PIERRE-ANDRE, an illustrious French naturalist, the "Prince of Entomologists," as he was called by the Comte Dejean, was born at Brives in 1762. He early gave evidence of a strong capacity, and it was resolved to educate him for the church. A kind friend placed him at the Collège Lemoine at Paris, where he remained for several years. During a subsequent visit to the capital, he found means to make himself known to the leading naturalists of the day, Fabricius, Olivier, Lamarck. In 1791, he became a correspondent of the Society of Natural History of Paris, and of the Linnean Society of London; and contributed many of the entomological articles to the Encyclopédie Methodique. When the Revolution broke out, he was still in orders, and was involved in the general fate of the priesthood; but the interest of his powerful friends saved him from ruin. The storm began to blow over, and in 1798 Latreille was employed to arrange the collection of insects in the museum. He was next appointed to assist Lamarck, when that distinguished naturalist was disabled by blindness. On his death, in 1829, Latreille was promoted to his chair. He did not long survive his predecessor, dying February 6, 1833, at the age of seventy. In 1814 he had been made a member of the Academy of Sciences, and seven years later a chevalier of the Legion of Honour. It has not been thought necessary here to describe his labours, which are analyzed at great length in the bibliographical part of the art. ENTOMOLOGY, vol. ix., p. 8. To Cuvier's Regne Animal Latreille contributed the whole of the Crustaceans, Arachnides, and Insects.
