ward turning scallop at the tip of the anal angle 

 of the hind wing. 



The Hoary Elfin 

 Incisalia irns (In-ci-sa'li-a i'rus) 

 Plate XXXV, Fig. 4, 5, 6 

 See the preceding description. 



Caterpillar. — Slug-shaped; one-half an inch long ; head 

 very small ; body downy, greenish above and reddish brown 

 on the sides. 



Food-plant. — Wild plum. 



The gray which gives this elfin its name is only 

 seen on the outer half of the lower side of the 

 hind wings, and often it is more lilac than gray ; 

 except for this it is as brown as the other elfins. 

 It is the laziest of all the hair-streaks and loves to 

 loaf around shrubs in open places, and even 

 haunts the roadsides. The caterpillar is a little 

 rascal that burrows in and devours the fruit of the 

 wild plum. 



The species is distributed from the southern 

 part of New England to Georgia and westward 

 to Missouri.
