 (lark ])atches forming a faint broken line. An apical, oblicpic, whiti.sh patch. 

 Beyond the outer hair-line, bolli wings darker. Hind edge of fore wings with 

 darker s])ots and patches than elsewhere. Tlie fismale is of nearly the same

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

 above, larger beneath. Inner band wanting. Beyond 1he outer line, the 

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

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

 so acutely dentate on the outer edge of either pair of wings, whicli are uniforndy 

 clear fliwn-l)rown, with darker lines, but not the broad heavy bands of anna- 

 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 nnirked. 



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

 couver's Island specimen, 0.86 inch. 



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

 ones. 



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

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

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