Présentation de l'éditeur
On p. 78, fig. 68 of the third edition has been replaced by a figure of A rthrolycosa antiqua Harger. On p. 258 correct figures of the larva and pupa of Melitcea Harrisii are given. The most important addition, however, is on p. 438, where a brief account of Le Conte snew family Platypsyllidce is given, and his figure of Platypsylla castoris Ritsema reproduced.

These are not of the usual palpus shape, but more or less rudimentary and modified in accordance with the peculiar mouth parts of these and allied insects. On p. 669, for lines 22, 23, read Macrobiotus Americanus JP ack. has been discovered by Rev. W. R. Cross in Maine. Some important changes have been made in the classification of the Coleoptera. The weevils, Curculionidce, should in accordance with the views expressed by Dr. Le Conte be placed at the end of the group. The Coccinellidce and Erotylidce should also in accordance with the views of Mr. G. R. Crotch (C heck List of the Coleoptera of America north of Mexico, 1874), be placed in the Clavicorn series, those and allied families being placed in the following succession: Dermestidce, JE ndomychidce, Cioidce, Erotylidce, A tomariidce, Cucujidce, Colydiidce, Rhizophagidce, Trogositidce, Nitidulidce, Coccinellidce, Cistelidce,
