Talauhinus plagiatus, 11. sp. 



<S . Size, shape, and general appearance of T . septen- 

 trionalis, intermediate tibiae without subapical notch. Black, 

 rather densely clothed with dingy-grey subpubescence, an 

 obscure dark patch at each humeral angle, a few small indis- 

 tinct dark maculae on disc; beneath with fairly close silvery 

 subsetose clothing; setae dark-brown. 



Head strongly convex, separately so from rostrum. 

 Rostrum short, strongly excavate in front; external ridges sub- 

 parallel; internal prominent, little convergent; median area 

 depressed, sublateral sulci long, subparallel. Scrobes feebly 

 curved, well denned, not reaching eye. Eyes rather large, 

 ovate. Scape rather short, stout, strongly curved, incrassate, 

 but not ampliate or explanate at apex. Prothorax (3x4 

 mm.) rather strongly widened, subangulate at sides, anterior 

 to middle; apex with moderately distinct median lobe, but 

 feeble ocular lobes ; postapical constriction ill-defined but 

 moderately strongly impressed, median line indefinite; with 

 small obscure granules fairly closely set, rounded, somewhat 

 irregular towards middle with tendency to coalesce longi- 

 tudinally; sides granulate. Elytra (7x5 mm.) ovate in out- 

 line, base subtruncate, humeri marked but not produced, apex 

 strongly rounded, posterior declivity steep ; with rows of open 

 shallow foveae in striae, the granules between small and little 

 evident; interstices little raised, alternate ones rather thicker, 

 setigerous but hardly evidently granulate, the whole sculpture 

 somewhat obscure. Beneath with intermediate ventral seg- 

 ments moderately long, flat ; fifth segment feebly and indefin- 

 ably concave in middle near apex. Forceps hardly visible in 

 position, short, with moderately broad laminae set obliquely 

 across inner face. Anterior tibiae strongly angulate at apex, 

 intermediate without subapical notch. 



9 . Similar, more ovate ; under-surf ace convex without 

 impressions, anterior tibiae not so strongly angulate at apex; 

 'disc with granules feeble but slightly more evident. 



Dim. — $ , 11x5; Q, llx5'5 mm. 



Hab. — North Queensland (Blackburn). 



Type in South Australian Museum. 



A small obscure species in appearance strongly resembling 

 T. septentrionalis , but with simple tibiae. It is perhaps closest 

 to T. panduriformis, but, besides being smaller, it has more 

 evident prothoracic granules, and rather more regular elytral 

 sculpture, the punctures being more definite and the inter- 

 mediate interstices (i.e., the second and fourth) with more 

 evident setae set close together; the difference in the humeral 

 .angles is also very marked.
