REVISION OF THE AUSTRALIAN CURCULIONID^ 

 BELONGING TO THE SUBFAMILY 



CR YPTORHYNCHIDES. 



Part VIIL 



By Arthur M. Lea. 

 (Continued from Proceedings, 1905^ 2).'258.) 



In this contribution and Parts 5, 6, and 7 of the revision, the 

 genera allied to Cryi)torhynchns are dealt with. These genera may 

 be regarded as forming several closely allied sections, Cryptorhyn- 

 chus and Tyrtceosus with several close allies forming one section; 

 Perissops and its many close allies forming another; Protopalus 

 with its allies forming a third, and this the most distinct section.* 

 Aonychus and Mecistocerus, although at a glance widely i^eparated 

 (and actually placed in different groups by M. Lacordaire), are 

 closely allied, on account of a supplementary prosternal process 

 (which appears to denote an approach to Camptorrhinus); with 

 them may be doubtfully placed Berosiris and Microherosiris; 

 Imalithus, Paratituacia and Sympediosoma lead off to and might 

 fairly be claimed as belonging to the ChcBtectetorus group; Nechyrus 

 might be regarded as belonging to the Poropterus group. 



In most of the species the clothing is not very dense; it is 

 often prettily variegated, and can usuall}^ be relied upon. Few 

 of the species are tuberculate, but many are granulate. Many of 

 the genera are very distinct and may be readily identified. The 

 rostrum is frequently long and thin, and is never straight. The 



* Protojyalus and its allies have been regarded as forming a very distinct 

 and isolated section, but there are several genera that clearly lead up to it 

 from Perissops.
