One male found at San Antonio, Texas, by Mr. Haldeman. Shorter and 
stouter than most species of the genus, with the antennae slightly moniliform, 
and hardly reaching the base of the thorax ; the labrum is piceous and slightly 
emarginate ; the emargination of the mentum is nearly square, and the medial 
tooth obsolete ; the ligula is dilated and truncate, as in the other species with 
inflated paraglossse.
