clothed, but bare of tree or shrub (the ever-present sage-brush 

 •excepted) and parched by the sun from July until Winter. 



What limited amount of shrubbery does occur is also confined 

 to the water-courses. We have our native choke-cherry, wild- 

 rose, plum, willow, snowberry, buffaloberry, greasewood and 

 sagebrush, a meagre list indeed, when compared to the hundreds 

 of shrubs and bushes abounding in most eastern localities. All 

 vegetation without it may be grasses and wild flowers occurs 

 with us in but the most limited variety. We have no woods, no 

 swamps, no hedges. What wonder then that the entomologist's 

 hopes are saddened as he realizes that a corresponding dearth 

 exists among his favored and busy tribes! 



I wonder who can recount the exact number of Papilios he has 

 seen during three years past ? It is my good (?) fortune to have 

 seen just fourteen during that period. In the season of 1891 I 

 saw but one, it was one of the Tur7ius group, probably rutulus 

 or daunus, its rapid flight, however, baffled detection. In May 

 of this year while returning from our ranch, on horseback, a dis- 

 tance of about one hundred miles, I saw another of this same 

 group, but was unable to capture it. During this trip, also, I 

 counted nine zolicaon, only one of which was not in rapid flight 

 across country; this one, a female, was depositing her eggs on 

 our native wild parsnips, and I caught her easily, and obtained 

 some twenty eggs, which I reared on cultivated parsnips in my 

 garden. The only other Papilio seen this 5*ear was one related 

 to zolicaon, but had none of the prominent show of yellow so 

 characteristic of that species when on the wing. What it may 

 have been I cannot say. 



Finally, two specimens of zolicaon taken on the summit of 

 Signal Butte, near this city, on May 30, 1892, complete the 

 number. 1 cite my experience with the Papilios to give a gen- 

 eral idea of the scarcity of species occurring here. 



A few species of Colias, Pieris, Euptoieta, Phyciodes and Ly- 

 ccBna occur here, however, in sufficient abundance not to be called 

 rare. There exists an unusually localized distribution among 

 most species here, which doubtless results from a similar localiza- 

 tion of the food-plants, many of which are to be found only near 

 flowing springs or other sources of moisture. The Satyrids, 

 Pamphila, and other prairie varieties, however, may be met with 

 in country of almost any character, as also may such ranging
