220 THE CANADIAN ENTOMOLOGIST. 



Two males and two females. Mr. Dod was good enough to send me 

 these specimens because they seemed to him — justly enough, as it proved — 

 different from gussafa, which flies with it. The chief superficial difference 

 is that the new species lacks all the black marks of the older form. There 

 is no basal black streak, no black margined claviform and no black line 

 to the t. p. line. The antenn?e of the male are brush-like — /. e., the joints 

 are a little produced laterally and furnished with tufts of bristly hair. 



Ha den a cerivafia, n. sp. 



Head, thorax and abdomen a very pale dull gray, more or less tinged 

 with red, especially in the female. Patagite with a blackish shade at base of 

 primaries, else head and thorax immaculate. Primaries with all the 

 normal maculation fairly well written, but not contrasting ; much better 

 marked in the female. There is a distinct, irregularly thickened black 

 basal streak, extending about half way to the t. a. line, and this is the 

 most contrasting bit of maculation in the wing. Basal half line geminate 

 on costa, outer portion lost, inner brown or blackish, a little irregular. T. 

 a. line geminate, outer portion blackish, inner tending to become lost, as 

 a whole rather evenly outcurved, only a little drawn in on the veins. 

 T. p. line geminate, outer portion even, smoky, tending to become lost 

 in the outcurve over cell, inner portion blackish, tending to become 

 lunulate, drawn in below cell, close to or actually touching inferior angle 

 of the reniform. S. t. line irregular, concolorous, marked on costa by a 

 darker preceding patch which fills the s. t. space, thence by a narrow, 

 broken, brownish preceding shade, the terminal space sometimes darker 

 in whole or in part. A series of black, distinct, terminal interspaceal 

 lunules. Median shade line smoky, oblique between the ordinary spots, 

 thence close to and parallel with the t. p. line, never prominent, usually 

 obvious, rarely almost obsolete. Claviform very short, blackish or brown 

 edged, tending to become obsolete. Orbicular large, a little paler, 

 narrowly edged with black scales, tending to become incomplete above. 

 Reniform rather large, kidney-shaped, tending to become a little con- 

 stricted in the centre, partly black edged, incompletely pale annulate, 

 inferiorly dusky filled. Secondaries smoky, in the female with a somewhat 

 paler, more reddish tinge. Beneath powdery, disc of primaries a little 

 darker, all wings with more or less obvious darker extra median lines 

 and obvious discal spots.
