I would have hesitated about whether this is S. rubiginosa or S. damnifica, except that the antennae are rather short for S. rubiginosa. The next photo shows the strongly raised median ridge of the pronotum, the wideness of the antennae, and other features that point to this definitely being S. damnifica.

Keys in literature often state that S. damnifica has antennae shorter than the head and pronotum together, and then proceed to show a photo in which the opposite is true. Actually it varies, but in females the wide slightly flattened antennae are usually about as long as head + pronotum or slightly shorter, and in males they are usually slightly longer than in females. They are longer in some populations than in others. Also, since the head moves in relation to the pronotum, the measurement is not an exact one, and in photos the antennae are often at an angle, making them look shorter than they are. In S. rubiginosa antennae are usually conspicuously longer and more slender (often near the length of the hind femur in males), not obviously flattened, but the same problem with perspective can occur in photos.

Both this and Melanoplus have the prosternal process/spur, but Schistocerca are usually bigger and have a slightly different shape. Also, this photo shows the underside of the thorax, where you can see that the "mesosternal lobes are longer than wide" (see the key on this site). I suspect this one is S. rubiginosa.
