EIBLIOGRAPHY. 1 67 



Most of the volumes of this series are very carefully written, and 

 those of Guenee will be referred to again in our vol. v. (see also 

 a7iied p. xxx.). They were, however, extravagantly over-esti- 

 mated in England for some years after their publication. 



Two volumes of Chenu's"Encyclopedied'HistoireNaturelle" 

 relate to Lepidoptera (Papillons), and were published about 

 1857. They are very cheap, and are illustrated with a great 

 number of excellent woodcuts. The first volume, which con- 

 tains Butterflies, Castnides^ Sphinges, &c., is by far the most 

 valuable, not only because it is more accurate and better written 

 than the second, but because it is largely based upon Double- 

 day, Hewitson, and Westwood's " Genera of Diurnal Lepidop- 

 fci'a,'' always a costly book, of which we shall speak later on. 



In 1 850-1858, Herrich-Schiiffer published a valuable series 

 of coloured plates of Exotic Lepidoptera, under the title of 

 *' Sammlung neuer oder wenig bekannter aussereuropaischer 

 Schmetterlinge," and in 1869 he published the first part of a pro- 

 posed second volume, which he did not live to continue. The 

 complete volume does not include descriptions, but lists of 

 species, characters of genera, and a revised system of 

 Lepidoptera. (Cf. antea, p. xxx.) 



Lepidoptera generally form a more or less important part of 

 the reports of scientific voyages and expeditions, but most of 

 these sink into insignificance before the magnificent series 

 of five volumes of quarto plates forming the lepidopterous sec- 

 tion illustrating the Voyage of the Novara (Reise der Oster- 

 reichischen Fregatte Novara um die Erde). This voyage, how- 

 ever, fruitful as it was of scientific results, mainly served as an 

 opportunity to Dr. Cajetan Felder, the Burgomaster of Vienna, 

 to make known to the world the many rare and beautiful species 

 contained in the public and private collections of Vienna. 

 The whole series of plates amounts to 139. Three volumes of 

 RJiopalocera were published by Dr. Felder and his son, Rudolf
