490 REVISION OF THE AUSTRALIAN CURCULIONID.E, 



feeble: constriction absent; sides tinangiilaily widening, rounded 

 in the middle, very feebly decreasing to base; disc feebly convex, 

 the position of transverse tubercles (which are entirely absent) 

 feebly marked by scales, median line not at all or very feebly 

 marked at base and apex. Elytra about twice the length of 

 prothorax, wider at the base, and widest a short distance behind 

 it, base appearing trisinuate from a somewhat triangular project- 

 ing tubercle on each shoulder, and a thickening on each side of 

 suture, between wdiich rests a feeble scutellar lobe ; tubercles 

 smaller and in position somewhat different from those of the 

 preceding, two onl}' on disc of second interstice, one at summit 

 of declivity, the other a little before it, largest tubercle a 

 little before middle of declivity, distinctly on 2nd interstice but 

 partly on 3rd, 3rd near base with a tubercle taking the place of 

 basal on "ind of the preceding species, 4th with two feebler ones 

 similar in position to the preceding, and just behind largest 

 tubercle a distinct one, seen from behind the four form a trans- 

 verse row^j sides with feeble tubercles, an obtuse tubercle on each 

 side at apex; punctures a little larger and more irregular than in 

 the preceding. Basal segment of ahdumeu vevy flat, almost as 

 long as three following combined, transversely impressed near 

 apex, 2nd shorter than intermediates, these a little longer than 

 apical, apical in ^ feebly transversely impressed. Z,-^(/« mode- 

 rately long; femora in (J reaching apex of abdomen, in ^ middle 

 of apical segment; tibiiij compressed, feebly curved; tarsi a httle 

 wider and the 3rd joint a little more distinctly bilobed than in 

 the preceding species. Length 11, rostrum 3; width 4| mm.

In all my specimens the curvature of the mesosternal receptacle 

 differs; in one very much abraded specimen it is almost straight; 

 the anterior portions perhaps have been worn down by friction 

 with the coxae and in crawling about. They are all undoubtedly 

 conspecific but each is slightly different i7de7- se ; one has the 

 humeral tubercles more distinct and with a granule at its base; 

 in another the base is flatter; the tubercles are larger in some 

 than in others; the size of the 2nd abdominal segment appears
