Auchenorrhynchous bugs (Hemiptera: Fulgoromorpha et Cicadomorpha) in the collection of the royal cartographer Karol de Perthées (1739–1815) and its importance for the knowledge of the fauna of Poland. The paper presents the results of the authors’ inventory of planthopper and leafhopper (former Auchenorrhyncha) species collected in the vicinity of Warsaw by the royal cartographer Karol de Perthées and described during his stay in Vilnius at the turn of 1802, on the basis of the drawings and descriptions included in his unpublished manuscript, entitled Volume I. In total, 38 species and 9 colour forms were identifed, of which 23 can be regarded as correctly named by Perthées. Most of the species represent suborder Cicadomorpha (33), and only 5 belong to suborder Fulgoromorpha. This is the frst documented historical information on the planthopper and leafhopper fauna of Poland. KEY WORDS: Fulgoromorpha, Cicadomorpha, Poland, historical records. INTRODUCTION Karol de Perthées was born in Dresden, in December 1739, into a family of French Hugenots, who had settled in Germany (buCzek 2003). At the age of 15 he was sent to a military academy in Berlin, and afterwards, in October 1763, having been recommended to Stanislaus August Poniatowski. Perthées started to work for the future king as a cartographer. After his coronation, King Stanislaus August appointed Karol Perthées as a royal cartographer and offered him a tied dwelling in Warsaw castle. Perthées’ main cartographic works were a map of the Kingdom of Poland and the Grand Duchy of Lithuania entitled Polonia secundum legitimas proiectionis stereographicae regulas (1770) and an Atlas of Poland (started in 1781) comprising maps presenting particular provinces. After the abdication and death of the King, Perthées moved with his family to Vilnius, where he undertook work for the Russian army as the Emperor’s geographer. Perthées passed on December 2, 1815 and was buried in the Calvinist cemetery in Vilnius (buCzek 2003, Pawłowski 2003a).
