Five specimens (all males) of this insect occurred to me on 

 the Buffalo and other mountains of the Victorian Alps, at a 

 high elevation. The species resembles S. eucalypti, Boisd., 

 of same sex, in its 6-laminate antennal flabellum (the 

 laminae, however, are distinctly longer, especially the basal 

 one in proportion to the others), but differs strongly in the 

 absence of a sternal process ; the sternum ending at the level 

 of the intermediate coxae as an obtuse carina vertically trun- 

 cate. Other notable distinctions consist in the clypeus not 

 reflexed in front, the much less fine asperity of the pygidium, 

 the much less fine and less close puncturation of the ventral 

 segments, the greater length and less robustness of the tarsi, 

 the evidently more strongly developed external teeth of the 

 front tibiae. From the insect mentioned above as Icetus, 

 Blanch., this species differs by, inter alia multa, the 6- 

 laminate antennal male flabellum and the absence of a 

 sternal process; from S. monticola, Blackb., by the male 

 antennal flabellum with 6 long laminae, the pronotum non- 

 pilose and thinly punctulate, etc. ; from piliger, Blanch., and 

 nigrescens, Blanch., by, inter alia multa, its very much 

 greater size. It should, perhaps, be added that I have taken 

 a Sfethaspis (female only) in the Dividing Range of Victoria 

 which may possibly be the female of this species, but since 

 its sternal process is distinctly less obsolete than in the males 

 from the Alps (not, apparently, a sexual character in other
