De Geer also in this year, published the first volume of his invaluable work, Memoires puur servir a l'Histoire des Inseetes, at Stockholm, which was received with every demonstration of praise to which its merits are entitled.

In this year, a most valuable systematic work by Geoffroy, was published in Paris, and demands the at tention of the modern entomologist. It is entitled, His toire abregee des Insectes, and divides insects into six classes : 1. Coleopteres ; 2. Henzipteres ; 3. Tetra/acres rt ailes nues ; 4. Tetrapteres it ailcs farincuses ; 5. Dip teres ; and 6. .4fiteres. The first is ,.ne same with the Linnean order Co/eoptera; the second is regulated by the form of the proboscis ; the third agrees with the Lepidoptera ; the fourth comprehends the Neurofitera and Hymenoptera ; the fifth and sixth are the same with the Linnean orders Diptera and ?ptera. The charac ters of these orders are taken from the number of joints in the feet ; and the generic characters are taken from various parts of the body. Many of the genera are per fectly natural, and are still in use.
