Giglio-Tos gave the spiiiiilation of the two margins as eleven 

 to fifteen, but it is evident that in the material before him the 

 minimum was as low as eight and the maximum as high as sixteen. 

 With an intra-specific range in the number of spines on one 

 margin of from eight to twenty-one in the same sex, and from 

 eleven to twenty-one in individuals from the same locality, it is 

 evident that the number of spines is an extremely unreliable 

 specific criterion in this group. 



In his recent key to the species of this genus, Bruner^^ has mis- 

 interpreted this species, as he has placed it in a section of the 

 genus having the apex of the rostrum blunt, when as a matter of 

 fact it is chstinctly acuminate. The male of this species can be 

 immediately separated from the closely allied T. bihastatus Rehn, 

 from Corumba, Brazil, by the much shorter and less acuminate 

 subgenital plate.
