VIII. — On a few new Bornean Beetles of the Rutelid Genera 

 Mimela and Anomala. By Gilbert J. Arrow. 



(Published by permission of the Trustees of the British Museum.) 



The British Museum collection contains a very considerable 

 number of species of the great genus Anomala from Borneo, 

 few of which have at present been described. Some of the 

 more interesting forms are here characterized and two species 

 of the closely related genus Mimela are added. The group of 

 species at the end of thi3 paper form a new section of 

 Anomala, distinguished by a sexual difference in the pygidium, 

 of a kind hitherto unknown.
