AMERICAN LEPIDOPTEKA. 17 



antennae of the male are closely ciliate, the edges of the joints a 

 little marked. Four males and females are under examination, 

 showing no evidence of notable variation. Nor have I seen any 

 appearance of such in other collections.

Ground color of head, thorax and primaries a dull, creamy gray, powdered 

 with smoky or black scales. Abdomen and secondaries smoky, the fringes pale, 

 contrasting. Head with a black line across the middle of the front. Collar with 

 a black line below the tip. Primaries with all the maculation present, fairly 

 well written, median lines geminate, all the lines well marked on the costa. 

 Basal half line rarely complete, but sometimes it meets a black basal streak, in- 

 closing a somewhat paler basal blotch. This basal black streak becomes some- 

 what diffuse inferiorly and sometimes extends almost to the t. a. line. T. a. line 

 broken, the defining lines very slender, inner often obsolete, included space con- 

 colorous, strongly dentate, the outward tooth in the submedian interspace reach- 

 ing nearly to the t. p. line and joined to it by a black shade spot. T. p. line 

 rather even, well outcurved over the cell and a little sharply drawn in below 

 vein 2, leaving a wide s. t. space. A series of geminate venular dots forms the 

 outer margin of the t. p. line. S. t. line pale, irregularly sinuate, preceded by 

 small blackish shadings opposite the cell and anal angle, and followed by larger 

 blotches at the same points. There is a broken, black terminal line. Median 

 shade usually evident and sometimes distinct, always darkening the space be- 

 tween the ordinary spots and usually marked from the lower margin of reniform 

 to the margin. Orbicular irregularly oval, oblique, outlined in black, sometimes 

 concolorous, sometimes smoky filled and then annulate with gray. Eeniform 

 upright, a little oblique, larger superiorly, black ringed, sometimes concolorous, 

 sometimes smoky filled and then annulate with pale. Secondaries smoky or 

 blackish, with a darker discal lunule, fringes whitish. Beneath, primaries with 

 disk blackish, terminal space gray, powdery ; secondaries gray, powdery, with 

 an extra median blackish line. All wings with a large black discal spot. 



Expands 35-40 mm. = 1.40-1.60 inches.

 ber ; Volga, South Dakota ; Decatur, Illinois, April 8th ; Cart-

Five males and one female are under examination. The macula- 

 tion is nowhere at all contrasting, and there is a tendency to a 

 blackish suffusion, which is strongly marked in the specimen from 

 Cartwright, Manitoba. The vcstiture is mixed, fine and flattened 

 hair, the anterior divided crest very distinct. The male anteniiae 

 are ciliated, joints a little marked.
