a round, small,. but distinct discal dot; an indistinct submarginal band; five 

 dark bands on the inner edge, which do not pass beyond the median vein. 

 Margin of wings uniformly dusky, without any light or dark scales. On 

 second ring of abdomen, a broad black band, interrupted by a pale, mesial, 

 white, narrow band, which extends along six rings, with a mesial black dot 

 on each ring. Sides of abdomen with brownish scales ; extreme tip pale 

 luteous. Margin of both wings black; fringe as in fore wings; beneath clear 

 cinereous, with no brown scales ; the broad costal dark bands inclosing two 

 much smaller bands; a short line half-way between discal dot and outer edge 

 of wing. Margin of both wings dusky, containing a white hair-line ; fringe paler 

 than margin of wing. Hind wings with five dusky lines, two within the discal 

 dot (sometimes wanting); the third, including the dot, very narrow; the two 

 outer ones broader, especially the submarginal one, which reaches to the edge. 



Length of body, 0.20 ; length of fore wing, 0.30 ; expanse of wings, 0.85 

 inch.

Differs from E. Strattonata, to which it is rather closely allied, by the 

 wings being more cinereous, and beneath with no brown scales at all; by the 

 geminate white V-shaped spot on the inner angle, and the five lines on the 

 under side of the hind wings, which only appear on the inner edge above; by 

 the interrupted black band on the second abdominal ring, and the white line 

 on six rings, each ring clouded by a black dot; and by the very pale luteous, 

 straight, converging hairs of the extremity. 



This is our most common species, and may be distinguished by the 

 pointed fore wings, with the numerous transverse lines angulated sharply out- 

 ward, the extra-discal line forming a sharp angle opposite the discal dot, and 

 notched inward on the subcostal vein ;' by the distinct submarginal wavy 

 white line ending in a large white twin spot at the inner angle; by the fine 

 dark lines on the hind wings ; and by the heavy black costal spots and mar- 

 ginal lines on the under side.
