Hah. — New South Wales: Mudgee. Type in Australian 

 Museum. 



The above description was drawn up from the type in the 

 Australian Museum. The type of S. interriiptus Macl., also a 

 female, in the same collection, was examined on the same occa- 

 sion, and the following notes made: 



$. Smaller than *S'. subsequens; head and rostrum similar; pro- 

 thorax (3-5 X 4*5 mm.) with granules slightly less prominent, 

 rounded. Elytra (9x6 mm.) with punctures shallower; second 

 interstice with four or five, isolated tubercles, shorter and more 

 raised, not at all costiform; third with about nine tubercles, the 

 basal five connected, forming an irregular costa; fourth without 

 tubercles; fifth with twelve tubercles, more elongate than in >S'.
