THE CANADIAN ENTOMOLOGIST. 



black line, before which, at outer angle to median, is a black border like 

 that of primaries ; in the two median interspaces, next margin, a round 

 black spot to each ; sometimes an obscure similar spot in the next inter- 

 space above, but usually the black border extends quite to median ; also 

 at inner angle, in some examples, are traces of two small black spots ; 

 primaries have a black streak on arc of cell ; fringes long, on primaries 

 pure white externally, fuscous next margin, on secondaries white, with a 

 few fuscous hairs at the end of the nervules. 



Under side white, not quite pure, rather grayish, with a very slight tint 

 of blue at base of secondaries ; both wings have the hind margins edged 

 by a pale brown line, crossed by two rows of black spots, one sub-mar- 

 ginal, the other extra-discal ; these last small, and in the median inter- 

 spaces of secondaries have on the posterior side small patches of fulvous ; 

 the inner row has usually rounded spots, but occasionally nearly all are 

 elongated, disposed as in the allied species ; on the arc of cell of each wing 

 a rather large black bar ; secondaries have three spots across basal area? 

 one on costal margin, one in middle of cell, and one on inner margin ; in 

 addition to the above described spots is a common marginal row on prim- 

 aries not clearly defined, rather pale brown discolorations than spots, on 

 secondaries distinct, the outer ones brown, the rest black. 



Body above covered by long whitish-blue .hairs; beneath white, the 

 thorax with faint blue tint ; legs white ; palpi white, with hairs in front 

 tipped with black ; antennae black, with narrow white wings ; club black 

 above, ferruginous below. 



Female. — Same size. 



Upper side russet on disks to marginal borders ; sometimes much ob- 

 scured by darker brown ; in one example under view the disks and whole 

 surface are black-brown, with an illy-defined brown patch at inner angle ; 

 but this, as well as all others, have a fulvous sub-marginal belt on second- 

 aries, on the marginal side of which are round black spots like those in 

 male; in some examples the belt is diffused towards disk; primaries have 

 the discal spot rather larger than in male ; the fringes soiled white. 



Under side brown-buff, uniform ; marked as in the male, all spots 

 rather larger ; the thorax beneath gray, with many brown hairs ; abdomen 

 nearly color of wings. 



The species is allied to Scepiohis, Bd., as well as to Icar aides, and the 

 plan of markings of under side is similar in the three. It differs from 

 Scepiolus most decidedly m color of upper side of male, the latter being of
