lated, tlie curves directed iiiwtirdly, and the line preceded by a more or 

 less wellnuirked black shade, which is always more distiuct on the 

 costa. A series of black terminal dots. Orbicular wanting. Eeniforni 

 never well marked, blackish, indefinite, sometimes annular, never 

 entirely Avanting. Secondaries more thinly scaled and somewhat paler, 

 crossed by an extra mediau dusky line, which becomes obsolete toward 

 the costa, and by a pale extra meilian line, which is emphasized by a 

 blackish preceding shade, most marked toward hind angle. Beneath 

 whitish, powdery, both wings crossed by a fairly evident, sometimes 

 prominent, extra median and a more faint, usually punctiform, outer 

 dark line. A discal spot is also obvious on all wings. 



Expanse of wings, 1*0 to I'L' mm. = 0.80 to 0.88 inch. 



Habitat. — Nova Scotia to North Carolina, to Central States; New 

 York and New Hampshirean June. 



This species is much more rare than Z. UturaUs and seems inclined to 

 be more variable. The type of Z. gt/psalis which 1 examined in the 

 British Museum is a partially suffused specimen in which the base of 

 the primaries is shaded with ochery and the subterminal and terminal 

 spaces sprinkled with dark brown. It is not entitled to varietal rank, 

 because the difference is rather in the nature of an aberration. The 

 male antenna' have the lateral bristles well developed and the thick- 

 ening at the basal third well marked, chietiy by dense scales on the 

 outer side. Two joints are furnished with stout, i>ractically identical 

 spurs, inwardly. The female antenna:' are feebly ciliated only. The 

 fore legs of the male are prominently tufted. The coxa has only a few 

 scattering hairs, and is not grooved; the femur is grooved on thenpi)er 

 side, has a tnft of scales at base and a pencil of long yellow hair 

 attached at the tip. The tibial process is very broad and large, but 

 covers a comparatively small tuft of hair, the tufting of the femur 

 being in this case the most imi)ortant. 



Zanclognatha niinoralis, new sppcies. 



Pale ashen gray, with fuscous powderings. Head and thorax con- 

 colorous. Primaries with the median space almost white, the basal 

 space and all beyond the transverse posterior line with a fuscous 

 washing. Basal line rather broad, diffuse, extending below the median 

 vein. Transverse anterior line broad, diffuse, fuscous, somewhat 

 dilated on tlie costa, in course with an even outcurve, and outciirved 

 also between the veins. Transverse i)osterior line single, well defined, 

 broad, scarcely if at all dilated on the costa, with small outward teeth 

 on the veins; broadly outcnrved over the cell and with a feeble 

 incurve below. Subterminal line whitish, rather obscure, even, nearly 

 straight in course, i)receded by a fuscous shading. A series of lunate 

 dusky terminal spots. Through the outer part of the median space 

 is a vague, fuscous median shade, crossing the reniform. Orbicular 

 Avanting. Keniform distinct, rather small, oval, with a fuscous shading.
