have no systematist of note in this period. But recently the work, 

 written by Barbut in 1781, applying the Linnean method to English 

 insects has come somewhat into prominence. Whether it is worthy 

 of influencing synonymy must be left to those wiser than I, but 

 perhaps it is better to err on the side of inclusion rather than 

 exclusion. In France we have de Villers issuing an edition of 

 Linne's works with special reference to his own country. In Germany 

 we have the writings of Borkhausen, Scopoli, Hufnagel, etc., all 

 writing descriptions with observations more or less on the same 

 models, and seriatim, of European species known to them. 



Of observers the two most worthy of note are Geoffroy and Brahm. 

 The former's " History of Insects " in two quarto volumes issued in 

 Paris in 1762, contained matter much in the style of Reaumur. The 

 latter's "Kalendar" was, although never completed, an admirable 

 attempt to write a series of observations month by month to be of 

 use to all subsequent students. 



Turning now to the " picture " books, we get some most excellent 

 work, as well as a deal of secondary, although useful, delineation. 



Clerck, a Swedish artist and friend of Linne, in his "Pictures of 

 Rare Insects," was perhaps the first to make use of the Linnagan 

 system of nomenclature. This work was published at the instance 

 and expense of the Queen of Sweden, and I believe only a few 

 copies were issued. This was in 1759, the same year of issue as the 

 second part of Linne's " System of Nature." 



Drury was a Strand tradesman, who brought out three volumes of 

 plates with descriptive letterpress, mainly of Lepidoptera. They 

 contain illustrations of many species which, until recently, have been 

 rarely obtained since his time : 1 77 1 — 1782. 



One of the most valuable collections of plates of Lepidoptera was 

 published at Amsterdam from 1775 — 1 79° by Cramer. 



Esper and others brought out works with plates, mainly copied 

 from Cramer and Drury, and in turn they were copied by later 

 delineators, so that finally we get numbers of scarcely second-rate 

 books, in the main copied from those who themselves had copied 

 material that was not original. 



We must not forget that in this period the great Hiibner com- 

 menced his splendid contribution to entomological literature. Jacob 

 Hiibner was an artist, who for years devoted his leisure to the study 

 of the Lepidoptera, great and small. In his works we may say 

 everything was original. He did know his insects. He did appre- 

 ciate their relationship to the full. He did know where they fitted 

 in best in the natural order ; and he did know better than any man 

 ever has known how to picture them. No wonder his volumes of 

 hand-coloured plates fetch a long price at sales ; no wonder our 

 Entomological Society will not allow their precious volumes to be 

 taken from the Library. In all there are ten volumes, containing 

 over a thousand plates, with many figures on each, and it is scarcely 

 possible to mistake a single species, however minute, so great was
