Elongate body and legs, with forward slanted face. Usually has a dark dorsal stripe. It can be very similar to the congener Mermiria bivitatta, but M. bivitatta lacks the dark dorsal stripe on the head and pronotum. M. picta also has lateral ridges on the pronotum and the lack of a white streak at the base of the wings. Another species that may seem similar is the Bunch Grass Locust (Pseudopomala brachyptera), but that species usually has very short wings.
Grasshoppers of the Western U.S. does not have Factsheet for M. picta, but it does have a Factsheet for M. bivittata which explains how to distinguish the two species: http://idtools.org/id/grasshoppers/factsheet.php?name=13203
