THE CANADIAN ENTOMOLOGIST. 237 



median 3-branched ; vein 4 wanting ; 5 joined to median at right 

 angles from a true vein, the commencement of the cross-vein ; 6 and 7 

 together from a point beyond the closure of the cell ; 8 out of 7 near the 

 base. ^ antennge simple, scaled, ciliate beneath. 



Argyrophyes cilicoides is chalk white ; the basal half of primaries white ; 

 on the outer half of the wing the terminal portion of the median space is 

 shaded with smoky, enclosing a raised blotch of black metallic scales at 

 the extremity of cell. A waved smoky subterminal line dividing the white 

 terminal field and very near the margin. Beneath the primaries are 

 smoky except along internal margin at base. Hind wings white with a 

 smoky shading within the fringes ; beneath with a faint dot. Body white. 

 Expanse 16 m. m. New Jersey. I find that my two specimens were 

 males. 



"\"ery near to cilicoides is Nola nigrofasciata of Zeller, Taf. 2, fig. i, but 

 it is impossible that it is the same. The color of the band is " brown " and 

 it occupies the middle of the wing, and is well defined in Zeller's figure. 

 In cilicoides there is no middle band or median space, but the smoky 

 shading is limited to the outer part of the median space without the usual 

 place for the median shade line. The narrow exterior line is evenly 

 arcuate to submedian fold. The white terminal fields are narrower than 

 in nigrofasciata. 



But I have a species received from Mr. Goodell, Amherst, Mass., the 

 specimen numbered 602, which closely agrees with Zeller's figure and 

 description except that it is a little larger (19 mil.). The median band is 

 not quite separated at its submedian constriction, but this is an ordinary 

 varietal character. Else it agrees perfectly. There is the dot en median 

 vein at base and costal shade (entirely wanting in cilicoides), and the faint 

 mark before the inception of the subterminal line. No doubt can remain 

 on my mind that I have Zeller's species before me. Now this species has 

 been evidently re-described by Mr. Morrison, Boston Proc, 154, 1874, as 

 Eustrotia obaurata ! But the palpi are the palpi of Nola and not of 

 Eustrotia. They are rather the palpi of Argyrophyes, being longer than 

 in Nola and with a more pronounced upward curve. The vestiture is 

 wholly scaley and not like that of Eustrotia. And the ocelli cT.e wanting. 

 All doubt fades when we come to examine the neuration. // agrees pre- 

 cisely until Argyrophyes, and just in those points, accordingly, where 

 cilicoides differs from cefitofialis. The median vein of secondaries is 

 3-branched, vein 4 wanting, vein 5 joined at right angles by a true vein
