NATURAL HISTORY BULLETIN. 



a great part of the researches were carried on at a time when 

 the writer was in the emplo}' of the Railroad Company and 

 had little leisure for observations on the fauna. The collec- 

 tions thus made during the season of 1887 were supplemented 

 a 3'ear later by additions made on a trip undertaken for the 

 purpose and represent between them the fruits of his first 

 experience in the west. 



Of the localities which furnished specimens, Coolidge and 

 Gallup are in New Mexico, The Needles is in California while 

 all the remainder are in Arizona. Coolidge lies at an altitude 

 of 6975 feet 1 above sea-level, on the western slope of the great 

 Continental Divide, and is situated in a pass with high hills on 

 each side. Close to the station there are no trees, the vegeta- 

 tion consisting chiefly of Artemisia^ and other scrubby brush, 

 intermixed with stunted junipers, but the adjoining heights are 

 covered with coniferous growths. A few miles to the west- 

 ward lies Gallup, which owes its importance to the coal fields 

 underh'ing the surrounding region and here, though the alti- 

 tude is less by 500 feet, there is a better growth of pines than 

 at Coolidge. At neither point is any permanent stream of 

 water present. 



Holbrook lies on the Little Colorado River in eastern Ari- 

 zona, 5047 feet above the sea-level. There is no coniferous 

 growth here, but in the river bottom are a few cottonwoods in 

 groups of various size. Some collecting was done here as 

 early as April, which may account for the presence of certain 

 species not recorded from the other localities in this valley. — 

 Hardy, which is a few miles to the westward and 137 feet 

 lower, and Winslow still farther west with an altitude of 4825 

 feet. The last place proved a very good ground for insect 

 hfe, the flats along the Colorado Chiquito being especiall}' 

 productive of interesting forms, owing perhaps to the abun- 

 dance of underbrush and to the fact that the natural growth of 

 Cottonwood had not been interfered with. 



Leaving Winslow, the track rises gradually until at Walnut
