 Cecentromenus, Brunn. In the synopsis of the species of Bliastes given by Brunner v. 

 Wattenwyl it would follow B. scabrifrons and B. lineatifrons.

This species closely resembles B. lineatifrons, Brunn., from Honduras, but differs 

 from it in the spinose genicular lobes of the hind femora, a character bringing it into 

 the second group of the genus, near B. atrifrons, Brunn.
