The Pieridae are distributed almost, if not quite, as widely over 
the globe as the last family, and we shall group the genera in 
the same manner. Pieris (130 sp.) is cosmopolitan; Terias 
and Callidryas are found in all the four tropical regions, and as 
far north as Pennsylvania in the Nearctic region ; Pontia , 
Tachyris , Eronia, and Thestias are common to the Ethiopian, 
Oriental, and Australian regions, the last-named, however, 
only extending as far as Timor; Colias is pre-eminently 
Paloe arctic and Nearctic, with a few Ethiopian species, one 
Indian, two in Chili, and one in the Sandwich Islands ; Antho- 
charis is wholly Palsearctic and Nearctic ; Midea has two species 
Nearctic, and one in Japan ; Gonepteryx is Pahearctic and Neo- 
tropical, extending into Texas ; Idmais and Callosum are 
Ethiopian and Oriental; Thyca and Ipihias are Oriental and 
Australian ; Meganostoma is Kearctic and Neotropical ; Na- 
thalis and Kricogonia are Neotropical, ranging into Florida, 
Texas, and Colorado. 
The peculiar genera are pretty equally distributed. The 
Neotropical region has ten, two being confined to Chili; Euterpe 
and Leptalis are the most remarkable, the latter containing a 
number of forms mimicking the Heliconidse and Danakke. The 
Oriental region has two, Prioneris and Pereas ; the Australian 
one, Elodina ; the Ethiopian two, Teracolus and Pseudopontia ; 
the Palsearctic two, Leucophasia and Zegris ; the Nearctic one, 
Neophasia.
