insects of many varieties all about us — Argynnids, Pamphilas, 

 Lycaenas, Satyrids, Ccenonymphas, etc. Most of the species, how- 

 ever, were the same as those common to Utah. Soon, however, 

 the ground became higher and on crossing one of the high 

 knolls a gray butterfly sprang up, almost resembling a grasshop- 

 per in its quick motions'. It darted about and then dropped into 

 the grass. Others of the same kind were soon started and after 

 some careful maneuvering my first Hipparchia ridingsii was 

 safely landed in the cyanide jar. On these grassy round-topped 

 hills many of this species were found, but the sport much resem- 

 bled jack-snipe hunting, and I longed for a gun and some harm- 

 less kind of ammunition with which to pepper the wily insects ; 

 ridingsii often lights on bare spots of ground, but the gray color 

 of its wings blends so well with the soil and dry grass that it is 

 very hard to see. Its habit of folding the primaries within the 

 secondaries and occupying the smallest possible place and even 

 tumbling over on one side so as to almost lie flat on the surface, 

 resembles C. chryxus. Like that species, also, it not infrequently 

 alights on bare rocks. This species was not seen elsewhere until, 

 on the road from Livingston to Yellowstone Park, one darted up 

 in front of my horse only to alight in the dust and formed so 

 tempting a prize that I dismounted and captured it. 



Soon we came to a deep, well-wooded gully, probably one- 

 quarter mile in width, and, while crossing this, a little brownish 

 black insect started up from a small grassy glade, and after a 

 rapid chase over logs and brush the first specimen of Cceno- 

 nympha haydenii was being examined. 



While dinner was preparing, a little search near camp resulted 

 in the capture of several more haydenii. After dinner, with our 

 friends, the ranchers, we collected on the higher ground back of 

 camp and secured a number of fine insects. Argynntds^were 

 probably most abundant, and the most common species was 

 eurynome. A few leto were taken and examples of several other 

 species or varieties. 



During the afternoon we worked our way back to Beaver, col- 

 lecting en route, and on passing their metroplis again spent some 

 time with the Hipparchias. 



Mr. Wood and his men urged us to make our home at their 

 camp while in the vicinity. Never has it been my fortune to be 

 more generously entertained or made so welcome among strangers
