190 REVISION OF THE AUSTRALIAN CURCULIONIDjE, 



Posterior femora slightly passing apex of elytra. Length 8, 

 rostrum 2|; width 3f mm. 



ZTaft.— KS.W. : Tweed River. 



A very distinct species, rendered so by the length and alirupt- 

 ness of the posterior declivity, the elytra when seen from the 

 sides (in conjunction with the sides of mesosternum) appearing 

 almost quadrate. It is perhaps more densely clothed with scales 

 than any other species allied to I'orofterus; several species of 

 the subfamily are squamosa at apex or sides of pectoral canal, but 

 in this species the canal is densely clothed with distinct scales 

 for its entire length; the scales almost entirely conceal the sutures 

 of the under surface. Seen from above the prothorax appears to 

 be nearly the length of elytra. 



Genus D e c i L a u s, Pascoe.

Head rather large, not concealed by prothorax. Eyes rather

 of abdomen large, intercoxal process very wide, truncate; inter- 

 mediates very short. Legs short ; femora moderately thick, 

 edentate, veiy distinctly grooved, posterior terminating either at
