elytra with sides rounded from near base, a slight emargina- 

 tion beyond middle, apex not trilobed, and third interstice 

 not conspicuously elevated at base ; legs somewhat shorter and 

 denticulation of tibiae very feeble. 



Hob. — North-western Australia: Parry Island and 

 "Queen Islet. Type in British Museum. 



A remarkably distinct species in a genus of gloomy and 

 usually closely-allied weevils. On the male the sides of the 

 elytra about the middle are subangularly dilated, and near 

 the apex they appear tubsrculate, owing to the space between 

 the second and fifth interstices being somewhat prolonged, in 

 consequence the apex appears to be trilobed, with the median 

 lobe somewhat in advance of the others. The incurvature of 

 the sides that starts about the middle allows free movements 

 to the hind femora. On the female there is a feeble notch on 

 each side just where it is touched by the femur. 



POLYPHRADES CRASSICORNIS, n. Sp. 



<3 . Black. Densely clothed wih muddy-grey scales,, 

 becoming paler, and sometimes with a bluish gloss, on muzzle, 

 under-surface, and legs. In addition with dense, short, sub- 

 erect setae. 



Head wide and rather convex ; punctures concealed ; with 

 a narrow median line, continued to apical triangle of rostrum. 

 Rostrum short, narrowed from base to apex, without a trans- 

 verse basal impression. Antennae stout; scape scarcely more 

 than half the length of funicle and club combined; basal-joint 

 of funicle as Ions: as three following 1 combined. Prothorax 

 rather strongly transverse, sides strongly rounded ; with dense 

 flattened granules. Elytra at base slightly wider than base 

 of prothorax, sides parallel for a very short distance, then 

 strongly rounded, and widest just before middle (where the 

 width is slightly more than the middle of prothorax) ; with 

 rows of large, partially concealed punctures, becoming smaller 

 posteriorly; third interstice decidedly elevated and thickened 

 at base, but becoming level with the others before the basal 

 fourth. Legs rather stout; four front tibiae feebly denticu- 

 late. Length, 5-6 mm. 



9 • Differs in having the sides of prothorax slightly less 

 dilated and the elytra with the third interstice very feebly 

 elevated at the base. 



Hah. — Northern Territory: Batchelor and Darwin (G. F. 

 Hill's No. 308). Type, I. 3331. 



The unusually short rostrum, stout antennae and legs, and 

 conspicuously elevated base of third interstice of male, should 

 render this a fairly distinct species.
