 marked angle on each side at widest part; base truncate. Elj^tra 

 oval (3-1 X 2'25 mm..), convex, sunbitid, shagreened, not sericeous,

Hah. — Tas. : Mt. Wellington (given to me by Mr. A. M. Lea, 

 Government Entomologist for Tasmania, as having been taken by 

 Mr. H. H. D. Griftith, " half-way to summit on marshy ground"). 



Can only be compared with S. cBJieus, Macl., amongst Austra-

 Tachys nervosus, n.sp. 



Oval, robust. Testaceous. Each elytron 17-striate and without 

 apical striole. 



Head shagreened; a short slightly raised intramarginal frontal 

 ridge extending backwards from base of clypeus on each side 

 between anterior part of eyes; frontal longitudinal impressions 

 feeble. Prothorax transA^erse, subdepressed, wider at base than 

 at apex, rugulose — the rug?e transverse in middle of disc, longi- 

 tudinal near apical and basal margins — sides lightly rounded on 

 anterior three-fourths, sinuate posteriorly and meeting base at 

 right angles; apex widely emarginate; anterior angles subpromi- 

 nent, obtuse (not advanced), base truncate on each side, widely 

 but lightly produced backwards in middle; basal angles rectangular; 

 marginal channel wide before posterior lateral sinuosity, narrow 

 near basal angle, its inner margin subcarinate, more stronglj^so near 

 base; lateral basal impressions wide, flat (not concave); a lightl}^ 

 impressed arcuate transverse impression defining the sublobate 

 median part of base. Elytra convex, oval, wider than prothorax; 

 17 striae on each elytron; lateral channel incurved at humeral 

 angle to meet lOtli stria; interstices forming narrow subequal 

 ridges, 17th intprstice C-^ lateral interstice") of normal width,
