XLVIII. Descriptions of New Phytopliaga. By J. S. 

 Baly, Esq. 



[Read 5th Oct., 1863.] 



The most striking amongst the insects described in the present 

 paper are two magnificent species ofjEsernia, a genus of true Chry- 

 somelidce; they were taken in New Guinea by Mr. Wallace, who has 

 brought home no less than five species of this beautiful genus from 

 that part of the world, three being new. In addition to several other 

 beautiful species, also collected by that gentleman, are some highly 

 interesting insects from Australia, sent home by Messrs. Diggles, 

 Waterhouse, and others ; amongst them a species of Plagiodera, 

 taken near Sydney by Mr. Lowne ; this is the first time, so far 

 as I am aware, that any species of the genus has been received 

 from any part of the Australian continent. Lastly, I must mention 

 a new Australica, taken in the interior of Australia by Mr. F. G. 

 Waterhouse.
