The lapse of time and further observation on some of the things treated of in papers previously published in the Entomologist, render it desirable to make some corrections and additions.

Trogoderma ornata, Vol. XV., 91, and XVI., 37.— The treatment of this pest there detailed so completely annihilated it that it has not been seen since.

By frequent trips to the woods and marshes in spirng, to gather and sift the moss for hibernating coleopterta, by minutely examining the debris on the shore of Lake Erie, and by the use of umbrella and sweeping net later in the reason, I have added to my collection of beetles, since 1886, several hundred good species, The following list contains those of my captures that do not appear in the lists of Candadian Coleoptera.

It has long been a matter of fact to me, and one which has served a good purpose, and doubtless to other readers of the Can. Ent., that many butterflies, especially the larger kinds, are attracted by decoys resembling themselves in size and colour.

Amongst some fertile eggs of butterflies obtained during the past summer of gently pressing the abdomen of ripe females, was one of the above species, the larva of which was carried through four moults up to hibernation. The information gathered is incomplete; but as there is nothing published concerning the preparatory stages of C. Mandan, it seems worth recording, if only to assist others who may be fortunate enought to secure eggs of this rare butterfly. Although widely distribtued over North America, I know of no locality where it is abundant.

Of all the injuries committed year after year upon field and garden crops, none are more annoying than those due to the ravages of the various caterpillars known as Cut-worms. These are the larvæof dullcoloured, active moths, belonging for the most part of the three genera, Agrotis, Hadena, and Mamestra, and in North America alone constitute an army of no less than 340 different described species, many of which are, at times, very abundant.
