The first edition of this book having been nearly exhausted in less than a month after publication, the author has not yet had opportunity to avail himself of the criticisms of scientific friends who are presumably looking for sins of omission and commission, of which it is sincerely hoped they will acquaint him when discovered. Thus far all criticisms have been of an approbatory character, and have only expressed pleasure.

The writer is indebted to Mr. Harrison G. Dyar, the Honorary Curator of the Department of Entomology in the United States National Museum, for reminding him of the fact, which he had carelessly overlooked, that the larva and chrysalis of EumÆus atala (see p. 237) have been fully described by Scudder, "Memoirs of the Boston Society of Natural History," vol. ii., p. 413, and by Schwartz, "Insect Life," vol. i., p. 39. The caterpillar is found abundantly upon the "coontie" (Zamia integrifolia, Willdenow), and the insect, according to Schwartz, fairly swarms in the pine-woods between the shores of Biscayne Bay and the Everglades.
