The Genus Neophasia Belir. 



The late Baron Terloot de PopeJaire, many years ago, 

 while on a journey through the pine forest region of the 

 Sierra Madre, from Dnrango to the Pacific Coast, collected 

 a peculiar butterfly, and, having no better means of pre- 

 serving it on a hurried trip through a region infested by 

 Indians, pressed it in his pocket-book. 



This specimen, considerably shattered, but showing all 

 its essential characteristics, came into my hands. I saw it 

 to be a near relation of Pieris Blenapia Felder, and a close 

 inspection of the nervation of its wings revealed the fact 

 that the insect could not be comprised in the genus Pieris. 

 A careful study of Menapia, which it so much resembled, 

 made it evident that both species were congeneric, belong- 

 ing to a new genus having characteristics of Leptalis and 

 Euterpe, and even of the Asiatic genus Pontia, and the 

 European Leucophasia. On this species, Menapia, and the 

 new one which I called after its discoverer Terlootii, by 

 misprint Terlooil, was founded the genus Neophasia. 



Since that time various webs of very peculiar structure 

 have reached me from different parts of Northern Mexico, 

 with the statement that they were the work of caterpillars 

 living in them through the rainy season, and producing a 

 butterfly, not a moth, early in spring. These nests were 

 only found at an elevation beyond permanent human habi-
