In this subgenus the head is small ; the scutellum broadly quadrate, shield-like, and 

 perfectly flat ; the metathorax broad and without spines or tubercles ; the legs short 

 and stout; the abdomen short, broad, ovate, depressed, longitudinally rugose or 

 aciculated, with the segments more or less constricted at the base. (Cresson.)

TROGUS. 



Trogus, Panzer, Krit. Revis. ii. 1806, p. 80. 



The species here included in this genus are typical forms, excepting perhaps 

 T. excellens, which has not the scutellum quite so sharply peaked as the others ; but it 

 agrees so closely otherwise with T. ornaticomis that I do not see how the two can be 

 separated generically. But see my remarks on pp. 136, 137.
