"2 c? . — This species heloiiifs to ;i distiiicl s(K-li()ii of llie ifeiiiis, inid is 

 intoriiiediiilo between ('. Inuihirid and (,'. niiiJ>ioti(ui(i ; the antenna', being 

 broadly pectinated, ])luni()se to just before the tip, tiie branches Ijeing rather 

 longer than in C. umbrosaria, while the wings arc shaped somewhat as in 

 C. huinarla. The lines are straight, not waved, and bent, and in this respect 

 it reseinl)les Hemerophila. The hind wings are distinctly notched on tlu; 

 independent vein. Front dark brown, with a white line in front. Vertex 

 whitish. Body and wings dull ash. Fore wings with brownish scales at 

 the base of the wing and beyond tin; outer line; thre(; black lines, the inner 

 nuich curved, ol)liquely curved on the costa, and from tlu! median vein 

 directed obliquely and ending nearer the l)ase of the wing than nsual ; middle 

 of tlie wing paler than elsewhere; a faint discal dot; middle line sinuate, 

 approaching the outer line just below the median vein ; outer line very 

 distinct, bent at right angles below the last (sixth) subcostal vein, and thence 

 to the inner edge very oblique and not curved ; beyond, the wing is reddish- 

 brown, inclosing a zigzag, white, snbmarginal line; a marginal row of black 

 dots. Fringe concolorous with both wings. Hind wings like the fore wings, 

 with two black lines, the inner diffuse, straight, not reaching the costa, tin; 

 outer more distinct, curved round opposite the distinct discal dot to the 

 costa, but directed straight to the hinder edge; beyond, reddish-brown, and 

 marked as in the fore wing. Abdomen with a faint l)lack line at the Inise, 

 and the hind edge of the segments touched with black. Beneath, botii 

 wings uniformly ash, with a faint ochreous tinge on the veins and the costa, but 

 no lines, apd the discal dots distinct (or very faint and diffuse). The marginal 

 row of venules sometimes distinct. Fore legs dark within, paler externally. 

 Hind legs pale. 



Length of body, c? , 53 ; of fore wing, i , 0.53 ; expanse of wings, 1.U8 

 inches.

This interesting species may be known l)y the very plumose antennae, 

 the straight outer line and reddish-brown margin of the wings, the simple 

 discal dots, and by the notch, or sinus, in the hind wings.
