Book excerpt: Excerpt from Papers on Insects Affecting Stored Products: Contents and Index Lists of the insects that attack various cultivated crops are being published from time to time and republished with additional names until we have, of the various species that affect certain crops, some very complete lists. A notable example is the late Dr. J. A. Lintner's list of injurious apple-tree insects, which numbers 356 species. A preliminary list published by the same writer in 1882 contained only 176 species, less than half the number known to affect the apple 14 years later. Similar lists, more orless incomplete, but furnishing a basis for future additions, have been published of insects that affect the strawberry, the grapevine, the blackberry, the corn plant, the sugar beet, etc. Of many crops, however, there are no better pub lished lists than those given in the catalogue of the exhibits in eco nomic entomology at the World's Columbian Exposition issued in 1893 as Bulletin N o. 31 (old series) of this bureau and in other similar exhibition catalogues (bulletins 47, 48, and 53, new series) which have followed.
