Rh pleted by a locality-label at the bottom of the case, after the following model, which will explain to you our method.

My collections are divided into series:—1st. "The General Collection," to which the foregoing labels apply, and is arranged so as to exhibit seventy-five per cent. of the species actually described.

2nd. "The Belgian Collection," which contains the labels of all the species which may be met with in Belgium.

There is also a catalogue, followed by large maps of the country, and containing all the notes and descriptions which we have of our insects. There are about 14,000 cards.

3rd. The Congo Collection, in process of formation, and which I will refer to further on.

All these collections are found under three forms:—1st, The Collection; 2nd, Supplements; 3rd, Duplicates. All which we receive are immediately placed among the "Supplements," and when a sufficient number are obtained their study is commenced. Zool. 4th ser. vol. I., Feb. 1897.
