448 REVISION OF THE AHYCTERIDES, V., 



Head convex, slightly concave between the crests, with two, 

 small granules on forehead; supraorbital crests comparatively 

 large, upstanding. Rostrum shoi-t, wide: upper surface gently 

 concave. Scape rather robust. Prothorax ("2 x 3 mm.) dentate 

 at sides, with two, moderately large, conical projections anterior 

 to middle, and a row of smaller, conical granules, about four in 

 number, posterior to middle; a small, conical granule also pre- 

 sent in front of subapicai constriction; disc with median line 

 shallowly, but distinctly, impressed, elsewhere closely set with 

 rather large, upright granules, each bearing a long seta; sides 

 granulate above. Elytra (7x4 mm.) subparallel on the sides; 

 base not emarginate, humeral angles rounded; stria- modeiately 

 deeply impressed, punctures small, indistinct; interstices each 

 with a single row of small granules, more distinct posteriorly 

 and laterally; sides with interstices non-granulate. Under- 

 surface gently concave at base; with scattered, setigerous punc- 

 tures, rather coarser on the apical segment. Anterior coxae 

 contiguous, anterior tibise feebly curved, posterior feebly curved, 

 also veiy feebly curved inwards; all the tibiie clothed with long, 

 setose hair, most noticeable on the undersurface, the posterior 

 with a few, fine granules traceable among the set*. 



^. More ovate ; undersurface more convex, posterior tibise 

 practically straight. Dimensions : (J, lOx 4 mm.; 5, 11 x 5 mm. 



Hab. — North-west Australia, Onslow. 



Type in Coll. Ferguson. 



Closely allied to C. spintcoUis, but a larger species, with larger, 

 almost conical granules on the prothorax, and longer sette, par- 

 ticularly on the prothorax. 



The type is possibly immature, as it is of a decidedly reddish 

 colour, other specimens being black. The Onslow specimens 

 differ slightly in the prothorax, and the elytral granules are 

 slightly more evident; I do not think, however, that they are 

 distinct. 



CuBicoRRHYNCHUS MussoNi Blackb. 



Blackburn, Proc. Linn. Soc. N. S. Wales, 1892, p.l24. 



This species is very distinct from all other described Cubi- 

 corrhynchi with the exception of the following, C uuriculatus.
