Genus Atalopedes 



greatly enlarged, pale, and standing out boldly upon the dark 

 ground-color. The hind wings are pale brown on the inner mar- 

 gin. Expanse, $, i.ioinch; $, 1.25 inch. 



Early Stages.- — These have been elaborately described by 

 Scudder. The caterpillar feeds on grasses, making a tubular nest 

 for itself among the leaves. 



The insect ranges through southern Canada and New Eng- 

 land to Pennsylvania, and westward to Wisconsin. 



Genus ATALOPEDES, Scudder 



Butterfly. — Antennse short, less than half the length of the 

 costa; club short, stout, crooked just at the end; the palpi as in 

 the preceding genus. The cut shows the neuration. The only 

 mark of distinction between this genus and the 

 two genera that follow is found in the shape of 

 the discal stigma on the wing of the male, which 

 is described as follows by Dr. Scudder: " Discal 

 stigma in male consisting of, first, a longitu- 

 dinal streak at base of middle median interspace, 

 of shining black, recurved rods; second, of a 

 semilunar field of dead-black erect rods in the 

 lowest median interspace, overhung above by 

 long, curving scales; followed below by a short, 

 ration o'f°thegenus small striga of shining black scales, and outside 

 Atalopedes, en- by a large field of erect, loosely compacted 

 larged - scales." ' 



Egg. — Hemispherical, covered with a network of delicate raised 

 lines describing small polygons over the surface; minutely 

 punctate. 



Caterpillar. — Cylindrical, tapering backward and forward; 

 head large ; the neck less constricted than in the genus Eudamus 

 or in the genus Thanaos; dark in color. 



Chrysalis. — The chrysalis is slender, cylindrical, a little 

 humped upon the thorax, with the tongue-sheath free and pro- 

 jecting to the end of the fifth abdominal segment.
