In this year, too, J. J. Romer published his " Ge nera Insectorum Linntei et Fabncii, Iconibus trate, &c. Vitaduri Helvetiorum," 4to. This work contains thirty-seven explanatory plates, nearly all of which had previously constituted the work of Sulzer.
The celebrated Olivier published this year the first part of a very voluminous and valuable work, entitled, " Entomologie, ou Histoire Naturelle des Insectes, avec des caracteres generiques et speci fiques, &c. Paris.' 4W. From its title, it would seem that the author intended to have treated on every class and order; and, in conformity with the first part, to have illustrated the whole with figures. He, however, has confined the book entirely to the illustration of the Coleoptera, which was rendered as complete as possible, and as a work of reference, is one of very great utility.
G. Paykull produced in this year, at Upsal, " Monographia Staphylinorum Suecise," in octavo.
And C. de Villers published, at Lyons, a small work, under the title, " Linmei Entomologla, &c. curante et augeate C. de Villers, Lugduni," 8vo. In which the author has availed himself of the works of Scopoli, Geoffroy, De Geer, and Fabricius.
And at Leipsic, in Octavo, " Anfangsgriinde der Naturgeschichte von N. G. Leske." In 1790, some remarks on the genus Melolontha were published in the " Journal fur die Entomolo gie," &c. vor D. J. Mayer.

This author is also the author of two tracts, but we are ignorant of their dates; the first is on Papilio, entitled, " Beskrifningar ofer 8 nya Svenska, DaAarillar ;" the second on a moth, " Beskrifningar Ofer en y Nattjaril." G. Paykul too produced his " Monographia Cara borum Suecia." L. G. Scribe likewise published two works, " Bey trage an der Insecten Geschichte ; Frankfurt." And " Journal fiir die Liebhaber der Entomologie; Frankfurt." And " Insecten Kalender, von N. J. B. Mainz." 8vo.
The Journal de Rozier, Vol. XXXVI., contains a paper, entitled, " Notice sur un phenomene occasi. one par une espece de Fourmi nommee par Linnaeus • Formica nigra; par M. Dorthes." Lastly, the first volume of a great compilation on Zoology, entitled, " Vivarium Naturte, or the Natu.

Also, an interesting work on some Hymenoptera, entitled, " Naturgeschichte, Klassification und No menclatur der Insecten von Beinen, Wesgen und Ameisengeschlet. Frankfort am Main; von C. J. Ludwig." 4to.
In 1792, Edward Donovan published the first vo lume of his " Natural History of British Insects." 8vo. The work consists of eighteen volumes, which were published in successive years, and includes figures and descriptions of a considerable variety of species, being the most extensive elucidation of British Entomology that has hitherto been under taken.
