XVI II. Monograph of the Australian Species o/Chrysomela, 

 Phyllocharis and allied Genera. By J. S. Baly, Esq. 



[Read November 6th, 1854.] 



Isolated descriptions of many insects belonging to the present 

 group are scattered through various Entomological works, both 

 abroad and in this country ; but hitherto no effort has been made 

 to collect and arrange them under the different genera to which 

 they properly belong : in the present paper I have attempted 

 this, at the same time giving descriptions of the many new species 

 existing in Collections. 



I must return my best thanks to all those gentlemen, who have 

 so liberally allowed me access to their Collections, placing in 

 my hands, for description, many unique and valuable insects.
