Platte Can3-on. Collecting- was done up the canyon as far as a small 

 side gulch known as Mill Gulch, and up that <>-ulch for more than a 

 mile, as well as up other gulches for lesser distances. But most of 

 the Orthoptera were taken near the mouth of the canyon. But ten 

 species were taken here. 



Rlco^ Dolores County; altitude^ 8 J o7 feet. — Insects were very scarce 

 here, two hours' collecting resulting in but three species of Orthoptera 

 and practically nothing else. The Orthoptera were all alpine forms. 



fSat/'dfi, CJuifW County; nJtitade^ 7^,050 feet. — Two weeks were spent 

 here, including a couple of visits. Other duties prevented much time 

 being devoted to collecting Orthoptera, and nearly every afternoon 

 it rained, but still quite a number of good things were taken. By far 

 the most productive locality was the side of the large hill, called 

 Tenderfoot Mountain, just across the railroad from the station. 

 Here ^Eoloplus plagosus and Derotniema hiydeni occurred in luun- 

 bers. Lejnnis eymieus was also taken here, though not so numerous 

 and usually some distance farther up the hill. 



Sed(dla, Douglas County; altitude, 5,835 feet.- — This small town is 

 a few miles south of Denver, and is in a broad valley formed by the 

 foothills on the west and high mesas on the east. Collecting was done 

 across the entire valley, but only eleven species were taken. 



At the above localities over a hundred species of Orthoptera were 

 taken and the collections from Arizona and Texas bring the lumiber 

 up to one hundred and lifty-four. All are here mentioned, even if 

 only for the value attached to record of exact locality, })ut many of the 

 species are represented bv a considerable luunber of specimens and 

 thus usually furnish some notes of value on variation or distri])ution.
