what species of beetle is this?

Both are longhorns (Cerambycidae). Looks like they are in the Genus Prionus, or closely related.

Where are you located?

The second one is a male of Prionus (Neopolyarthron) imbricornis.

''are you kidding me that the first picture is a male of Prionus (Neopolyarthron) imbricornis?''

- You're meaning the second picture .

''I was asking the identification on a different bug site but no one knew what species my little male was and before I got here he died. so sad.''

- A good reason to ask for help more on insectnet than on other sites .

''Does anyone know how to attract and or a find male Prionus (Neopolyarthron) imbricornis? I randomly found the first one on my back window at night.''

- Put a strong light at your garden : Prioninae fly at hot evenings and are attracted to lights oftenly.

No, this pictured specimen here is a male of Prionus imbricornis. The female of this species is the 'huge' beetle you showed in your other post.
''and i was thinking what if I put them female out in a cage near a light at night and see if it attracts a male. Would that possibly work?''

- Yes, it could work, as a male could have been attracted by the female's pheromone. If you want to catch many males, best is to use pitfall traps baited with female Prionus pheromone, as shown here:

But the most simple is to put a strong light close to the place you collected these specimens. This way you will catch specimens of both sexes also, not only males !

But, take into account that, even if you will manage to catch many pairs and to mate them, the larvae of this species feed in the roots of fruit trees (taking years to develop), and this makes it too difficult (if not virtually impossible) to breed them successfully. On the other hand, Scarabaeids (e.g. Osmoderma) are much easier to breed as their larvae feed in the soil of trees.
