Beueatb, primaries with blackish disc and broad, pale terminal space; 

 secondaries pale ocbreous, with brown powderings, outer shade line and 

 discal spot. 



Expands 40 millimetres = 1.60 inches. 



ElABiTAT. — Colorado. 



The unique 9 type from Mr. Hulst's collection was before me. The 

 species is so well marked that there is no possibility of mistaking it.*

Pale, livid, or somewhat violet gray, the median space more red brown, 

 a slight crimson suffusion in costal region of basal space, and a larger, 

 darker shade fills the costal region of the s. t. space. Terminal space 

 somewhat darker gray; a distinct black basal streak. Basal half line 

 geminate, faint. T. a. line geminate, inner line more or less obsolete, 

 outer line blackish, darker toward inner margin ; its course outwardly 

 arcuate, T. p. line geminate, black, outer line punctiform or obsolete; 

 somewhat outwardly bent over cell, and with a small inward line to hind 

 margin. S. t. line faintly marked by a slight diffei euce in shade between 

 s. t. and terminal spaces : a row of black terminal luuules. Claviform 

 small, black ringed. Ordinary spots large, black riuged; orbicular 

 oblique, often with a narrow v.hite interior annulus; reniform, with 

 broader distinct white annulus, interiorly wiih black powdery filling. 

 Secondaries smoky fuscous, paler toward base; a row of black terminal 

 lunules. Beneath powdery,disc of primaries dusky, outer margin broadly 

 pale; secondaries paler, with median transverse darker line; both wings 

 w ith darker discal spots. Head and thorax concolorous with primaries, 

 the tuftings distinct; dorsal tuftiugs of abdomen distinct. 



Expands 36 to 39 millimeters = 1.44 to 1.76 inches. 



Habitat. — Middle and Eastern States, Canada, Colorado. 



The European examples differ from the American variety by less defi- 

 nite maculation and more even and less contrasting color. Still I think 

 there is no question as to their specific identity, though the name Jini- 

 tima may be retained as applying to our American race. 



Group sputatrix. 



In this group all the maculation becomes indistinct or obsolete, the 

 ground color is even, and there is no contrast except in the reniform, 

 which is more or less white or pale powdered. In structure the species 

 do not differ from the devastatrix group. 



*Mr. Bruce sent me iu February, 1891, a single specimen in a lot for determina- 

 tion. The maculation is like the type but the colors are more sordid throughout.
