421 



pale fringes. Beneath thickly powdered with blackish, with a 

 slight ruddy stain ; hind wings with dot and line. 



Expanse 40 mm. 



From the White Mountains, New Hampshire, collected by Mr. 

 Geo. Dimmock, for whom I name the species. 



Cirrhophanus triangulifer, Grote, Can. Ent. 4, 187. 



% . Antennre with thickened scape, simple, scaled above, 

 ciliate beneath. Eyes naked. Thorax tufted; wings rounded. 

 Front roughened, tuberculate; palpi slender, short. Legs un- 

 armed. Rich, rather pale, silky yellow, with deep yellow linear 

 shadings. Fore wings with the usual markings wanting. All 

 the markings deep ochre-yellow, consisting of curved or straight 

 shadings on the veins and interspaces. The t. p. line seems near 

 the margin, geminate, shaded, even, forming a rounded sweep from 

 opposite the eell to below vein 2, where it is indented ; it here 

 appears to be disconnected, running back on the vein ; below this 



two curved ochre lines on each side 

 of vein 1 seem to meet on the t. p. 

 line. Thus two triangulate spaces 

 are formed on the primary. Sub- 

 terminal and terminal lines indi- 

 cated. Fringes and hind wings 

 shiny yellow. Beneath yellow with- 

 out markings. 



Expanse 40 mm. Kansas, Prof. 

 Snow. 

 By the kindness of Professor C. Y. Riley I am enabled to pre- 

 sent the annexed beautiful wood-cut, illustrating the female type 

 of this species and showing the neuration. The student is re- 

 ferred to the original paper for my remarks on the structural 

 affinities of the moth, which seem to me to lie with Gortyna. 



Lygranthoecia limbalis, n. s. 



?. Allied to arcifera. Fore wings deep shining blackish- 

 brown; thorax more reddish. A 11 the lines obliterate; the an- 

 nulets of the reniform can be made out. On the middle of the 

 wing there is a whitish patch on internal margin, and one above 

 it, smaller, on costa. Hind wings black, immaculate, with pale 

 fringes. Beneath black, with the terminal spaces reddish. 

 Abdomen black, with the terminal segment yellowish.
