360 NEW NOETH AMERICAN MELANOPLI (ORTHOPTERA) 



median limbs suffused sayal brown, tinged with greenish distad. Caudal 

 femora sayal brown in exposed portions, with two weakly denned bars of 

 bister, which beginning on the dorsal portion of the internal face run across 

 the dorsal face, being very weak on the external section and, with a more 

 proximal suffusion, make up the usual color pattern of the pagina, as found 

 more conspicuously developed in other forms of the genus; ventral and 

 ventro-internal portions barium yellow. Caudal tibiae with external sur- 

 face whitish, heavily overlaid with niagara green, other surfaces niagara 

 green, except in brief proximal whitish portion; spines white in proximal 

 portions, black distad. 



The series shows little color variation from the type described. In some 

 the coloration is more generally sayal brown, in others bister with pale areas 

 of exposed surface of caudal femora contrastingly cinnamon. The Crest- 

 line series shows the weakest color pattern of all, the general coloration being 

 tawny-olive. 



Specimens Examined: 54; 16 males and 38 females.

In the Spring Mountains this insect occurs through the zone 

 of juniper and pinyon and well up into the zone of the bull pine 

 (Pinus ponder osa douglasi). It reached its greatest numerical 

 abundance, being moderately numerous and widely distributed, 

 in the sparse grass and low green plants growing on pebbly soil 

 at 7000 to 7200 feet, where the junipers and pinyons also reached 

 their optimum development. At Crestline it was very scarce, 

 the specimens being found singly and widely scattered, occurring 

 in areas where a low yellow-flowered composite and sage brush 

 grew among the scattered junipers and pinyons. The single 

 individual taken at the foot of the Ruby Range was found under 

 conditions similar to those at Crestline. 



Bradynotes albida new species (Plate XVI, figs.* 2 and 3.) 



This interesting species shows nearest relationship to B. ex- 

 celsa Rehn (plate XVI, fig. 4), differing in a number of color 

 features and particularly in the more whitish general colora- 

 tion, the subobsolete principal transverse sulcus of the pronotum, 

 carinate abdomen and distinctive type of male cerci. 



These two species are of broad form, but by no means as broad 

 as the other species of Bradynotes. They inhabit the upper
