'2d'2 revision of the Australian curculion'id.e, vii., 



The only genus in the subfamily (at least in Australia) in 

 which the claw-joint is entirely absent. The species are all 

 denselv clothed with a ground layer of white closely adpressed 

 scales, and with black or brown scales forming various and often 

 extremely variable patterns. 



Ehtra striped lineatus, Pasc. 



Elvtra maculate. 



Apex of elytra entire $triatu.<i, n.sp. 



Apex of elytra feebly emarginate. 



Rostrom with a few scales at base, form narrow. 



Antennae black pa chy pus, n.si^. 



Antennae tinged with red argu.?, n.sp. 



Bostram entirely nude, form broader. 



Scales of upper surface white and black luctuogus, Pasc.

Black, rostrum highly polished, eyes dark brown. Densely 

 clothed all over with white scales mixed on the upper surface with 

 sooty-brown scales, forming on prothorax a broad median stripe: 

 on elytra there is usually a broad sutural stripe to about the 

 middle, when it is suddenly directed outwards to the margins and 

 then becomes marginal to apex, but very irregidar; there are 

 usually three large irregular patches of white scales, one on each 

 side at and behind shoulders, and one behind the middle about 

 suture; head with a patch of sooty-brown scales behind eyes; 

 rostrum entirely nude. Ciliation short, sparse, white, moderately 

 distinct when head is removed. 



Head denselv punctate ; ocular fovea shallow, indistinct. 

 Rostrum the length of prothorax, distinctly curved, in g slightly 

 enlarged at insertion of antennae ; densely punctate at base, 

 margins and extreme apex less noticeably punctate, smooth else- 

 where. Scape not as long as two basal joints of funicle, these 

 subequal, 2nd as long as twofollo%ving combined, 5th-6th globular, 

 7th transverse. Prothora:>: in ^ slightly longer than wide, in 9 

 about equal in length and width, apex about half the width of 

 base, base strongly bisinuate, sides straight, posterior angles
