stria antice interrupta; elytris punctulatis, macula pallida transversim notatis; pygidio conico, elongato, 
apice obtuso; propygidio magis grosse punctato; prosterno mesosternoque validis marginatis ; metasterno

Three examples. Only the female of this species has yet been discovered ; it may 
be placed in the list between 7. pictus and T. bisulcifrons, Mars. In outline it repre- 
sents the form of an inverted bottle. The great length of the pygidium will serve as a 
character to separate 7. ampullaceus from all the other maculate species.
