SATYRIXAE: SATYRODES EURYDICE. 197 



lowii (Allen), and it is reported from eentral Iowa (Osiborn), northern 

 Illinois (Worthington, Edwards), Indiana (Edwards) and Wisconsin 

 " not rare " (Iloy). It has been captured at Mingan Island off southern 

 Labrador (C()uper),at Quebec (Bowles), Montreal, " abundant" (Caul- 

 field, Lyiuiin) and Ottawa, "abundant" (Billings, Fletcher). It has 

 even been taken at Great Slave Lake, and at Rupert's Fort on the east side of 

 Hudson Bav, but has not been reported from Labrador. To the east 

 it is reported from Colchester Co., Xova Scotia, by Jones. 



In New England it is not a very rare insect, especially in the northern 

 and elevated parts. It has been taken to the eastward at Orono (Fernald) 

 and Mt. Desert Island, Me. (Scudder). There is no notice of its capture 

 south of Massachusetts, where it has been taken in Williamstown (Scud- 

 der), at ^'arious points in the Connecticut Valley (Dimmock, Scudder, 

 Sprague), and by many collectors about Boston where, though not 

 a))undant, it is by no means rare ; farther nortli, in the latitude of the 

 White Mountains and as far as Compton, Canada (Gosse) , as Avell as in the 

 Adirondacks of New York (Hill), it will be found extremely abundant by 

 those Avho look for it in its proper haunts. 



Haunts. These are elevated, moist meadows, particularly those lying 

 on hillsides, and it is so restricted to them that one may sometimes find it 

 in a spot but a few acres in extent and search in vain beyond. The only 

 notice of its capture in any other place is of a single specimen by Mr. 

 Allen, from a shady ravine in Iowa. It would probably be found in con- 

 siderable abundance where it is now considered rare, were it sought for in 

 the proper stations. 



Larval habits. The food plants of the caterpillar are the coarser grasses. 

 Mr. Edwards had poor success in raising them on lawn grass ; with me 

 they fed on it readily enough. Mr. Fletcher found them feeding by day 

 on Scirpus eriophorum and Carex bromoides. To escape from the egg, 

 the young larvae bite a channel around the summit, forming a lid about 7 

 mm. in diameter ; but instead of then leaving the egg they frequently eat a 

 second hole on one side and there make their escape ; once out, they 

 sometimes devour the whole shell, leaving nothing but the attached base. 

 During their earlier stages, the caterpillars are exceedingly quiet, remain- 

 ing on a single blade of grass near the tip, from the sides of which they 

 eat long, irregular patches, nearly or quite to the midrib, with very slow 

 movements ; they continue thus until several days after their second moult, 

 Avhen they not only begin to eat more rapidly and abundantly, but wander 

 restlessly about from blade to blade ; they eat mostly or only by day. 

 When moulting, the horns of the new head are directed forward, lying 

 flat upon the front beneath the old skin. When active, these horns are in- 

 clined forward, their hinder edge forming an angle of about 35° witji the 

 perpendicular; when at rest, the head is bent beneath the body so that the 

 hinder edge of the horns lies on a line with the dorsal surface of the body ;
