tubercles depressed, granuliform. Undersurface with a some- 

 what ill-defined but deep furrow on either side of median vitta 

 at base; fifth segment with an oblique, longitudinal depression 

 on either side, extending on to fourth segment. Anterior femora 

 not ridged beneath; tibiae simple; anterior tarsi with third joint, 

 and, to a less extent, the second, asymmetrical, the inner portion 

 broader and more expanded than the outer. 



9. Differs in its more robust form, convex undersurface, the 

 fifth segment with a shallow, transverse, apical impression, less 

 hirsute vitta, and in the simple tarsi.

Described from specimens in my own collection. I have in- 

 cluded this species in Group v., although the tubercles are present 

 at intervals alonsf the whole lenerth of the fifth interstice. In 

 general appearance, however, it is more closely related to the 

 species of this Group than to any other. It will be noted that, 

 in almost all the Groups, there are species presenting this pecu- 

 liarity; and Macleay placed them together in his third aggregate. 

 In all cases, however, the general appearance and other details of 

 sculpture show the true affinities. I refer specimens from Con- 

 dobolin, with some doubt, to this species; they differ somewhat 

 in the colour of the clothing, in the more sparsely granulate pro- 

 thorax, and, to a slight extent, in the elytral sculpture. The 

 species is variable in size, and S. aiigusfatfis seems to me only a 

 small male, although the setae on the pi'othorax are of a paler 

 colour.
