14 ILLUSTRATIONS OF UNFIGURED LEPIDOPTERA. 



I met here five Americans who came to Bolivia in search 

 of gold, and besides finding them very companionable, they 

 gave me much assistance in various ways. I should also men-

 of a snow storm. After passing the ridge, the snow turned 

 to rain, and we began our descent to the valley. We passed 

 a few stone houses in the yards of which Indians were un- 

 loading mules in preparation for the night. At one of these, 

 a one-story building, called " The Pongo," we passed the 

 night after a good supper of soup, steak, eggs and boiled 

 milk. 



At 6.30 the next morning, we were again on the road. 

 The perpendicular sides of the narrow valley still dripping 

 from the previous day's rain and the early morning fog. As 

 the day advanced, the sun, first brightening up the highest 

 points, gradually crept down the sides of the valley, the
