 color that characterized all the Salida specimens except one which was 

 colored similar to the Sedalia specimen.

One male, one female. Delta July 13. 



These specimens are unusually brachypterous, the elytra covering 

 but little more than half of the abdomen. The female is also smaller 

 than usual, but otherwise both specimens are typical. The posterior 

 tibiw are varia))le in color, those of the female greenish yellow with 

 a pallid subbasal annulus, while those of the male are testaceous 

 merging into pale reddish on the basal third. The measurements of 

 these two specimens are as follows: 



Length of bod}", male and female, 16 mm.; antennte, male, 5 mm.; 

 female, 1 nun.; pronotum, male and female, 3.5 mm.; elytra, male and 

 female, T mm.; posterior femora, male, T.5 mm.; female, 8 mm. 



97. MELANOPLUS ALTITUDINUM Scudder. 



Pezotettiv altitudmum Scudder, Proc. Bost. Soc. Nat. Hist., XX, 1879, j). 86. 

 Melanoj)lus hiironi Blatchley, Psyche, VIII, 1898, pp. 195, 196. 



Seven males, eight females, Pine Grove July 18, at the head of a 

 side gulch nearly a thousand feet above the town. Also one pair from 

 Pikes Peak July 21, one female above Boulder June 9, and one male 

 above (xolden June IT. 



The elytra of these specimens are somewhat variable in length, in 

 the male sex varying from 4.75 to 6 mm. There are several speci- 

 mens of this species in the United States National Museum named by 

 Dr. Scudder, and the male tegmina vnvy from 5.5 to 9.5 mm. and thei 

 female tegmina vary from 7.5 to 11 mm. in length. But these highen 

 nK^asurements seem exceptional, the usual length of elytra being about 

 t) mm. in the males and 7 mm. in the females. Types of JI('/<(/toj)lus 

 h'uroni Blatchley are in the National Museum and seem to be identical 

 with specimens of (ilt'dudinHm from various localities in the West. It 

 is not clear why Dr. Scudder placed this species in the Borckli serie;- 

 of the genus, as it surely does not belong there.
