206 REVISION OF THE AUSTRALIAN CURCULIONID^, 



Very distinct from the preceding species on account of its 

 stronger and less numerous elytral tubercles and very different 

 prothoracic carina 



Hexymus subplanatus, n.sp. 



Q. Black, opaque ; antennae pale red, club slightly darker ; 

 rostrum, except basal fourth, highly polished. Upper surface 

 densely clothed with minute muddy-brown scales and with 

 elongate darker scales scattered about, especially on prothorax. 

 Under surface and legs more densely clothed than upper and 

 with numerous elongate scales; head and basal fourth of rostrum 

 densely squamose. Ciliation minute, silvery. 



Head slightly convex, ocular fovea invisible. Pvostrum some- 

 what stouter than in either of the preceding, basal third rather 

 strongly carinate and punctate, elsewhere minutely and sparsely 

 punctate. Antennte moderately long; scape inserted slightly in 

 advance of middle of rostrum and just passing apex; 2nd joint of 

 funicle scarcely twice the length of 1st, slightly longer than three 

 following combined and slightly shorter than club, 7th distinctly 

 transverse. I'rothorax as in monachits except that the sides are 

 less rounded in the middle and the disc less convex. Elytra at 

 base wider than prothorax and widening to beyond the middle, 

 basal half somewhat flattened, sides precipitous; each with four 

 moderately large flattened tubercles, two on the 3rd and two on 

 the 5th interstices, suture with about six small granules; seriate- 

 punctate, punctures near suture large, subquadrate, subapproxi- 

 mate ; posterior declivity at an angle of about 60°, somewhat 

 rounded, distinctly but not strongly punctate, without callosities. 

 Claw-joint glabrous. Length 6|, rostrum 21; width 3^ mm. 



^^/^(.—IS'.S.W. : Burrawang (Mr. T. G. Sloane). 



In appearance closer to monachus than the preceding; differs 

 in its much stronger sutural punctures, each elytron with but 

 four tubercles, much paler antennae the funicular joints of which 

 are shorter, slightly shorter and wider rostrum, itc. ; from the 

 preceding the shape of the elytral tubercles and prothoracic carina 

 at once distinguish it.
