JNTOMOLOGICAJ^NEWS^ VOL. XLII. MARCH, 1931 No. 3 The Races of Diapheromera veliei (Orthoptera, Phasmidae, Heteronemiinae). By MORC.AN HEBARD, Philadelphia, Pennsylvania. Recently in our studies of the Orthoptera of Kansas we found that Diapheromera I'dici Walsh, occurred in its typical form over that entire State, its maximum abundance being reached in the central Great Plains. It is apparently less hardy than Dia-pheromera fcinontta (Say) as its known northern limits are Lake Hendricks, South Dakota, and Julesburg, Colorado, while toward the foot of the Rocky Mountains in Colorado (except probably in its southern portion) it disappears, this probably due there to the greater elevation and consequently more boreal environment of the plains. To the south we have it typical as far as Stillwater, Oklahoma, Dalhart, Texas, and Vaughn, New Mexico, and it reaches west-ward over the lower divides of the Rockies as far as Albuquerque, in the latter State. Further south in Texas and New Mexico, however, we find it supplanted by a geographic race and study of the literature convinces us that that race must bear the name Diapheromera veliei mesilhina Scudder. The following data lead to this conclusion. DIAPHEROMERA VELIEI MESILLANA Scudder. 1901. Diapheromera uicsillauu Scudder, Psyche, IX, p. 189.

[ 5 , $ ; Texas. 1 ] Scudder described mesillana from immature males and, though difficult to associate specifically, we have sufficient such material to be satisfied that the species represented is the same as that 1 The specimen recorded from New York was either mislabeled or repre-sents a distinct species. 65
