Berlin, Laspeyres, 1801; Hof, Gottfried Adolph Grau, 1798; Erlangen, Wolfgang Walthers, 1778. Three papers in one. 4to (24.5 x 19.1 cm). Laspeyres: Half-title, title with seven fine entomological engravings (each numbered), 32 pp.; one finely engraved and hand-coloured plate (tissue-guarded). Jördens: original green pictorial wrappers; title page, [i], 46, [ii] pp.; one finely engraved and hand-coloured plate. Esper: title page with engraved vignette, 20 pp.; one finely hand-coloured engraved plate. Fine contemporary full calf with elaborate gilt empire-style spine and board edges, and marbled wrappers. = Three rare works on Lepidoptera. Johann Jördens probably designed the two peculiar, nicely illustrated wrappers himself. On the verso of the first blank page "Ein Missverständniss" is stated, as the tree is a "Föhrenbaum" instead of a "Fichte". Also included are two other entomological publications, namely Laspeyres' fine monograph on Sesiidae, and Esper's work on a new Bombyx. All three are rare, and in fine copies. Jördens' work neither in Nissen nor in Cat. BM(NH). Horn-Schenkling, 6093 (Esper), 11274 (Joerdens), 12789 (Laspeyres).
