collecting" at dltitiules higher than common was in the National Park, at 

 an altitude of 8,500 feet. Again I saw Parnassius smintheus, that gor- 

 geous insect of the alpine realm. I gave chase, and after landing the 

 prize in the net sank to the ground exhausted and gasping for breath. 

 In the Mission Mountains of Montana I have had many a happy day 

 among the peaks at 9,500 feet and lower. This short range has some of 

 the most beautiful mountain scenery in the world. Many of the insects 

 taken are recorded in this work. I have collected in the Swan range, 

 and in the main range of the Rockies, at altitudes up to 10,000 feet. In 

 northern Montana timber line is 9,500 feet. In Colorado it is about 

 11,500 or 12,000 feet. These two elevations in the different localities will 

 probably have about the same flora and fauna, or at least similar condi- 

 tions. Never have I found insects so abundant as at Seven Lakes on 

 Pike's Peak, and rarely are they abundant. Quite frequently but a single 

 specimen is captured, often but a few. For several years we have an- 

 nually made the ascent of MacDougal Peak in the Swan Range, whose 

 elevation is approximately 7, GOO feet. On these occasions I stay behind 

 to see that all are going down safely. I always loiter on the summit or 

 along the long ridge, collecting a few Lycaenas, Argynnids, Pierids, or 

 Phyciodes. 



If the butterfly students of Montana will seek healthful exercise, 

 magnificent view of snow-clad mountain summits and peaceful wooded 

 valleys, with a catch of few but rare and very choice insects, let them 

 ascend some high peak in July or August, seek a sunny slope of open 

 woods and abundant vegetation, and pitch their tents for a week. It will 

 add years to the latter end of life. M. J. E.
