Potato Weevils from South America 
35i 
in shipments received May 24, 1913, from Mr. Wight, who collected the 
material at Cuzco, Temuco, and Arequipa, Peru; Oruro, Bolivia, and 
Ancud or San Carlos and Castro Islands, Chile. In many instances the 
injury occasioned by these weevils was quite noticeable. A few of the 
tubers which superficially appeared to be sound were found, on being 
opened, to be infested with one and sometimes two larvae or adults. Mr. 
Sasscer succeeded in keeping two adults alive from May 24 to September 
6, during which period they fed but little and then only on foliage of 
potato. The injury of this species consists of tunnels throughout the 
potato, as shown in Plate XXXIX, and the work of the two other 
weevils is very similar.
