120 Messrs. F. Du Cane Godman and Osbert Salvin's 



open savanna, with but few trees and barren Mil-sides, the 

 forest, of small extent, being restricted to the neighbour- 

 hood of the mountain called Chinchicua, which reaches an 

 elevation of 11,000 feet, a little to the southward of the 

 higher peaks of the Nevada itself. To this scarcity of 

 forest the poverty of the fauna must in a measure doubtless 

 be attributed ; but something must also be set down to the 

 difficulties lying in the way of a collector making any length 

 of residence in these high regions. We still hope to see 

 considerable additions to the number of species of butter- 

 flies of this district, as in those that have already reached 

 us we trace the elements of a much richer fauna. 



Besides working in the Sierra Nevada, Mr. Simons made 

 an expedition to the southward, and spent some time at a 

 place called Manaure, situated on the northern spur of the 

 Andes, at an elevation of 2,700 feet above the sea. Here 

 he found a much richer fauna, as will be seen from the sub- 

 joined list. But the peculiar species of the Sierra Nevada 

 do not appear to extend to this district, the butterfly fauna 

 being made up of a mixture of Colombian and Venezuelan 

 forms of considerable range ; with these are intermingled 

 a few hitherto only known from Central America, and 

 others we now describe for the first time. 



The localities mentioned in the following list are situated 

 as follows : — 



Manaure. 

 Elevation, 2,700 feet. A cofiee plantation south-east of 

 Valle Dupar, on the western slope of the northern spur of 

 the Andes. 



CsmcHicuA AND Chinchicua Valley. 

 Not given in Mr. Simons' s map, but doubtless situated 

 on the slopes of the Chinchicua mountain, which attains an 

 elevation of 11,000 feet, and is situated on the south side 

 of the Nevada. The only forests in the Nevada are situated 

 here. 



Atanquez. 

 Elevation, 2,800 feet. On the south-eastern slope of the 

 Nevada, six hours' journey from Valle Dupar. 



San Sebastian. 

 Elevation, 6,700 feet. On the south-western slope of the 

 Nevada.
