PHYTOPHAGOUS COLEOPTERA 



FROM AUSTRALIE AND THE MALAYAN REGIONS 



l>y llnrliii «lacoby. 



The présent paper deals with the material which I hâve received 

 from time to time from D" Staudinger, Mr. Fruhstorfer and others, 

 obtained at the Malayan islands and Australia; it comprises the 

 earlier groups Criocerinae, Eumolpinse and Halticinse; the Gale- 

 rucinae will form the subject of a future paper. The important 

 papers by Baly, those by myself founded on the large material 

 obtained by Sign. D'Alberti, Fea, Mr. Doherty and others will 

 enable the student to form a fair idea of the rich fauna of the islands 

 in question. The larger Malayan islands however as Bornéo, Java 

 and Sumatra hâve contributed by far the largest material, on the 

 other hand, according to Mr. Doherty, Ihe Phytophaga are but 

 sparingly represented south of the so called Wallace Une, while 

 New Guinea is only gradually becoming better known in regard to 

 its fauna.
