A REVISION OF THE DEI/rOID MOTHM SMITH. 41 



costa well before the ;i]>e\ to the iiuiei' miirjiiii well within the aii;il 

 angle. A blaekish, teiniiiial, (l()tt<'(l line on the veins. Orbicular want- 

 ing; renitbrin small, a brown line or liiniile. Secondaries soniewliat 

 paler than i^iimnries, with a rather \a.uiie, often obsolete discal liinule, 

 a somewhat indistinct extra median dark line, whicli is snbangnlate 

 toward the inner margin, a more distinct subterminal l)i-own, tollowed 

 by a yellowish line, and a narrow, dark terminal line. l>ene;ith ])al<'r, 

 l)owdei'y, all wings with a blackish discal spot, a rather well-marked 

 extra median line, and a variably distinct subterminal line whi(;h is 

 olten followed by a pale shade line. 



Expanse of wings, 25 to 28 mm. 1 to l.li! inches. 



Habitat. — Nova Scotia to Virginia; Central States; New Mexico; 

 New York; Illinois and District of Columbia, July and August. 



The type of Mr, Walker's species is the same as the Z. cnirKlisoi the 

 Grote collection, which T believe to be correctly determined. The Z. 

 cntrolis of Walker is the Z. I(cri(/(ifa of Mr. Grote. 



This species is quite common, and is very little subject to vjiriiition. 

 In its markings it is very like Z. pcdipihdis except as to the subterminal 

 line, and it has the same tendency to form an angulation in the trans- 

 verse posterior line over the cell. Small specimens which are a little 

 rubbed may be easily con fused with Z. ohscuHpcnnis, \yh\r\\ ditlcis mainly 

 in the denticulated transverse i)osterior line. 



The antenna? of the male are after the usual type; but the bend at 

 basal third is much more prominent, and beyond it the joints are more 

 slender than toward the base. Two joints are furnished with corneous 

 processes which are very stout and pointed, and when at rest join at 

 the tip so closely as to ai)pear like a single heavy process at that point. 



The fore legs of the male are well furnished with tuftings. The coxa 

 is grooved and furnished with an imperfect pencil of slender scales 

 attached at and n<'ar the base. The trochanter is rather more than 

 one fourth the length of the femur. The femur is grooved on the upper 

 side, furnished with a tuft of elongated black scales at the l)ase, andat 

 the tip with a pencil of li>ng, flattened, yellow hair, which nniy be spread 

 fanlike. The tibial pro(;ess is very large and covers a dense mass of 

 black>«h scales which are elongated without forinini; a. distinct brush or 

 pencil, and are not capable of fanlike expansion.

Ground color a pur})lish smoky brown, rarely varying to a reddish 

 shade. Primaries with the maculation obscure. Basal line wanting. 

 Transverse anterior line fairly distin(;t, bent over the costa and nearly 

 straight below this point. Transverse ])osterior line slender, thread- 

 like, obscure, often partly obsolete, more or less ol)\ iously but iilways
