Grasshoppers of the genus Oxya, Serv., are well known to economic entomologists in India and Malaya as pests of rice and other crops cultivated under irrigation. An enormous confusion in systematics of the genus was responsible, however, for gross inaccuracies in records of these pests with regard to the actual species involved in each case. Indeed, no other species except O. velox has been ever recorded as a pest, so far as I know, simply because this was popularly supposed to be a most widely spread and common species, while the descriptions of it by different authors were sufficiently vague to enable one to apply the name to almost any species of the genus.
