near middle, five with about eight, sixth with six forming 

 lateral border; sides with tubercles subobsolete and closer. 

 Beneath with small scattered setae, intermediate segments long ; 

 fifth with shallow impression occupying a little more than 

 middle two-fourths, deeper posteriorly and with a deep narrow 

 somewhat boat-shaped fossa at extreme apex. Anterior 

 femora not ridged. 



9 . Similar to d" but more robust, with elytral tubercles 

 somewhat more numerous; beneath strongly convex, fifth 

 segment with only a shallow transverse apical impression. 



Dim. — J , 20 x 8 mm. ; 9 , 22 x 9 mm. 



Hab. — Kangaroo Island. 



Type in South Australian Museum. 



Very close in general appearance and elytral sculpture 

 to T. verrucosus, Guer., but, inter alia, with somewhat 

 different excavation of fifth ventral segment. The excavation 

 in both species is on the same general plan, but is much deeper 

 in T. verrucosus, while the tubercles at the sides are not 

 developed in T . halmaturinus ; the internal rostral ridges are 

 also more evident in the Kangaroo Island species. T . tuber- 

 culatum differs again in these respects. 



Talaurinus bubaroides, n. sp. 



9 . Small, ovate. Black, densely clothed with yellowish 

 -or grey subpubescence, completely covering the granules; setae 

 small, light coloured. . 



Head as viewed from above about twice as wide across 

 eyes as width across external rostral ridges at apex, sides nar- 

 rowed with slight curve outwards from behind eyes to base 

 of rostrum. Rostrum little excavate, median area wide, 

 shallow, and open; width across external ridges much less 

 than width of rostrum, ridges not prominent, slightly diver- 

 gent backwards ; internal ridges little prominent, sublateral 

 sulci small, foveiform at base, becoming rapidly shallower 

 anteriorly; sides of rostrum greatly bulged out below scrobes. 

 Scrobes somewhat curved with shallower extension continuing 

 curve back and downwards to orbit. Scape moderately long, 

 normal. Eyes rotundate. Prothorax (3 x 4'5 mm.) strongly 

 transverse, sides strongly angulate in middle, narrowed to 

 base and apex; ocular lobes rather well marked. Disc strongly 

 convex from side to side, with median impressed line and 

 strongly marked, somewhat flattened, impression on each side, 

 making the lateral margins appear almost explanate. 

 Granules small, discrete, densely clothed but readily traceable, 

 absent along longitudinal impressions, clustered more thickly 

 around lateral angle. Elytra (7x5*5 mm.) rather strongly
