lu 1847 there appeared in the " Isis " his "Remarks on the 

 Lepidoptera collected during a journey in Italy and Sicily" (the 

 journey in 1844< to which we have already alluded), and the same year 

 there appeared in the " Linnaea Entomologica, " vol. 2, his treatise 

 on Argyresthia. 



In 1848 there appeared in the "Isis" his treatises: 1st, on the 

 Galleries and naked-horned Phycidce, and 2nd, on the exotic Phycidce, 

 and in the third volume of the " Linnaea Entomologica" his Monograph 

 of "the Genera of leaf-mining Tineidce with Eye-caps" (^Lyonetia, 

 Opostega, JSucculatrix, Nepticula, &c.). 



Unfortunately, 1848 was the year of Continental Kevolutious, 

 and partly owing to the political disquiet of the time the " Isis von 

 Oken " (commenced in 1817) thenceforward ceased to appear. For 

 all naturalists, the discontinuance of this valuable miscellany was a 

 great deprivation, but to Entomologists in particular, who had seen 

 its pages of late years so largely filled with the writings of P. C. Zellei', 

 the loss was immense. 



In 1849, Zeller produced, in the 4th volume of the " Linnaea 

 Entomologica," a treatise of more than 200 pages on Coleophora ; and 

 in that and the following year he gave, in the pages of the " Stettiner 

 entomologische Zeitung, " an elaborate notice of the Lepidoptera 

 collected by Herr Joseph Mann in Tuscany, in 1846. 



In 1851 appeared, in the 5th volume of the Linna?a, a treatise 

 on the three genera, Incurvaria, Micropteryx, and Nemophora, and in the 

 following year, in vol. 6 of the same work, was a Monograph of the 

 other Tineidce with long maxillary palpi {Euplocamus, Tinea, LJriocoftis, 

 and Lampronid), and also a revision of the Pterophoridce. 



In 1852 it was that Zeller, who had lately received from the 

 King of Prussia a special award of the title of Professor, visited 

 England in company with his friend. Dr. C. A. Dohrn of Stettin. 

 This visit occurred in the month of July and only lasted a fortnight, 

 but during that period he visited four Entomological localities : 

 Charlton sand-pit. West Wickham "Wood,Mickleham and Sanderstead ;" 

 he also visited Professor Westwood at Hammersmith, and Henry 

 Doubleday at Epping. It is, however, to be feared that this visit was 

 not one of pure enjoyment, as the worthy Professor's stomach had 

 been more or less disarranged by the transit from Ostend to Dover, 

 and the "sentiment of the water," as he expressed it, still remained 

 with him the greater part of his visit, besides, he had a great aversion 

 to the smell of campho* (a perfume of which English Entomologists,
