The author remarks: "Thepuucta are almost alwaj-s arranged in radiat- 

 ing rows; three, four, or more holes in each row, and these being at equal 

 distances they form concentric lines. In T. granulatus, two of the rows 

 are separated by a fiirrow from the rest; in T. seticornis, three are distinct 

 from the remaining two or three, by the front rows being sunk in a deep 

 concentric furrow. Other modifications take place. In T. fimbriatus, the 

 two front rows are turned downwards; lastly in T. ornatus, the dots occur 

 most frequently in quincunx order."
