You give no indication of size or location or habitat.
It looks like a Ground Beetle Family Carabidae. However this is an extremely diverse group. If you want to narrow it down further, maybe you should take or send your specemin to the museum for an ID.
I think the first one is Loricera pilicornis - the hairs on the antennae help in its diagnosis I believe. The second maybe a Nebria species.
Thank you both so much for your help, it really is appreciated.
