is always overhung by clouds: it is a region of very heavy and ahuost 

 constant precipitation ; during the time when the collection was made 

 it rained almost continuously every day. Trees are abundant and 

 thickly draped with a dense covering of moss, with an abundance of 

 ferns and vines and many orchids, the whole composing a dense tangle 

 through which passage must be cut with a knife. (Sec Plate 1\', 

 lower figure.) 



Almaguer, 20 miles west of the " Valle de las Papas"; the village 

 of that name is at an altitude of about 7,500 feet, but the craneflies 

 so labelled were taken in the vicinity of a camp on the mountain ridge 

 west of the village, at an altitude of 10,500 feet. This is in the 

 '■ moss " forest and most of the insects were obtained along a trail 

 cut through the forest ; in the open places Sphagnum grows commonly 

 and blue-berries with non-edible woody fruit occur in abundance along 

 the trail wherever trees have been removed. 



Popayan, 40 miles N.N.E. of Alniaguer, at an altitude of 6,500 

 feet; this is below the level of the "cloud" forest and is largely open 

 country with savannah conditions, open hills with little woods except 

 along the rivers.
