Eev. T. A. Marshall's monograph of 



In Sect. III. the impressed lines upon the 2d segment 

 are not marginal or lateral, but discal. When the seg- 

 ment is only margined by impressed lines afterwards 

 converging to the base, as in glomeratus, the species is 

 referred to Sect. I. 



In Sect. IV., when the 1st segment happens to be 

 somewhat more broadly rounded than usual, care must 

 be taken not to regard it as truncated. 



With these unavoidable exceptions, the sections are 

 sharply defined, and almost any species may be referred 

 to its place with certainty.
