 in tlir fore wings, Beneath, body and wings ocher-yellow, especially in the 

 middle of the wings. Both wings marked alike with a basal, diffuse, broad, 



brown line, and an outer, much curved, brown hair-line. An outer row of 

 dark patches forming a faint broken line. An apical, oblique, whitish patch. 

 Beyond t lie outer hair-line, hot h wings darker. Hind edge of lore wings with 

 darker spots and patches than elsewhere. The female is of nearly the same 

 form as the male, hut with much larger deeper notches. < >n the under side, 

 the costa and hind edge are gray, with blackish scales. Discal dot distinct 

 above, larger beneath. Inner band wanting. Beyond the outer line, the 

 wing is fawn-brown, more as above, and the entire under surface is more 

 thickly speckled than in the male. On the upper side of the lore wings are 

 three dark patches, one at the inner angle and two near the apex.

This species is larger and differently marked from E. armataria, and is not 

 so acutely dentate on the outer edge of either pair of wings, which are uniformly 

 clear fawn-brown, witli darker lines, but not the broad heavy bands of arma- 

 taria. The two male and female specimens from Vancouver's Island and one 

 male from California follow the usual law of variation of intercontinental 

 species, 'and are much larger than eastern examples; but the markings are 

 essentially the same, the dark patches on the outer margin of the fore wings 

 being well marked. 



Length of fore wing of a Massachusetts example, 0.70; of a Van- 

 couver's Island specimen, 0.85 inch. 



The Nebraska and Kansas specimens do not differ in size from eastern 

 ones. 



Larva. — The caterpillar has been found by Mr. W. Saunders feeding on 

 the oak. Unfortunately, it was not described. It went into the chrysalis 

 state on the 4th of July, and on the 17th, or thirteen days after, emerged.
