870 AUSTRALIAN COLEOPTERA, WITH DESCRIPTIONS OF NEW SPECIES, 



disc (in some specimens the tuberculation is very obsolete) ; the 

 disc is furnished tolerably evenly with rather close-set granules or 

 small tubercles ; the suture is scarcely elevated in any part ; the 

 three ridges usual in this section of Saragus are represented, the 

 1st by a strong straight (not undulating as it is in S. IcevicolHs) 

 costa not reaching the apex, and having its apical half (or more) 

 broken into tubercles, — the 2nd by a similar costa, which, how- 

 ever, is in most examples broken into tubercules from just behind its 

 base, — the 3rd by a row of tubercles ; each of the intervals 

 between the suture and the 1st costa, between the 1st and 2nd 

 and between the 2nd and 3rd costae is occupied by a row of 

 tubercles somewhat larger than those that form the general 

 granulation of the surface, but there is no serial tuberculation 

 whatever outside the 3rd costa. Tlie spur of the anterior tibiae is 

 very much more slender and pointed than that of S. IcevicoUis. 

 This species is not very close to any other Saragus known to me. 

 Its subhemisphseric form and shining surface will distinguish it from 

 most of the species with the anterior tibine strongly spurred.

S. MEDiocRis, sp.nov. 



Subopacus ; late ovatus ; brunneo-niger ; capite protlioraceque 

 confertim subtiliter granulatis ; hoc quam longiori plus duplo 

 latiori, minus late marginato, margine antico vix concavo ; elytris 

 minute granulatis, tricostatis (costis undulatis plus minus inter- 

 ruptis), interstitiis seriatim tuberculatis ; tibiis auticis calcare 

 breviori obtuso minus gracili instructis.

The head and prothorax scarcely differ from the same parts in 

 tS. Lindi, except in the intermediate expansion of the latter being 

 a little narrower. The elytra also resemble those of the same 

 species almost exactly in respect of their cost* and rows of 

 tul)ercles ; there is, however, no well-defined row of tubercles 

 running down the sides of the suture ; the sui'face of the disc is 

 very much rougher (making the small granules umch less con- 

 spicuous) than in S. Lindi : the elytra are very little narrowed at
