PIEIilD.F.. 



The habits of the Perfect Insects must be very varied, but we know little of those of the exotic species. 



The two most common European species are but too well known as the pests of our kitchen-gardens, and, to a less 

 extent, of our parterres. Pieris Daplidice in Europe, and Pieris Protodice in America, are less frequent in gardens : 

 they have a quicker flight : and the latter, as far as I have observed, is never seen playing in groups, and ascending into 

 the air, as our Pieris Brassiere and Pieris Rapae are often seen to do. Pieris Callidice frequents the summits of the 

 Alps and Pyrenees, and is found also on the Rocky Mountains of America. It ascends to the limits of perpetual snow. 



Pieris Demophile, Pieris Margarita, and Pieris Monuste are stated by Lacordaire, in his remarks on the entomology 

 of Guiana, to frequent the summits of the trees during the day, and to descend to rest in the brushwood at sunset. 

 In Florida I have never observed this habit in Pieris Monuste ; on the contrary, I have generally found it flying low, 

 in old cotton fields, or the openings in the oak woods, and alighting frequently on flowers. 



The Geographical Range of the species is very great, Several species appear to extend over nearly all Europe, N. 

 Africa, and Asia as far south as Cashmere, and even the Neilgherries. One or two species are common to Tropical 

 Asia and Africa. The Australian species all appear to be peculiar to that continent. Pieris Callidice I believe to be 

 the only species as yet known to be common to the Old and Xew Worlds. 



In the Arrangement of the Species I have endeavoured to place them in natural groups, founded chiefly on the 

 neuration of the wings; but, as there are many species only known to me by descriptions or figures, I leave these 

 with hesitation in those groups to which I imagine them to belong. It is possible that in some cases the sexes may 

 vet be placed in separate sections, as has been the ease hitherto with several species.
