By its persistence it often even drives out other grasses and clovers from the meadows and pastures. The fact that bluegrass is one of the richest of grasses in digestible protein helps explain the fondness for it shown by stock. Differing from

Great difficulties attend their study on account of several points in their economy, such as, that the sexes are different, and frequently not found together; also that there may be two generations of a species in one year, these being more or less different from one another. Another considerable difficulty arises from the fact that these bees are subject to the attacks of the parasite Stylops, by which their form is more or less altered.
