wliich certainly would not apply to any specimen I have seen of 

 the above. <S^. arviaticeps, Mad., and chlorotica, GylL, have a 

 strong transverse ridge on the clypeus ; nigrolineata, Boisd., is not 

 intelligibly described but seems to have a pattern-like marking on 

 the elytra ; sericans, Er., has the hinder part of the head blackish 

 and the punctiiration "obsolete"; langmda, Er., is a coarsely 

 rugulose species. 



S. Australia ; widely distributed.

I believe the two examples (in my collection) of this species to 

 be male and female although I can discover no difference between 

 thera except in the pygidium of one (probably the male) being 

 strongly tumid and the apical ventral segment being feebly 

 wrinkled transversely, with puncturation obsolete (this segment is 

 almost sti'aight behind in both examples), while in the other the 

 pygidium is scarcely tumid and the apical ventral segment is not 

 wrinkled and is much more distinctly punctured. The colour 

 of both examples is brownish-ferruginous and the shape is 

 much like that of -S'. jilanics'ps (female). The clypeus in both 

 examples is even more strongly reflexed in front than in S. 

 planiceps (female) and in the male is emarginate in the middle of 

 the front. Otherwise it does not differ much from *S^. planiceps 

 except in the tarsi being much shorter and more slender (con- 

 siderably more so than in S. p>ruinosa, Dalm.) with their underside 

 more setose.
