380 NOETH AMEKICAN MELANOPLI (ORTHOPTERA) 



of the tergite, the projecting portion feebly widening proximad 

 and twice as long as broad. Supra-anal plate shield-shaped, 

 distinctly longer than proximal width, medio-longitudinal sulcus 

 deep in slightly over proximal half, a short coarse carina on each 

 side of apical portion. Cercus of only moderate size, proximal 

 half slightly narrowing, shaft there bent dorso-distad and showing 

 extremely slight widening to the truncate apex which has the 

 disto-dorsal angle more strongly rounded and more produced than 

 the disto- ventral angle. Penis very broad and heavy, with two 

 broad erect convoluted plates cephalad before which are two 

 nearly adjacent erect aciculate processes, each of which proximad 

 has a very delicate rounded flange on its outer margin. Sub- 

 genital plate with a very low blunt apical tubercle feebly sug- 

 gested. 



Length of body 19., length of pronotum 4.7, caudal width of 

 pronotal disk 3.7, length of tegmen 3., length of caudal femur 

 9.2 mm. 



General coloration light ochraceous buff, occiput and dorsal 

 surface of pronotum sayal brown (a light brown), tegmina slightly 

 darker. A very broad unbroken postocular bar, all but ventral 

 portions of pleura, large areas laterad on abdominal tergites 

 (which decrease in size on each tergite and are extremely small on 

 the distal tergites) and apices of cerci blackish brown. Eyes 

 warm sepia. Antennae mikado brown (more reddish). Caudal 

 femora with two bars of dark brown dorsad of which the second 

 is heaviest, these extend on the external pagina as broad oblique 

 suffusions reaching only slightly below the median line, apices 

 mikado brown, ventral and internal surfaces light ochraceous 

 buff. Caudal tibiae light ochraceous buff tinged with pink. 



This specimen was on a steep slope where, when disturbed, it 

 had jumped out of an area thickly covered with sage brush onto 

 a slide of bare rock fragments. A single female only was seen in 

 addition, but most of our time was occupied at this locality in 

 collection a series of lemhiensis here described, as we did not then 

 recognize the present insect to be undescribed. 



Melanoplus salmonis new species (PL XXVI, figs. 7 and 8) 



This remarkable species in general appearance and marking 

 shows close resemblance to artemisiae Scudder, in which species 

 and the allied lemhiensis here described, however, the caudal 

 tibiae are pale glaucous; in the present species yellow buff tinged 

 with pink distad; in the other species of the Montanus Group 

 richer pink.
