XV. On the species of Rutelidee inhabiting Eastern Asia 
and the Islands of the Malayan Archipelago. By

[Read 3rd May, 1875.] 
THE existence of species of animals or plants in parts of 
the world far removed from the geographical metropolis 
of the groups to which they respectively belong, is, at the 
present time, the subject of much interest in connection 
with the question of the diffusion of the different objects 
of creation on the earth’s surface. 
I therefore feel the less hesitation in calling the atten- 
tion of the Members of the Entomological Society to the 
beautiful family of Lamellicorn beetles Rutelide, which 
are for the most part natives of the South American Con- 
tinent, but of which certain species have been found in 
India and the Islands of the Eastern Archipelago; and 
the more so because the Transactions of the Society 
already contain descriptions of two of the most remark- 
able Eastern genera of this group, namely, Parastasia and 
Peperonota. Of the different sub-families into which the 
Rutelide have been divided, we find that the Macraspides, 
Pelidnotides, Chrysophorides, Geniatides and Rutelides, 
are entirely absent from the Old World. 
The Anoplognathides are exclusively and the Brachys- 
ternides partially natives of Australasia, the Australian 
genera Amblyterus and Schizognathus belonging to the 
latter sub-family. In the sub-family Chasmodiides, Phe- 
nomeris, illustrated from my drawings in the Transactions 
of the Zoological Society, is confined to South Africa and 
Madagascar. In the Areodides, Idiocnema sulcipennis of 
Falderman, Mem. Acad. St. Petersb. ii. p. 277, from 
Northern China, is the only Old World representative ; 
whilst, in the Adoretides, Trigonostoma mucoreum inhabits 
Madagascar, and the species of Adoretus are widely dis- 
tributed over Asia, Africa and the Eastern Islands.
