representatives of the species from northern Arizona. This is the first 

 record of the species from Texas. 



Melanoplus altitudinum (Scudder). 23 



Two females of this species were collected in James Canyon, Cloud- 

 croft, July 14-15, one being from the overgrown slope of the canyon, 

 the other from a weedy spot at the mouth of the canyon. The indi- 

 vidual from the slope of the canyon is somewhat smaller than the other 

 specimen. 



The previous New Mexican records of the species are from northern 

 New Mexico (Scudder), Taos Peak, 13,000 feet (Scudder), ridge between 

 Sapello and upper Pecos River (Scudder, Cockerell) and Cloudcroft 

 (Rehn). 

 Melanoplus feuiur-rubrum (De Geer). 



A series of seven males and seven females of this widely distributed 

 species were taken in cultivated ground at Albuquerque, September 

 14, a single male also being collected at El Paso, July 11, in bottom- 

 land along the Rio Grande. 



Melanoplus calidus Scudder. 



One of the most characteristic grasshoppers of the mountain meadows 

 and of underbrush in certain portions of the forest-land around Cloud- 

 croft is this striking species. Scudder originally described this 

 insect from Oilman's Ranch, Eagle Creek, White Mountains, New 

 Mexico, at an elevation of 7,000 feet; Scudder and Cockerell later 

 recording it from the South Fork of Eagle Creek. 



The species was found to be plentiful on July 

 14 and 15, although in the morning before ten 

 o'clock it was very hard to find. The series 

 taken consists of twenty-nine males and twenty 



femaleS - . Fig. 15. -Melano- 



In size there is great uniformity in the male plus calidus 



sex and but little variation in the female, and then Scudder. Dorsal

with Scudder's measurements the specimens are 



generally smaller, picked individuals giving measurements as follows: 



23 The great difficulty of separating some of the brachypterous species of 

 Melanoplus from representatives of the genus Podisma and the close resemblance 

 existing between Melanoplus altitudinum and Podisma dodgei was responsible 

 for an erroneous determination made by the senior author (Proc. Acad. Nat. Sci. 

 Phila., 1904, p. 571). The specimens from Raton, New Mexico, and Prescottand 

 Copper Basin, Arizona, there referred to M. altitudinum, are really Podisma dodgei, 

 as a careful re-examination of all the available material in the two species shows. 

 A series of Coloradan P. dodgei and Wyoming and New Mexican M . altitudinum 

 have been used for comparison.
