598 REVISION OF THE AUSTRALIAN CURCULIONIDiE, X., 



wliich the 1st is near base and 2nd slightly before middle; 4th 

 interstice with three small tubercles before middle and a some- 

 what prominent one on posterior declivity; suture feebly raised 

 throughout, basal two-thirds margined with small shining granules; 

 striate-punctate, punctures more or less obscured by scales, very- 

 small on posterior declivity; interstices wider than punctures; 

 apex feebly emarginate, in some specimens (owing to clothing) 

 appearing entire. Meiasternal episterna densel}'' punctate, punc- 

 tures squamose. Legs densely punctate, anterior femoral teeth 

 somewhat acute, posterior somewhat obtuse; posterior femora 

 extending to apex of 3rd segment. Length lOJ; rostrum 3; 

 width 5(vix)mm.

A specimen from Mt. Kosciusko differs in being somewhat 

 smaller, in having the rostrum not perfectly straight, and in 

 having the punctures much more distinct. Length 9, rostrum 2|; 

 width 4i mm. 



This species may be readily distinguished from the following 

 by its fasciculate and non-carinate prothorax, convex form, and 

 puncturation of metasternal episterna. In the Kosciusko speci- 

 men the rostrum appears to be perfectly straight, but, on looking 

 at it from the side, a very slight curvature is noticeable.
