Fifty families are represented in the intertropical portions of Asia and 

 Africa. Of these nearly thirty do not range much beyond the Northern 

 Tropic, of which about twenty-three are limited to this region. Of the 

 thirty-two families occurring in the north-temperate zone (of which only 

 six or seven are exclusively Europa30-Asiatic), nearly, one-half range 

 over most of the indo- African tropics. The following is a list of the 

 families represented in the Old World tropics, exclusive of those limited 

 to Madagascar and the Australian Realm.
