34 TUK BUTTERFLIES OF Till: 



iiuumtT of flying, which is usually in a north or south 

 general direction, the writer has thought that they did 

 not breed here, but that the larvae were to be found 

 farther south ; and this has in a measure been confirmed 

 by never finding any larvse or eggs on their food-plants. 

 The food-plant of a species determines to some extent 

 the places of its resort. Cabbage and turnips being 

 largely the food -plants of Pieris Rapes, this species will 

 be found more about gardens and fields where these 

 plants are grown. The tame and prairie grasses furnish- 

 ing food for the different forms of Satyrus Alape, this 

 species will be found in meadows and prairies ; while the 

 Neonymphas and Debis Portlandia, feeding more on the 

 grasses growing in shady woods, may be sought in these 

 places. The Neonymphas fly low and with a jerking 

 motion, unless disturbed, but Debis has a different flight. 

 The male selects some tree, on whose trunk he may be 

 found, darting out upon every intruder, large or small, 

 to return again to his post ; the female being near by, 

 perched upon a blade of grass or a leaf. The Theclas 

 are to be found in some open wood or on bushes along 

 the border of a clearing. They rest upon the sunny side 

 of a bush on a leaf, frequently flitting out and back again 

 to the same or an adjoining leaf; and Feniseca Tarquinius 

 has a similar habit. The Lycanas are to be found more 

 about grasses and flowers, or hovering over some moist 

 place in the path or about some pool or small stream. 

 The different species of Pyrameis or Juuonia are often 

 to be found in a path or road, from which they will fly 

 up to alight a short distance ahead, flying past you after 

 this is repeated a few times. Limcnitis Disippus has a 

 similar habit, being found not far from some clump of
