Genus CTJBICORHYNCHUS. Lacord. 



Antennae, breves. 



Ocull SLibovati subplani. 



Hostnim crassissimum quadratum planum e fronte sutura divisum, 



gula baud crassata. 

 Caput planum declinatum utrinque tuberculo parvo instructum. 

 Thorax subquadratus antice posticeque truncatus lateribus I'otun- 



datus apice trans versim impressus. 

 Elytra ovalia subdepi^essa postice verticalia. 

 Mamlibulce, pedes, ^"c, ut in Fsalidura. 



This is a very isolated genus, the nearest appi'oach to it being, 

 as I have just mentioned, the Acaidlioloplms planlcoUis of Water- 

 house. 



The leading characters are the minutely tuberculated flat 

 forehead, and flat square rostrum with transverse suture at its 

 base. I believe the species to be very numerous, but they 

 resemble one another so much that in the present paper I have 

 not ventured to do more than describe the most evident species. 



As regards their geographical distribution, I think that the 

 species are about equally divided between Western Australia, 

 South Australia, Victoria, and the inland parts of New South 

 Wales.
