During a brief stop of the train at Newcastle, I succeeded in captur- 

 ing a single specimen of this species in the dust beside the railroad 

 track. 



Hesperotettix speciosus (Scudder). 



Akron, Washington Co., Colorado, Aug. 24, 1 c^. 



The median carina of the pronotum of this specimen is deep maroon 

 piu-ple, which depth of coloration is almost equalled in a male from 

 Rocky Ford, Colorado. 



The specimen was beaten from tall weeds. 



^OLOPLirS Scudder. 

 .ffioloplus regalis (Dodge). 



Fort Morgan, Morgan Co., Colorado, Aug. 24, 1 d^. 



A single specimen was beaten from low bushy weeds growing densely 

 about a water tank. Vigorous beating for several minutes failed to 

 produce other specimens. 



.ffiloloplus chenopodii (Bruner). 



Antlers, Garfield Co., Colorado, Aug. 15, 11 d^, 14 9 . 



This series varies considerably in the intensity of the coloration, 

 some individuals being more ashy than others. 



The specimens were easily taken in spite of the cactus, in which they 

 invariably sought refuge, for their movements were slow and they could 

 jump but a short distance. The species was abundant. 



BRADYNOTES Scudder. 

 Bradynotes obesa (Thomas). 



Summit of first foothill behind hotel. Mammoth Hot Springs, Yellow- 

 stone Park, Aug. 5, 1 ? . Top of bare hill opposite DeviUs Kitchen, 

 Mammoth Hot Springs, Aug. 5, 1 c?, 2 ? . 



Although much time was spent searching carefully for specimens of 

 this species, two days' collecting resulted in but four specimens being 

 found. All were taken on the gravelly tops of the foothills where 

 vegetation was almost absent. Their color blended perfectly with the 

 soil and they appeared to rety on this as a means of protection. 



PODISMA Latreille. 

 Podisma dodgei (Thomas). 



Pike's Peak, Colorado, at elevations of 9,700 (Mountain View) and 

 10,200 feet, Aug. 20, 2 d", 1 ? . 



These specimens and the specimen of Hippiscus altivolus were 

 the only Orthoptera seen in the rather barren tract of stunted aspen
