Of the more general works, some may be obtained direct from the publishers, and in such cases the publishers are mentioned in the general list. The older works are mostly out of print and can only be obtained from second-hand dealers. The current State reports of Lintner and Forbes may be obtained from the secretaries of the respective State agricultural societies at Albany, N. Y., and Springfield, Ill., while the bulletins and reports of the entomologists of the various State experiment stations, of which a large number are being published, may be obtained from the directors of the respective stations. The older reports of the State entomologist of Missouri and the State entomologists of Illinois (Walsh, Le Baron, and Thomas) are all out of print and can only be obtained by purchase from second-hand dealers. The same may be said of the well-known and oft-quoted reports of Dr. Fitch, which were published with the old volumes of the Transactions of the New York State Agricultural Society. * * * * * The table below lists all corrections applied to the original text. p iii: Detailed instructions for breeding -> rearing p 5: Spiders, and Myriopods -> Myriapods p 5: comprising Spiders, Myriopods -> Myriapods p 7: If we endevor -> endeavor p 8: of the Sub-orders-> Suborders p 9: Springtails -> Spring-tails p 9: Plectoptera -> Plecoptera p 14: the case of the Horntails -> Horn-tails p 14: FIG. 8.--Sawfly -> Saw-fly p 14: Beetles or-> duplicate "or" deleted p 16: of the common silk-worm -> silkworm p 16: variety of these larvae -> larvae p 17: structure of the antennae -> antennae p 17: HETEROPTERA ([Greek: heteros], -> comma added p 17: looked upon as a Sub-order -> Suborder p 17: A Plant-bug Euschistes -> Euschistus p 18: DIMERA, with two joints; -> comma changed to semicolon p 19: four or five joints. -> period added p 20: hatched in the abodmen -> abdomen p 21: A Locust Acrideum -> Acridium p 21: Orthoptera -> changed from smallcaps to all capital letters p 21: Tree-cricket Ocharis -> Orocharis p 21: Phyllodromia germanica.) -> germanica). p 22: "Earwigs, consisting -> Earwigs p 26: A May-fly Protamanthus -> Potamanthus p 28: (Fig. c) -> (Fig. 45, c) p 30: frequently have occassion -> occasion p 47: put in the seive -> sieve p 51: butterflies, whose larvae -> larvae p 51: as their mouthparts -> mouth-parts p 53: and otherwiise dsposed -> otherwise disposed p 54: animals.
