The Moths brought home by the Ruwenzori Expedition were collected by the 

 Hon. Gerald Legge and Mr. A. F. R. WoUaston. A few species subsequently taken 

 at Entebbe and on the north-western shore of Lake Tanganyika by Mr. Wollaston 

 are also included in tlie present paper, and are distinguished by having " {A. F. B. 

 Wollaston) " placed after them. 



A large acetylene lamp which was taken out for collecting-purposes proved 

 almost a complete failure and attracted very few insects ; but the Moth-Fauna on 

 Ruwenzori seems to be remarkably poor, possibly owing to the almost continuous rains 

 to which the forests on the higher slopes are subject. The specimens were mostly 

 taken at two places : — 



(1) Mokia, S.E. Ruwenzori, 3500 ft., a dry plain covered with, short grass, 

 Euphorbia, and acacia-trees. Here the moths were of the usual mixture of East 

 and West African types which prevails throughout the greater part of the Uganda 

 Protectorate. 



(2) The Mubuku Valley, E. Ruwenzori, penetrates into the very heart of the range, 

 commencing between the snow-covered ridges. Up to about 8000 ft. its vegetation is 

 that of a tropical valley. The forest is then succeeded by bamboos, tree-heaths, giant 

 lobelias, and senecios, which extend up to about 14,000 ft. In the higher zones 

 possible traces of a Palsearctic fauna are represented by a few species of Noctuidee of 

 the subfamily Agrotitice, and Geometridse of the subfamily Larentiance. Episilia 

 rhoclopea was found at 12,600 ft., the highest point at which any moth was captured. 

 This species is more Palgearctic in appearance than any other in the collection.
