Many other species of Tabanidæ, popularly called "Breeze Flies," are plentiful in this country.
Family 18, Leptidæ.—These insects are mostly predatory, though many small species are parasitic on animals and other insects. The larva of Vermilio degeerii lives in sand, and feeds on such insects as fall in its way. Those of the genus Leptis are parasitic on cockchafers and other large beetles.

Family 19, Asilidæ.—The Asilidæ or Hawk Flies are a family of considerable extent, and include many very large and conspicuous insects. They feed on other insects, and are very courageous, sometimes attacking even dragon flies. One of the most common species is Asilus crabroniformis, which is common in the south of England.
Family 20, Midaidæ.—These are large insects resembling the Asilidæ in their habits, and are nearly all tropical. A few species, however, inhabit the south of Europe.
Midas giganteus is found in Brazil and adjacent countries in tropical America. It measures about one inch and a half in length.
