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 :- Tabular View of the Geographical Distribution of the Genus Ceyx. 1. C. rufidorsa 3.

A Monographic Revision of the Lepidoptera hitherto included in the Genus Adolias, with Descriptions of n ew Genera and Species. By A R T H U R G A R D I N E R B U T L E R, 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 determination. 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 Symphcedra, Hiibner. |
