XXVI LIST OF AUTHORS 



complete work, which, for accuracy of description and 

 the magnificence of its plates, leaves little to be desired. 



HEYDEN, Carl von, Senator of Frankfort-on-Main, has pub- 

 lished " Entomologische Beitrage " and other papers in 

 the " Museum Senckenbergianum," a Zoological Miscel- 

 lany, put forth by the Senckenberg Soc. of Nat. Hist, at 

 Frankfort, of which von Heyden was Director ; and papers 

 in Oken's Isis and Silbermamr's Revue Entomologique. 

 Senator von Heyden is one of the first German entomo- 

 logists of the day ; his collection of minute insects of all 

 Orders is extremely rich ; and his Entomological Library 

 is one of the finest in existence : the results of his ob- 

 servations are recorded in all the recent works ; but it is 

 a cause for regret that we have so little from his own 

 pen. The possibility of the appearance of a " Frankfort 

 Fauna " has been hinted at ; and it is to be hoped that 

 such a work will soon see the light. 



HUBNER, Jakob, of Halle, an entomologist and artist of the 

 highest repute, author of " Beitrage zur Geschichte der 

 Schmetterlinge" (Augsburg, 1785-90), "Abbild. und 

 Beschreib. noch unbeschriebener und riicht abgebildeter 

 Schmett." (1785), " Sammlung Europ. Schmett." (com- 

 menced in 1805), " Geschichte Europ. Schmett." and 

 " Sammlung exotischer Schmett." (both commenced 

 in 1806), " Verzeichniss bekannter Schmett." (1826), 

 " Larvae Lepidopterorum," &c. His works have contri- 

 buted largely to the knowledge both of the species and 

 of the transformations of Lepidoptera, especially the Eu- 

 ropean ; his figures are generally full of truth, and, al- 

 though unaccompanied for the most part by descriptive 

 letter-press, have yet sufficed for the identification even 

 of the smallest species. The " Gesch. Europ. Schmett." 

 consists of 790 coloured quarto plates, each containing 

 figures of numerous species ; and the work on the trans- 

 formations of the European species consists of 449 co- 

 loured quarto plates. Hiibner died in 1827 ; and his 

 works have, f since his death, been continued by Geyer 

 and Herrich-Schaffer. 



HUFNAGEL wrote papers on insects in the " Berlinisches Ma- 

 gazin" (1782-85), and published in 1796, at Berlin, 

 " Tabellen von den Schmetterlingen der Berliner Ge- 

 gend." 



HUMMEL, A. Dav., author of " Essais Entomologiques " (St. 

 Petersburg, 1821-29), and of papers in Okeri's Isis, and 

 the " Mem. Nat. Moscou." 



ILLIGER, C., author of " Verzeichniss der Kafer Prcussens,
