Eyes as in preceding species. Rostrum with sides almost con- 

 tinuous witli those of head; median channel fairly deep and but 

 slightly dilated in front; sublateral sulci feebly curved, shallow and 

 open in front, deep and open behind. Prothorax moderately trans- 

 verse, sides strongly rounded; with very large depressed granules 

 or small tubercles. Elytra with outlines as in preceding species; 

 with rows of large, transverse, and rather deep punctures; with 

 small granules distinct from the sides, but scarcely visible from 

 above. Apical segment oi' abdomen with a deep excavation, occupying 

 mostofits surface, and at apex traversed by a still deeper impression; 

 a small tubercle near apex on each side of excavation. Length IS- 

 IS mill. 



Hab. : S. Australia : Adelaide, Port Augusta (Belgian Museum) (1). 



In general appearance close to preceding species, but tibiae not 

 notched, and abdominal excavation of male very different. This 

 excavation will readily distinguish it from the males of Howitti, 

 Riverince, and morbillosa. 



The inner ridges of the rostrum are almost parallel, so that the 

 elevated parts between the scrobes have very little resemblance 

 to an M. 



Some specimens which appear to be females of the species have 

 the outer ridges of the rostrum not quite parallely, the scape some- 

 what thinner, the elytra wider and more ovate, and the apical 

 segment of abdomen largei', not largely excavated, and with a 

 shining, depressed, impunctate median space. 



568. TALAURINUS CAVIROSTRIS n. sp. 



Black. Densely clothed with short muddy grey or brownish 

 pubescence (scarcely scales'). In addition with more or less dark 

 setge. Under surface rather sparsely clothed. 



Head with a feeble median ridge in front, towards each side with 

 an obtuse oblique ridge. Rostrum not much wider than long, with 

 a strongly elevated ridge above each scrobe, each ridge bifurcated 

 at base and abruptly terminated; the median space widely and 

 deeply excavated, and without sublateral ridges, shallowly depressed 

 along its middle, and with an oblique impression on each side near 

 apex. Antennae, for the genus, rather thin. Prothorax feebly trans- 

 verse, base slightly narrower than apex and both truncate, ocular 

 lobes very feeble, sidesfeeblyincreasingin width fromapex to beyond 

 the middle and then coarctate to base ; with large but very obtuse 



(1) D' Ferguson informs me that he has a specimen from Glenample (Victoria).
