Belus rubicundus, n sp. 



Red; extreme apex of rostrum, 3rd tarsal joint and apex of 4th 

 piceous; antennae infuscate towards apex; head sometimes piceous. 

 Sides of eyes and scutellum with white hairs, prothorax without 

 white median line, elytra with a few scarcely visible hairs about 

 suture and with three or four small and rather distant spots 

 towards the apex, of which the apical one is rather elongate. 

 Under surface regularly but not densely clothed with pale yellow 

 hair, each of the four basal segments of abdomen with a rounded 

 nude space on each side. 



Head densely granulate, longer behind eyes than usual. 

 Rostrum long, feebly curved, highly polished; moderately densely 

 punctate at base, scarcely visibly so elsewhere. Antennte elongate, 

 1st and 3rd joints subequal, 2nd short, 7th-llth considerably 

 wider in ^ than in 9, 11th in ^ about once and one-fourth 

 longer than 10th, in $ about twice. Prothorax slightly longer 

 than wide, apex subtubular, sides behind apex strongly rounded; 

 median line rather strongly impressed at base. Elytra parallel- 

 sided to near apex, very narrow; densely and strongly punctate, 

 from some directions appearing granulate; slightly longitudinally 

 depressed on each side of suture, suture itself feebly I'aised and 

 densely and minutely punctate; each elytron feebly separately 

 rounded, not produced. Femora edentate, posterior scarcely 

 extending to apex of 1st abdominal segment. Length 8^, beyond 

 abdomen \, rostrum 1^; width 1| mm. 



Hah. — Swan River, W.A. 



Allied to acicularis, Pascoe, but the clothing of the elytra and 

 under surface will serve to distinguish it. My specimens range 

 in size from 8 to 10 mm. 



Belus longicornis, n.sp. 



(J. Piceous-brown, legs paler except the apical tarsal joints, 

 rostrum dark brownish-red. Eyes distinctly margined with pale 

 hair, prothorax with a rather feeble median line, scutellum 

 clothed, elytra nude except for a small longitudinal spot on suture
