Abstract
Several of the “subspecies” and “forms” of Acrididae listed but not named by Brooks are discussed and a subspecies of Melanoplus packardii is named. Subspecies of Melanoplus sanguinipes and Pardalophora apiculata proposed by Brooks are not recognized. Trimerotropis longicornis E.M. Walker is removed from synomymy with T. campestris McNeill, as the names apply to different taxa.
