As I have recently fully described the type of A. morosus Boisd., 

 a further description is unnecessary here. 



Specimens in my collection from Victoria(?), differ somewhat 

 from Tasmanian specimens; and may, perhaps, belong- to a dis- 

 tinct species. I liesitate to describe them as distinct, as Tasmanian 

 species appear to vary somewhat. They differ principally in the 

 almost obliterate sculpture; in one male, the prothoracic granules 

 are ahnost obsolete ; in another, they are more distinct ; in both, the 

 elytral tubercles are small and almost obsolete, and the punctures 

 are hardly traceable. The specimens of a Tasmanian series before 

 me (5) show some variation in the size of the tubercles , and one male 

 lias them almost as small as in the supposed Victorian specimens; 

 a female is also hardly separable from a Victorian ( ?) female. 

 These specimens, I attribute to Victoria principally because they 

 were received from Mr. C. French, of Melbourne. I have, how- 

 ever, seen undoubted Victorian and South Australia specimens 

 which I attributed to S, huhalus.
