26 ILLUSTRATIONS OF UNFIGURED LEPIDOPTERA. 



On August 3d, I continued on for nine miles and pitch- 

 ed our tents. The high altitude of the entire country 

 thus far passed prevents any heavy growth, the limit of 

 the timber line being constantly in our vicinity. The 

 Lepidoptera found here were the same as those taken at 

 Bella Vista, two days out from La Paz, and were not as 

 plenty. 



We remained here a week, and on August iSth contin- 

 ued our journey over the undulating grass covered country, 

 camping that night in a barren district and were forced 

 to remain there for three days, owing to heavy continuous 

 ram with thunder and vivid lightning. Our tent was partially 

 upset by the high wind during the night, and the dis- 

 comfort caused will be readily appreciated by anyone used 

 to camping. Almost everything was soaked; cooking, owing 

 to lack of wood and the grass being wet, was impossible, 

 so we ate cold stuff and tried hard to be cheerful. 



On Monday, August 2ist, the rain ceased and we had an 

 opportunity to dry. We travelled only until 3 p. m. and 

 again made camp, rain threatening. A few drops only, 

 however, and the next morning we reached the edge of the 

 ridge and looked down upon a welcome sight; long valleys 

 densely wooded, with hills here and there all covered in a 

 tropical growth. We had indeed, at last crossed the high 

 range. It seemed as if we were looking down into a huge 

 crater filled with steam. The view was grand, awe-inspir- 

 ing. The road down into the valley was a horrible, tor- 

 tuous, continual zigzag, narrow, rocky, and very slippery. 



Near the bottom, we camped about a week, near a small 

 stream. We were five days from Cochabamba, at the en- 

 trance to the valley called Chara-playa. 



Butterflies were neither plenty nor varied. 



We left here and continued north for a day, having much 

 difficulty in getting our mules through the narrow trail, and 

 stopping many, many times, to cut away fallen timber, some- 

 times being obliged to cut new trails around the heavier 

 wind falls.
