1902,] NATURAL SCIENCES OF PHILADELPHIA. 717 NOTES ON THE ORTHOPTERA OF NEW MEXICO AND WESTERN TEXAS BY JAMES A. G. REHN. The great part of the material on which this study is based was collected for the Academy in the spring and early summer of 1902 by Mr. H. L. Viereck and the author. All specimens from Ysleta and El Paso, Tex., and Alamogordo, Cloudcroft and Highrolls, N. M., were thus collected. A general geographical and biotic study of the localities in the Sacramento mountain region, New Mexico, will be published later in these Proceedings. Specimens belonging to the United States National Museum were examined in conjunction with the Academy material, and such specimens are designated in this paper by the initials of that insti-tution. The loan of this material was secured through the kind-ness of Mr. W. H. Ashmead. The fine recent work by Messrs. Scudder and CockerelP on the Orthoptera of New Mexico has proven of great value in studying this collection. Family BLATTIDu^. Homoeogamia subdiapliaiia Scudder. Ten males, one female. Alamogordo, Otero county, N. M. April 11, May 5 and June 6 and 7, 1902. Highrolls, Otero county, N. M. June 8, 1902.
