmittal is, of course, signed by President Taft, the paper itself being the work of several entomologists, including L.O. Howard, entomologist and chief of bureau at the Department of Agriculture. This is the rarer first edition, not the more widely-available 1916 edition. A very good clean copy.
