Upon liead, nietliaii carina strong, about as broad as external 

 ridges; sublateral sulci rather shallow, deeper at base. Prothorax 

 (-l:X5mm.) subangulate on sides, widest in front of middle; 

 subapical impression rather indefinite; moderately closely set with 

 large, rounded, slightly depressed tubercles, varying slightly in 

 size, and irregularly placed; sides not granulate. Elytra (10x6 

 mm.) not greatly widened posteriorly; base rather strongly emar- 

 ginate; humeri with a rather large, projecting tubercle; punctures 

 not traceable; interstices with strong, conical or subconical 

 tubercles; sutural with a row of fine, distant granules; second 

 with a row of eight tubercles, set at even distances, less than the 

 length of a tubercle, extending from near base down on to de- 

 clivity; third with a similar row of ten from base down on to de- 

 clivity; fourth with six, not reaching base, nor extending down 

 declivity ; fifth with twelve, slightly smaller, subconical, out-turned ; 

 sixth with thirteen, slightly smaller and less conical. Sides with 

 strong, vertical ridges, separated by deep furrows, the ridges run- 

 ning up on to, and including the tubercles of the sixth interstice. 

 Beneath, convex; ventral segments with irregular imi)ressions on 

 each side; fifth with a shallow, transverse impression near a;pex. 

 Dimensions : ^, 16 X 6 mm. 



Hah. — New South Wales. Type in Macleay Museum. 



Though closely allied to iS. elongatus Bohem. (?), this species 

 may be readily identified by the tubercles on each interstice being 

 well separated from one another. I have a male, which was taken, 

 I believe, at Blackheath, on the Blue Mountains, and which I refer, 

 with slight doubt, to this species. It has the ventral vitta black. 

 Probably this species has a wider range inland, as I once took, at 

 Wellington, the remains of a Sclerorinus, which appeared to be S. 

 verrucosus. 



Group iv. 



Fifth elytral interstice tuberculate throughout; intermediate 

 tibiae with a strong, subapical emargination. 



Though but few in number, the species of this Group are very 

 homogeneous in their general type of structure The Group is, 1
