this reason al.s(i, I neglected to make the acquaintance of the Entomo- 

 logists at Berlin, which I now much regret." 



" After passing my examination, I returned to the Gymnasium at 

 Frankfort on the Oder, in 1830, and now began to devote all my leisure 

 time to Entomology and Botany ; for some years I rather neglected 

 Lepidoptcra for Coleoptera and Dipt era.''''* 



" In 1833, however, 1 made the acquaintance of Fischer-von- 

 Roslerstamm, and then returned with eagerness to the study of Lepid- 

 optera. I can, however, truly say, that if I have attained any correct 

 views, 1 do not owe them in any degree to the study of writers on the 

 Order Lepidoptera, but rather to the Coleopterologists, and above all 

 things to the Dipterologist, Meigen." 



As an instance of an early entry in Zeller's Journal may be given 

 the following, dated July 12, 1829. "In the early morning about 5 

 o'clock some very pretty moths were flying from fir-trees at Tegel (near 

 Berlin) ; of these I caught 2, one good and the other bad, the latter I 

 threw away." Many years afterwards the name of the insect was 

 added to this entry " (Ecophora Borkhausenii.'' 



The earliest printed notice of Zeller occurs, I believe, in Treitscbke's 

 " Schmetterlinge von Europa," IX, 2, p. 262, published in 1S33 ; he is 

 there described as " Herr Candidat Zeller in Frankfort an der Oder, a 

 zealous friend of Entomology," the notice refers to the rearing of a 

 number of Tinea tapezeUa from a decayed hoof of a horse. 



In the 3rd part of Treitscbke's 10th volume, published in 1835, Zeller 

 is three times mentioned, at pp. 141, 153 and 187 ; in the second of 

 these notices he is spoken of as " Herr Oberlehrer Zeller in Glogau," 

 showing that between 1833 and 1835 he had removed from Frankfort 

 on the Oder to Glogau, and had developed from a '" Candidat " to an 

 " Oberlehrer" 



Oken, the Editor of the "Isis," had offered a prize for the best 

 essay on the determination of the Lepidoptera which were noticed in 

 Eeaumur's " Memoires pour servir a I'histoire des insectes," and of the 

 two essays sent in to compete for this prize, the first prize was awarded 

 to P. C. Zeller, Oberlehrer an der evangel. Biirgerschule in Gross- 

 Glogau.f This " Kritische Bestimmung " extends to 112 columns (56 

 ])ages quarto), and revealed at once uncommon powers in the new 

 writer, who, thus in 1838, made his first appearance as an author. 



* Between 1840 and 1847, he published several Dipterological papers, and one on a Cole- 

 opterous subject, as may be seen in Hageii's Bibliotheca Entomologica. 



+ The second prize was awarded to C. F. Freyer of Augsburg, the illustrious author of the 

 " Beitriige" and " Neuere Beitnige."
