Professor Forbes writes of the injuries to these Bill-Bugs as follows:* As larvae these species live and feed, as far as known, in the roots of grass-like plants, less commonly boring also the lower part of the stem. Grasses with bulbous roots, like timothy and the club rush, are probably their more normal breeding plants. In timothy meadows the hollowing out of the root bulb frequently kills the plant—if not outright, then the •Sixteenth Rept. Ills. State Entoniolo«isit, p.
