FAMILY BRUSH-FOOTED BUTTERFLIES. l09 



small black ocelli distant from the margin. Under surface slaty 

 brown, paler beyond a strongly-waved median brown line, the 

 ocelli repeated, but larger and more complex. Expanse 2 inches 

 or more. 



Caterpillar. — Head green, the coronal tubercles very high, 

 conical, red with brown stripes. Body naked, briefly pilose, 

 green, longitudinally striped with darker or lighter green ; a dis- 

 tinctly constricted neck and long caudal fork. Length 1^ inches. 



Chrysalis. — Green with buff longitudinal stripes ; head acut- 

 angulate as seen from sides ; abdomen with no longitudinal 

 ridges, the part beyond the wings as long as they are. Length 

 I inch. 



The smooth, snbglobular, pale green eggs, Laid singly, 

 hatch in from seven to nine days. The caterpillars, on 

 leaving them, sometimes devour a part or the whole of the 

 egg-shell and feed on grasses and sedges, having been found 

 on Scirpus and Carex ; they feed and mature very slowly, 

 are at first exceedingly sluggish and when not feeding re- 

 main on the blade of grass serving as food ; but later in 

 life they move about restlessly though slowly and eat with 

 more relish, feeding apparently only by day and mostly in 

 the early morning; they hibernate in the larval condition, 

 nearly grown. The chrysalis hangs for about nine days. 

 The butterfly is found from Iowa to the Atlantic, but does 

 not appear to extend further south than central Ohio and 

 Pennsylvania,* though reaching northward to Hudson 

 Bay. It is found in elevated, moist meadows, and is 

 single-brooded, flying in July and the first half of August.
