Lepidoptera. 



The first systematic arrangement of the Butterflies was 

 probably commenced by Mr. Edward Doubleday on his entry 

 into the service in 1842 ; these were catalogued by him in the 

 Lists published between 1844 and 1848. In 1851 Mr. G. R. 

 Gray revised the Papilionidse, publishing a catalogue of the 

 family in 1852 and a List in 1856. In 1864 Dr. A. G. Butler 

 began a complete rearrangement of the Butterflies, introducing 

 for the first time the Continental method of setting, as being in 

 every respect more satisfactory than that then in general use in 

 Great Britain. This rearrangement, owing to the small extent 

 of the collection at that date, occupied less than two years, but 

 the revision, expansion, and naming-up of various genera was 

 continued for several years later, the family Satyridse being 

 completely revised and catalogued in 1867. In 1890 the sub- 

 family Morpliinse was expanded and numerous accessions incor- 

 porated by Mr. F. A. Heron ; various genera of Nymphalinse 

 were also expanded and rearranged by the same gentleman. 

 In 1891 Mr. Heron commenced the rearrangement of the 

 Danainse, which had become greatly congested ; he also com- 

 menced the Hesperiadse in conjunction with Lieut. E. Y. Watson. 

 These groups were all completed in 1892. In 1893 the Euphsedra 

 group of Nymphaline Butterflies was revised and expanded, and 

 in 1894 the Amathusianse and Danainse of the Old World were 

 again arranged in order to incorporate the large series from 

 the Godman and Salvin collection ; the rearrangement of various 

 Nymphaline genera was also continued by Mr. Heron in this and 

 the succeeding years up to 1900. In 1895 he arranged the 

 Elymnianse, and Dr. Butler the Acrseinse. In 1896 Mr. Heron 

 arranged part of the Satyridse, and Dr. Butler commenced a 

 revision and rearrangement of the Pieridse, completing the sub- 

 family in 1898. In 1897 Mr. Heron commenced the arrangement 

 of the Ithomianse and Helieoninse, and in 1898 continued the 

 Satyridse, the genus Erehia being arranged by Mr. H. J. Elwes. 

 In 1899 Dr. Butler commenced a preliminary examination and 

 rearrangement of the Lycsenidse, which he completed in 1900 ; 

 Mr. Heron commenced a rearrangement of the Papilionidse, and 

 continued that of the Satyridse, Ithomianse and Nymphalinse. 



Between the beginning of 1902 and the end of 1904 the 

 Satyridse were completely rearranged by Mr. Elwes and Mr. 

 Heron. In 1904, while Mr. Elwes, who had previously (in 1899)
