Through thecourtesy of Dr. George E. Wallace, Carnegie Museum, we haveexamined a rather long-winged male of bilituratus bilituratus taken bythe late Dr. Walter Sweadner, Aug. 9, 1932, at an altitude of 7,200feet, imbedded in the Sperry Glacier, Glacier National Park, further details are available. In New England bilituratus bilituratus occurs from the seashore tothe summits of the highest mountains (Morse, 1920). Some altitudeson the labels of specimens examined are as follows: Junction of Moose 24 PROCEEDINGS OF THE NATIONAL MUSEUM. GRASSHOPPERS—GURNEY AND BROOKS 25 Pass-Hope Highway and Moose Pass-Kenai Highway, Alaska, 1,800ft.; Signal Peak, Wash., 5,000 ft.; Wasatch Mts., Utah, 7,400 ft.;Chaffee Co., Colo., 8,000-8,500 ft. The classic report on the effects of temperature and moisture onthis grasshopper is by Parker (1930). MacCarthy (1956) dealt withthe correlation between adult populations and weather factors inSaskatchewan. Criddle (1918, 1924) and Shotwell (1930) are among those who havedescribed the egg pods of bilituratus bilituratus, and Can trail (1943)gave a detailed account of the way the ovipositing female preparesthe hole in the soil. Parker (1930) recorded one caged female whichlaid 15 egg pods, and the average for 30 females observed by him pods. Other data on egg production were presented by Pfadt(1949) and Smith, Handford, and Chefurka (1952). In laboratorycages, using material from central Saskatchewan, Pickford (personalcommunication
