In his investigation of the transmission of the disease called 
“ verruga peruana ” and the search for the insect transmitter, 
Prof. C. H. T. Townsend collected blood-sucking Diptera in the 
verruga zone. Among those submitted to the writer for deter¬ 
mination were four species of Simidium, and of these three 
proved to be new to science. Another species still undescribed 
was collected by Professor Townsend in 1911 on the eastern 
slopes of the Andes and still another was collected in 1911 by 
the YEle Peruvian ICxpedition. Five species have been pre¬ 
viously reported from Peru and this brings the number of 
species known from this country up to ten. These may be 
separated as follows: 
:\Iesonotuin black or grey, without contrasting ccdors. 6
