after corresponding with the photographer
and Steven Lingafelter, the consensus is that this is T. agave
Antennae attaining the apical ¾ of elytra or greater; pronotal pubescence sparse on frons and pronotal disk ---- T. agave

versus T. armatum
Antennae attaining basal 2/3 of elytra or less; integument of head, legs, and pronotum black; pronotal pubescence black, dense on frons and pronotal disk ---- T. armatum

Tragidon armatum post
The two pictures are of what I believe to be a male and a female specimen. They were reared from the same group of larval grubs which pupated in April and emerged around May 1st. I believe that they are the same species, just a male and a female.

These don't look like the same specimen
If these pics are of different specimens, please unlink them. Also, I think your ID of T. armatum is correct.
