"t right angles to costal portion of line. Externally this line is obscurely bor- 

 dered by a narrow creamy yellow line which on the margin forms the first of the 

 white costal spots. Intradiscal line not apparent. Median line vaguely indicated 

 on lower half of wing, forming two large outward scallops between cubitus and 

 anal veins, and another below this latter vein. Discal spot elongate, scarcely 

 discernible. Extradiscal line formed by the exterior border of the median area ; 

 begins on costa about one-third in from apex and extends outwardly, scalloped 

 between the veins to inner margin, being as a whole gently outcurved to Cu.z 

 then straight to inner margin. The acute angles on all the veins are marked 

 with a spot of pure white, and on the costa is a yellowish mark just outward of 

 the extradiscal line. A second extradiscal line is seen a little further out on the 

 wing running parallel with the first. All the veins from the first extradiscal 

 line to beyond the second are dotted black and creamy yellow. Subterminal 

 line creamy yellow, extends from costa to E4, and from there is apparent only 

 on the veins as spots. Terminal line almost black, slightly scalloped and marked 

 externally with a faint diffuse whitish dot in the angles of the individual scal- 

 lops and on their apices by a sharply defined white dot. Fringe concolorous with 

 ground color. Secondaries much paler brown than the forewings, very pale on 

 costo-basal area and becoming darker outwardly. Three transverse lines are 

 indicated on the outer third of the inner margin, from which shade lines may be 

 traced across the wing. Terminal line deep brown, scalloped, though less than 

 half as deeply as in packardafa and with white dots as on primaries. Fringe 

 concolorous with wing, the margin parallel with terminal line. Discal spot 

 brown, small, but distinct. Beneath : the forewings are evenly very pale brown 

 in the central portion, mixed brown and yellowish on the costal area and cream 

 colored on the inner area. The costal part of the extradiscal line and the dot- 

 ting of the veins is faintly reflected below. The hind wings are profusely pep- 

 pered with brown scales over a yellowish back ground ; the discal dot is small 

 and sharply defined, and the transverse lines are indicated by brown dashes on 

 the veins. 



Hab. — Soda Springs, Siskiyou Co., Cal., April 30 and May 25. 



Types : two males in the Hulst collection at Rutger's College. 



The species differs markedly from packardata by its larger size, 

 by the indefinite meculation and white spots on the veins, and, in 

 the hind wings, by the much less scalloped terminal line, which in 

 packardata is dentate. The third specimen in the Hulst collection, 

 also from Soda Springs (August 19th), is so badly rubbed as to be 

 almost unrecognizable. By the date of this latter specimen two 

 broods are indicated. 



Philereme iiigresc«»ns Hulst (Can. Ent., xxxii, 104, 1900), and Phile- 



reiue formosa Hulst (Trans. Amer. Ent. Soc, xxiii, 276, 1896). 



These two species must be transferred to the genus Mesoleuca. 

 This disposes of the genus Philereme in North America, muliiva- 

 gata having already been put into Mesoleuca by Taylor, while opti-
