above the fir forests and on the ridges. It was also found gener- 

 ally distributed but in small numbers at the foot of a glacier, 

 in wet spots covered with green flowering plants and just above 

 timber line on ground covered with volcanic ash in which scat- 

 tered and thin dry grasses grew. 



After dark individuals could be found in the dew-covered 

 grasses, scarcely able to move, their bodies ice cold. 



Melanoplus calapooyae 27 new species (Plate XVII, fig. 8; plate XVIII, 

 fig. 8.) 



Scudder unfortunately included under his Melanoplus validus 

 material referable to this species. 



The present species is clearly the optimum development in the 

 Saltator Group, both as to size and specialization. Nearest 

 relationship is shown to M. validus Scudder, which species occurs 

 in southern Oregon. This is shown by the male cerci, which are 

 of a similar type, though having reached a higher degree of special- 

 ization. 



From Scudder 's species calapooyae further differs in the larger 

 size, more robust form, male supra-anal plate with distal narrow- 

 ing portion fully as long as the proximal portion and color of 

 male caudal tibiae, which are yellowish with a pink tinge. 



In the form of the male supra-anal plate nearest agreement is 

 with the Shastan M. ascensus Scudder, this plate in the present 

 species being only slightly more elongate, with disto-lateral 

 sculpturing heavier. 



Type. — cf ; Divide, Calapooia Mountains, Lane County, Ore- 

 gon. Elevation, 1400 to 1600 feet. August 11, 1909. (Rehn 

 and Hebard.) [Hebard Collection, Type no. 557.] 



Size large, form robust for the group. Vertex and frontal costa as in validus, 

 much as here described for M. bernardinae. Eye slightly less than twice as 

 long as infra-ocular sulcus. Pronotum with medio-longitudinal carina dis- 

 tinct on metazona, subobsolete on prozona (in the series varying from obso- 

 lete to weakly defined in this section); sulci distinct, the principal sulcus 

 deep; caudal margin of disk weakly obtuse-angulate produced. Proster- 

 nal spine rather elongate, slender, tapering very weakly to the bluntly 

 rounded apex. Tegmina very slightly longer than pronotum, moderately 

 overlapping, broad lanceolate, with apices rather sharply rounded. Furcula 



27 The Calapooya Indians once inhabited the mountains which bear their 

 name and from which the present species is known.
