confined to the south and south-west coast. Here it meets with the 

 range of C. solitaria, which is a true Papuan species. I have drawn 

 up a table which will exhibit at a glance the distribution of the 

 various species. In this table I have followed the usual arrangement 

 of Mr. Wallace of the various groups of islands : —

8. A Monographic Revision of the Lepidoptera hitherto in- 

 cluded in the Genus Adolias, with Descriptions of new 

 Genera and Species. By Arthur Gardiner Butler, 

 F.L.S., F.Z.S., &c. 



(Plate XLV.) 



The genus Adolias was monographed by Mr. Frederic Moore in 

 the year 1859, and again by Dr. Vollenhoven in 1862 ; but so much 

 has been learnt respecting the sexes and affinities of the species 

 since that time, the species themselves have increased to such an 

 extent, and the difficulty of classifying them has been so universally 

 felt, that a complete revision of the group has become a necessity. 



In the present paper I have been obliged to make several new 

 genera, on account of striking differences of structure observed ; the 

 species are also arranged in natural groups to facilitate their deter- 

 mination. 



The genus as it now stands contains sixty species, sixteen species 

 having been separated from it to constitute new genera, and eight 

 others being removed to the genus Si/mphcedra, Hiibner.
