S. pettiti Grt. 



1S75, Grt., Can. Ent. vii, ISS, Scope/osoma. 

 1877, Grt., Can. Ent. ix, 213, Scopelosoma. 

 Deep reddish yellow, all the maculation indistinct. Basal line often ob- 

 solete. T. a. line upright, often obsolete. T. p. line oblique, arcuate, marked 

 on veins with black points, which makes it seem cren- 

 ulated. S. t. line indistinct, also marked with faint 

 blackish shades on the veins. A row of indistinct 

 terminal lunules; median shade rather diffuse, always 

 distinct; slightly or not at all sinuate. Ordinary spots 

 concolorous, faintly outlined; orbicular small, round, 

 often scarcely discernible; reniform large, more obvious, with a blackish spot 

 inferiorly. Secondaries pale yellow, with a faint reddish suffusion. Beneath 

 as \n grcTjiaua and uiojfatiixna. Expands i.io inch.; 27 mm. 

 Hab. — Canada, Iowa, New York. 



This species is readily distinguished from all the broad winged 

 forms by the obsolete maculation and small size. From ceromatica, 

 its nearest ally, it is distinguished by the much more yellowish-red 

 color. 



S. ceromatica Grt. 



1S74, Grt., Buff. Bull, ii, 70, Scopelosoma. 

 1874, Grt., Buff. Bull, ii, 125, Xauthia. 



Rather dark orange-red, with violet powderings; terminal ^pots some- 

 what darker; median lines brown. T. a. line upright, or but feebly arcuate, 

 even. T. p. line parallel with, and rather close to outer margin, crenulate; 

 the points blackish. S. t. line irregular, inwardly 

 diffuse, slightly paler; outwardly limited by the 

 darker terminal space. Basal line barely trace- 

 able. A distinct, slightly sinuate median shade 

 line, touching outer boundary of reniform. Or- 

 bicular small, round, concolorous, with darker outline and a pale inner an- 

 nulus. Reniform large, kidney shaped, darker, with pale ring; inferiorly 

 there is a blackish dot. Secondaries luteous, with an orange suffusion. 

 Head and thorax concolorous with primaries. Beneath pale yellowish orange, 

 with a red-brown outer line; secondaries with discal lunule. Antennte of (^ 

 thicker and ciliate; of 9 more slender and simple. Expands 1.20 — 1.40 inch.; 

 30—35 mm. 



Hab. — New Jersey, New York, Maine, New Hampshire, Canada. 



A very distinct form, recognizable by the deep orange color and 

 violet powderings; it is the most intensely colored of the wide 

 winged species.
