84 Mr. H. T. Stainton on the Recent Progress of 



which genus to place it, without any reference to the markings on 

 the wings. 



Some may remember, tliat Marginepunclella and Perlepidella 

 (then called FormoseUa) used to be placed side by side in the 

 same genus, and it was even questioned by some whether they 

 were specifically distinct; now by a reference to the smoothness 

 or roughness of the head, by the structure and clothing of the 

 palpi, it is at once seen that they belong to genera far apart. 



Naturally this paper of Zeller's produced the greatest effect in 

 Germany, where the serial work of Fischer Von Roslerstamm, 

 with coloured illustrations of the metamorphoses of many of the 

 Micro-Lepidoptera, appeared continuously from 1834 to 1843. 



But Professer Zeller was not content with having indicated the 

 arrangement and genera of the Tinece ; he proceeded to work up, 

 mouographically, the species in individual genera, and in 1846 

 appeared, in the first volume of the " Linnaea Entomologica," his 

 treatise on the genus Lithocoltelis ; and each succeeding volnie of 

 the "Linnaea" has contained papers by the same author on one 

 or more genera of Tincina, of which the following is a brief 

 enumeration : — 



1846. Vol, I. Lithncolletts. 



1847. Vol. II. Argyiesthia, Ociierostoma, Gracitaria, Coiiscium and Oriiix. 



1848. Vol. III. Lyonetla, Phijllocinslis, Ccmiostoma, Opostega, Buccniatrir, 



Nepticiila, Trifurcula and Tischeiia. 



1849. Vol. IV. Coleophora and Goniodoma. 



1851. Vol. V. Incurvaria, Mi'c»ojo(eri/x and Nemnphora, 



1852. Vol. \'I. Eiiplocumus, Tinea, Eviocotlis and Lampronia. 



1852. Vol. VII. Lypitsu, Talaporia, Sulenohia, Diplodiiina and Xysmatodoma, 



1853. Vol. VIII. Adela and Nemotois. 



1854. Vol. IX. Exceretia, Depressaria and Oriholaiia (with some exotic 



genera). 



1855. Vol. X. Butalis. 



But the very fact of there being such excellent Monographs 

 made the want of a good general work on the subject more pain- 

 fully felt ; and the Monographs published but a few years ago 

 are already quite obsolete, by no means representing the state of 

 our knowledge at the present day, so that the subject was seen in 

 a distorted point of view, only a small portion being as it were 

 in focus, and the rest more or less indistinct and misty. 



The group of Micro-Lepidoptera had been studied in Finland, 

 by Herr Tengstrou) and Dr. Nylander ; in Livonia, by Madame 

 Lienig; in Stettin, by Graf Nicelli ; in Breslaw, by Dr. Wocke ; 

 in Vienna, by Hcrrs Mann, Heeger, Lederer ; in Berlin, by Herr 

 Bouche ; in Jena, by Herr Schlager ; in Hanover, by Herr Kross-
