THE LEPI'DOPTERIST 95 



hard climb. In a previous trip in August I saw many 

 Oeneis semidea, Say, in this same spot. Watching the 

 clouds carefully to see that we did not get caught in 

 a snow squall we made our way over rocks and around 

 rocks towards Tuckerman's Ravine, which was a coup- 

 le of miles away. We were now in what is known as 

 the "Alpine Garden". The only flowers visible were 

 this small bush with pink flowers. A great snowbank 

 lay in one section, covering an acre in extent, but be- 

 yond this the mountain was free of snow. We noted 

 a webb in between two rocks with the spider in the 

 center. This seemed unusual at such an altitude and 

 in the face of such high winds. Suddenly we saw a 

 tattered specimen of Papilio turnus blown up the 

 mountain and over our heads, but in such a gale it was 

 impossible to secure it. My attention was attracted 

 to a brown crab spider trying to hide under a rock, 

 and after some effort succeeded in catching it. This 

 later proved to be a great rarity, only the type being 

 known, which was taken by Mr. J. H. Enerton about 

 1875. 



We approached Tuckerman's Ravine with dread, 

 for if it was filled with snow we would have to retrace 

 our steps back the way we came, and it was then about 

 3 o'clock in the afternoon. As we neared the brink 

 we could hear the sound of running water and de- 

 cided to take a chance and go down. Excej)t for one 

 or two banks the snow was pretty well melted, making 

 it possible to carefully pick our way to the bottom ; 

 we had to be very careful for a slip meant a fall of 

 1000 feet. The "arch" as it is called, extended about 

 two thirds of the way to the top and as we descended 

 I noted the false hellelon had grown about a foot in 

 height. Later in the season, in August, this is the 

 place where Eupethecia cretaceata Packard is found. 



It took us nearly an hour to descend, and we found 

 many of a species of black hairy spider beneath the 

 small stones which we overturned. At the bottom the 

 birch trees were also three feet high and were just 

 beginning to leave- We proceeded along a mountain 

 stream, in and out between boulders for another hour,
