Upper-surface sparsely, the under-surface moderately densely 

 clothed with whitish pubescence. 



Head densely granulate-punctate. Rostrum long, thin, 

 lightly curved, shining, and with minute punctures, but 

 becoming more distinct near base. Antennae thin and rather 

 long, first joint about as long as second and third combined, 

 second shorter but somewhat stouter than third, third and 

 fourth equal, eleventh about once and one-half the length of 

 tenth. Prothorax slightly longer than wide, median line 

 narrow; densely granulate-punctate. Elytra very narrow, 

 slightly wider than prothorax, slightly narrowed towards but 

 scarcely produced at apex, suture not distinctly elevated at 

 base; with closely-set punctures, somewhat larger towards 

 base than elsewhere. Front femora rather long and lightly 

 dentate, the others shorter and edentate, hind ones just 

 passing tip of first abdominal segment, basal joint of tarsi 

 almost as long as the two following combined. Length, 7 mm. 



Rah. — New South Wales: Mittagong (A. M. Lea). Type 

 (unique), I. 7884. 



The abdomen is more sparsely clothed than on acaciae, 

 and the sublateral spots are narrower and much less defined ; 

 the species also differs from acaciae (with which it might be 

 associated in my table) in being narrower, pale clothing of 

 elytra much sparser and confined to suture, rostrum distinctly 

 longer, etc. The clothing of the under-surface, although not 

 very dense, is almost uniform except for a narrow glabrous 

 (but not very sharply defined) spot on each side of each of the 

 four basal segments of abdomen, the metasternal episterna 

 are very narrowly glabrous where they touch the elytra, but 

 are without distinct nude spots; the head (except for a feeble 

 ring around each eye) and pronotum (except for a feeble and 

 partial median line) are almost glabrous, on the elytra the 

 clothing consists of small and feeble spots, somewhat distantly 

 placed along the suture. The elytral punctures are placed in 

 almost regular rows, but the punctures in the rows, and the 

 rows themselves, are so close together as to be practically 

 touching. 



Belus acutipennis, n. sp. 



Piceous-brown ; rostrum and legs somewhat paler. 

 Sparsely clothed with whitish pubescence. 



Head convex and densely granulate-punctate between 

 eyes; finely punctate at base. Rostrum slightly longer than 

 prothorax, thin, lightly curved, shining : at extreme base with 

 fairly strong punctures, elsewhere with very small ones. 

 Antennae rather long and thin, but five apical joints somewhat 

 thickened, third slightly longer than first, distinctly longer
