124 REA-ISION OF SYMPETES AND HELiEUS, ETC., 



differently sculptured elytra with its "rows of deep square closely 

 placed punctures " The specimen has evidently lost much of the 

 squaraose clothing with which it appears to have been clad. It 

 forms a connecting link between Macleay's Section ii., Subsection 

 1, and Subsection 2, since the smaller rows of nodules may be 

 described as granular, while the larger form distinct costse 

 irregularly interrupted. There are three kinds of such rows, 

 {i.) three equidistant interrupted costse; (ii.) less raised lines of 

 nodules intermediate and exterior toi.; and (iii.) still smaller lines 

 of granules irregularly spaced but generally evident between and 

 exterior to ii. Type in Macleay Museum.
