10 (?.— This is a much larger species than E. cambricaria, hut with very 

 similar markings. It may always be distinguished l)y the; simple mah^ antennte. 

 Body and wings pale ash-gray. Fore wings with eight well-defined sinuous 

 or scalloped blackish lines, most distinct on the costa and veins; the basal 

 line is heavy, and bent rectangularly between the subcostal and median veins;, 

 the next line, rather remote from the basal, curves inward on the subcostal 

 vein, and outward on the median space ; the two lines beyond are approxi- 

 mate, but less .sinuous; the fourtli line from the base of the wing is broad, 

 ditl'use, twice as broad on the costa as the three others; beyond this line is a 

 clear median space, in the middle of which is the distinct discal dot; beyond 

 are four more or less distinct lines, of which the outer (or submarginal) is 

 mo.st distinct and regularly scalloped ; a marginal row of twin black dots; 

 friiiifc whitish. Hind wings with traces of" four .scalloped lines, the marginal 

 one the heaviest; marginal spots and fringe as in the fore wings; beneath, 

 the lines on the hind wings are much as aljove ; but those on the fore wings 

 are obsolete, represented by four costal spots on the outer half of the wing. 



Length of body, <?, 0.45; of fore wing, S, 0.75; expanse of wings, 1.60 

 inches.
