MORGAN HEBARD 149 



The penis may sometimes appear to be of a strikingly dis- 

 tinctive type when such is actually not at all the case. Nor- 

 mally (except in ascensus calapooyae) the cochleate dorsal 

 lobes of this organ stand erect, with their convex surfaces 

 attingent and their concave surfaces directed laterad, embrac- 

 ing the acute apices of the ectoparameres. For some reason 

 rotation has apparently taken place in a very few specimens 

 (two of three males of saltator from Crabtree, Oregon, and 

 three males of atypic ascensus ascensus from Satus Pass and 

 Cliffdell, Washington) and in these the dorsal lobes have moved 

 in such a way that their (normally) cephalic margins are attin- 

 gent and mesad, their concave surfaces facing cephalad (simi- 

 larly embracing the apices of the ectoparameres) and their 

 convex surfaces facing caudad. Strange to say, this is the 

 normal position for these lobes in ascensus calapooyae. 



At present I feel that two species should be recognized, one 

 of which divides into three geographic races. 



Melanoplus saltator Scudder (PI. X, fig. 1.) 



1897. Melanoplus saltator Scudder (in part), Proc. U. S. Nat. Mus., xx, 

 p. 261, pi. 17, fig. 8. [ $ , 9 : Portland (type locality) and Oregon 

 City, Oregon. 2 ] 



The synonymy of M. algidus Scudder, described from Mary's 

 Peak, Oregon, was established by Fulton in 1930. Material of 

 this species was incorrectly recorded in the series described as 

 ascensus and as validus by Scudder in 1899. 



The following material is before me. 



Oregon: Portland, 53, 2$. Council Crest near Portland, 183, 13$, 

 3 juv. ?. Mount Tabor, 33, 3$. Clackamas, 13, 2$. Forest Grove, 

 26 3 , 18 2 . Salem, 19 3 , 5 $ . Turner, 3 3 . Crabtree, 3 3 . West Albany, 

 7^,5$. Corvallis, 3 3 . Philomath, 2 3 . Mary's Peak, 25 $ , 4 9 • Alsea 

 Mountain, 1 $ . Eugene, 4 3, 2 $ . 



In these specimens the caudal tibiae are dull bluish glaucous 

 to buffy in the males, the same or pink in the females. The 

 more sudden and more decided marginal convexity distad on each 



2 The male from Soda Springs, Washington, is here discussed under the 

 atypic material of ascensus ascensus. The female from Loon Lake, Wash- 

 ington, was placed under indigens digitijer with a query though definitely 

 as representing that species by Hebard in 1936.
