Rah. — Queensland: Tambourine Mountain (the author). 



A single specimen, taken in January, 1912, can easily be 

 distinguished from S. catenulata, Bois., and S. proximo,, Pasc, 

 by (1) the undentate hind angles of prothorax, (2) colour 

 intermediate between the dull-black of catenulata and the 

 clear-bronze of proximo, m (3) the catenulate costae longer and 

 less tuberculose than in proximo, wider and less elongate than 

 in catenulata, and (4) the seriate punctures larger than in 

 either of the above species with the basal half showing trans- 

 verse reticulation. Type in author's collection.
