to 1834; the first four being by Ochsenheimer, and the 

 remainder written by Treitschke after Ochsenheimcr's death. 



In 1820, Godart commenced his '• Papillons de France," a 

 work in octavo, of which he pubHshed five volumes, and the 

 book was continued by Duponchel. The work was completed 

 in eleven volumes, and four supplementary volumes, and 

 appeared from 1821 to 1842. The plates and descriptions 

 are good, and this still remains the standard French book on 

 Furopean Lcpidoptera. Godart's first plan was to limit himself 

 to the Lepidoptera of the neighbourhood of Paris, but the 

 scheme was soon extended to include those of France, and 

 ultimately of all Europe. 



Here we may notice some important works on European 

 Lcpidoptera which do not aim at completeness, but rather to 

 extend the knowledge of new or rare species aud their 

 transformations. 



Between 1828 and 1830, C. F. Freyer published three 

 httle volumes at Nuremberg, illustrating rare Lepidoptera under 

 the title of " Beitriige zur Geschichte europaischcr Schmetter- 

 linge, mit Abbildungen nach der Natur." This work was 

 followed by a more extended one, in seven volumes of a 

 larger size, published at Augsburg, from 1833 to 1858, under 

 the title of " Neuere Beitrage zur Schmetterlingskunde." 



In these works, new or rare species were described and 

 figured, but Fischer von Roslerstamm's "Abbildungen zur 

 Berichtigung und Erganzung der Schmetterlingskunde, 

 besonders der Microlepidopterologie," published at Leipzig 

 from 1834 to 1843, deals chiefly with the life-histories of the 

 smaller Moths. It is illustrated with 100 coloured plates. 



The great Diptcrist Meigen was likewise a Lepidopterist, 

 and published a work entitled '' Systematische Beschreibung 

 der Europaischen Schmetterlinge," which is less known than it 

 deserves to be, as the figures and descriptions are good. It
