Dr. R. H. Beamer has aided greatly in our studies in having 

 obtained permission to send us the type and allotype of this 

 species for examination, which specimens belong to the University 

 of Kansas. 



The penis is here figured for the first time. The species is 

 much more closely related to femur-nigrum than to any of the 

 others of the present group. 



Though the caudal tibiae are rich glaucous in all of the males 

 they are pink or glaucous in the females, as follows: Magdalena 

 Mountains, New Mexico, 6 pink, none glaucous; Alpine, Arizona, 

 2 pink, 5 glaucous; White Mountains, Arizona, 11 pink, 7 

 glaucous. Such dichromatism peculiar to the female sex is here 

 discussed under femur-nigrum Scudder. 



New Mexico: Magdalena Mountains, 9600 to 9900 feet, VII, 23, 1933, 

 (E. R. Tinkham; on eastern slopes among scrub oaks and grasses), 12 d 1 , 10 9 .

 Mountains eight miles west of Springerville, 9300 feet, VII, 25, 1930, (E. R. 

 Tinkham; four in meadows, twenty one on pine forest floor), 11 cf, 16 9.

Melanoplus magdalenae new species (PL XXV, figs. 2, 3, 4 and 5) 



This insect supplants M. snowii Scudder at higher elevations in 

 the Magdalena Mountains, just as truncatus Scudder supplants 

 femur-nigrum Scudder in the San Francisco Mountains. 



It is clearly nearest truncatus, the general coloration and color 

 pattern being very similar, the male furcula and cerci being 

 nearest those of that species but showing distinctive features. 

 The insect is distinctly less robust, the male with apex of abdomen 

 less enlarged, supra-anal plate much shorter, cerci tapering more 

 conspicuously in distal portion, penis with processes very differ- 

 ently shaped and subgenital plate with apical tubercle consider- 

 ably more prominent.
