THE CANADIAN ENTOMOLOGIST, 95 



The new Western species here described agrees with Pachypolia in 

 the pectinate antennae of the male, but is much less shaggy and more 

 slender. 



In diffusilis the male antennas are brush-like, perhaps sufficiently ser- 

 rate to be called pyramidal-toothed ( pyramidahaehnig). Of pallifcra I 

 have only the female type ; the abdomen is more noticeably tufted than 

 in the other species. I am doubtful about my determination of perqui- 

 ritata, and it is probable that I do not know any of Mr. Morrison's species 

 of Polio. In medialis the male antennae are bi-pectinate, but the pec- 

 tinations are very short. In accutissima the male antennae are also shortly 

 bi-pectinate. In Pachypolia atricomis the head is more sunken and the 

 male antennae are lengthily bi-pectinate. I do not know at this writing 

 either Mr. Morrison's confragosa or his spedosa, and from his descriptions 

 do not think that I have seen them. 



I am not certain that the eyes are unlashed in our species, but I can 

 not make the lashes out with certainty. Lederer calls the eyes unlashed 

 in Hadena, and lashed in Polia. So long as the corporal tuftings are used 

 as generic characters we shall have some uncertainty as to the best position 

 of many species belonging to the Hadenoid group, until we have series 

 of bred specimens of our species. 



Polia illepida, n. s. 



$ °. . The male antennae are bi-pectinate, ciliate. Thorax with 

 inconspicuous tuft in front and behind. Abdomen apparently without 

 tufts. Eyes naked, unlashed (?) ; tibiae unarmed. Size rather large ; 

 wings elongate. Hind wings of the male white or whitish ; of the female 

 gray or smoky ; an even mesial shade band more or less apparent ; veins 

 a little darker ; a terminal line. Beneath whitish or gray with obsolete 

 marks. Fore wings dark gray. Reniform rather large, curved, sometimes 

 a little brighter tinged, pale gray, with an interior darker shading, ringed 

 with dark; orbicular pale gray, spherical, rather "small, not constant in 

 size, blackish ringed. Lines even or' very little denticulate, single, more 

 or less indistinct and obliterate, except the subterminal, which is blackish, 

 jagged, running obliquely inwardly from below apex to between veins 4 

 and 5, thence outwardly, and from vein 3 again inwardly to within internal 

 angle. T. p. line followed by a pale gray shade. Fringes of primaries 

 gray, paler at base ; a fine dark terminal line and small blackish points.
