habituated to it from tbeir earliest boyhood, ai'e utterly unconscious), 

 and was at the same time very unwilling to have a breath of fresh 

 air admitted by an open window. 



In 1852 appeared also the 7th volume of tlie " Linnsea Entomo- 

 logica," in which Zeller treated of the genera Lypusa, Talasporia, 

 Solenohia, Diplodomn, and Xysmatodoma ; and in the same year he 

 also described Wahlberg's Caffrarian Micro-Lepidoptera in the Trans- 

 actions of the Stockholm Academy of Sciences. The following year 

 the genera Adela and Nemotois were treated monographically in the 

 8th volume of the " Linnsea," and a critical determination ox the species 

 figured by Clerck in his " Icones " appeared in the " Stettiner 

 entomologische Zeitung." 



In 1854, Zeller gave, in the 9th volume of the " Linnaea," the 

 genus Depressaria, and several allied genera (including 26 species of 

 the genus Cryptolechia) . The tenth volume of the " Linnsea," in 1855, 

 contained a postscript on Cryptolechia, with descriptions of 13 new 

 species, and also an elaborate Monograpb of tbe very difficult genus 

 Butalis. This was, we regret to say, the last of his masterly con- 

 tributions to the " Linnaea Entomologica." It was towards the end of 

 May, 1855, that the writer of these lines had the pleasure of seeing 

 Professor Zeller in his home at Gross-Glogau, and after spending two 

 days there, of meeting him for several days the guest of Dr. Dohrn at 

 Stettin and at Hokendorf. 



In 1855 appeared the first of the 13 volumes of the Natural 

 History of the Tineinn, by Staiutou, assisted by Zeller and Douglas ; 

 of this series the whole of the German and Latin letter-press was 

 translated by Professor Zeller from the original English, and he also 

 contributed many valuable remarks. 



At the end of March, 1860, Zeller left Gross-Glogau in Silesia, 

 where he had I'esided for a quarter of a century, for Meseritz, in Posen, 

 where he still continued his scholastic employment. Here, in 1863, 

 he wrote his Monograph of the Chilonidw and Cramhidce of 54 quarto 

 pages — this was printed as an Appendix to a " Schulnachricht," and 

 it is a very nice question, whether it was e^er published. The date on 

 the Monograph itself was not printed.* In 1865 a troublesome and 

 painful illness necessitated his absence from Meseritz for some weeks, 

 and he spent the greater part of June and July in that year at 

 Frauendorf, near Stettin. In May, 1S66, he retired from his school- 

 occupation, and had thenceforward more leisure to devote to Entomo-
