Probably one of the most-abused and most-discassed publication^ 

 chat have to be considered by those who have tackled the question of 

 the sjnonymy of the lepidoptera is Hübner's TentcDiwn. Possibly 

 this resulted frojn two causes : (1) Its rarity, so few copies beiiig 

 available for reference when synonymy began to be considered under 

 the present opposed niethods. (2) The difficulty of fixing the date of 

 its publication, which Seudder and others have since authorita- 

 tively settled was in 180C). Seudder, some years ago, reprinted the 

 Teoitainen from the copy in the Berlin Museum, we believe, and 

 Scudder's reprint is in general use for reference, but even this is so 

 rare, that workers at South Kensington are indebted to the courtesy 

 of Sir George Hampson for reference to abritten copy in his possession. 

 It was, therefore, witli niuch pleasure that I recently discovered, bound 

 at the end of a copy of vol. iv. of Ochfenbeimer and Treitschke's 

 Die Schmetterlinge von Europa, a set of wliich work I had purchased,. 

 an original copy of Hübner's Tentainen. Ojhsenheimer refers to the 

 publication of the Tentamen in his prefa,ce to this volume of Die 

 Schinett, von Europa, and, in the synonymic paragraphs, one tinds 

 unfailing reference to those species which Hübner has mentioned in 

 his publication. With the idea of showing our readers Hübner's views 

 of the Classification of the lepidoptera as set forth in the Tentamen, 

 we give a copy of the work, which, however, was issued as a quai'to 

 sheet. The columns are arranged exactly as in Hübner's paper.
