Mansour, I agree with you that your first four specimens are Carabus as well as the sixth specimen. I am fairly positive that the fifth specimen is not a Carabus (though I can't suggest what genus it is) and the last two specimens are not Carabus, but seventh is a harpaline, possibly a Harpalus species; and the eigth specimen is probably a Brachinus sp. Someone with greater taxonomic acuity can help you further.
Hi Mansour, I agree with Dmitry, precise identification is almost impossible, but I have the same identification. Carabus 4, providing that the preparation did not alter it, seems to be a helicophagous species, having some cychrus-like mandibles. Do you hav better photos?
