Specimens of Tylozygus are probably grass-feeders. T. bifidus (Say) is com- 
monly found on grasses in the U.S.A. 7. fasciatus (Walker) is reported by 
Martorell (in Caldwell and Martorell 1952a:14) in grassy meadows in Puerto 
Rico. Specimens of fasciatus from Colombia were collected on “legumes” and 
beans, in addition to grasses, and some specimens from Ecuador were collect- 
ed on sweet potatoes.
