The following- paper deals with three separate ('ollections: (1) a 

 large collection fi'om Colorado, including a few from just across the 

 line in New Mexico, made }\v Dr. H. G. Dyar and myself during the 

 months of May, June, July, and August, 1901; (2) a small collection 

 made in Arizona, mostly at Williams and Hot Springs, b\' Messrs. 

 Schwarz and Barber during the summer of 1001; and (3) a small col- 

 lection made by the writer in Texas in June and July, 1902. This 

 material forms part of the collection of the U. S. National Museum. 



The Colorado collection, which furnishes material for the greater 

 part of this paper, but partially confirms the result reached by 

 Dr. Dyar regarding the life zones of that State as recently described 

 by him" — that is, that there are four faunal regions in Colorado: 

 prairie, foothill, alpine, and western slope. The orthopterous faiuia 

 indicate the first three zones only, which are in most cases ([uite 

 sharply defined, but there are a numl)er of species that occur in two 

 or more of the zones. The line between the prairie and the foothill 

 faunas is exceedingly well defined at some places, while at other places 

 the transition from one to the other is more gradual. 



The primary aim of the Colorado expedition was to woi'k out the 

 life history of Lepidoptera, and not to collect Orthoptera, and in conse- 

 quence it was not possible to visit all parts of the State. Therefore 

 the range worked over is not extensive and does not include places 

 inaccessible by rail. A few specimens from Middle Park were pur- 

 chased from E. J. Oslar, a professional collector of Denver, and are 

 included in this pajjer. 



The various localities visited by the writer in Colorado, their alti- 

 tude, location, and notes on the vicinity are given in the following 

 alphabetical list: 



Baileys, Pari: County; altitude, 7,7Ufeet.—Th\H place is some miles 

 up the Platte canyon. One day only was spent there and l)ut nine 

 si)ecies of Orthoptera were taken.
