280 NEW NORTH AMERICAN MELANOPLI (oRTHOPTERa) 



with margins brazil red, the remaining portion black with a claret tinge- 

 Caudal tibiae with dorso-proximal lobe strikingly salmon-orange; external face 

 buffy excei)t proximad, where it is deep bluish gray-green and narrowly dorsad 

 bluish gray-green; ventral face buffy; dorsal face nopal red, except briefly suf- 

 fused proximad with vandyke red ;^5 internal face similar but with intensity of 

 coloration not as great. The allotypic female is similar but not as brilliant, 

 while the dark areas are more extensive. The pronotal disk is mars brown, the 

 dorsal surface of the abdomen mars brown, except for a narrow medio- 

 longitudinal line and disto-laterad, where it is cinnamon brown. 



Specimens Examined: 19; 13 males and 6 females. 



Oregon: Big Meadows of the Deschutes River, eighteen miles southwest 

 of Bend. 



This series was collected, in Julj^ 1913, by C. H. Kennedy, 

 probably in the eastern edge of the dry pine woods, covering the 

 eastern edge of the Cascade Mountains, and given to W. T. 

 Davis. Due to Mr. Davis' generosity, the series is now divided 

 between the Davis and Hebard Collections and those of the 

 Academy of Natural Sciences of Philadelphia and United States 

 National Museum. The specimens, other than the type and 

 allotype, are designated paratypes. 



Melanoplus huporeus^*"' new species (Plate XXX, fig. 3; plate XXXI, fig 2.) 

 The present species belongs to the Marginatus Group, and 

 shows distinctly closer affinity to M. marginatus Scudder, than 

 to M. gracilipes Scudder. 



From the long-winged marginatus it differs in the slightlj' 

 heavier form, blunter vertex and broad oval tegmina, which 

 frequently have the immediate apex acute and sharply rounded, 

 but are never produced distad, with apex acute, to the degree 

 normal in the short-winged marginatus variety pauper Scudder. 

 In addition, males are readily separated by the form of the cerci, 

 which in marginatus (see plate XXXI, fig. 1) are shorter, with 

 apex truncate and strikingly inflated. In coloration the two 

 species are very similar. 



*^ The extent of this purplish portion varies slightlj' in the series. In the 

 type of pinguis the caudal tibiae are nopal red, slightly ixiler proximad on the 

 external face; in the allotype similar, but with a blackish green annulus below 

 the dorso-proximal lobe. In a very large series of that species from timber line 

 on Mt. Shasta, California, however, the tibiae are all bicolored, dark purplish 

 proximad and red distad. This indicates that the color of the caudal tibiae in 

 pinguis, and probably in related species, can not be considered of specific diag- 

 nostic value, as supposed by Scudder and used in his key, Proc. U. S. Nat. Mus. 

 XX, p. 81, (1897).
