defiued by a uariow deep black Hue. Secondaries white, toward the 

 margin jiowdered with a few blackish scales. Beneath, primaries 

 smoky, 1)0 wdery; an evident discal dot; secondaries white, along costal 

 margin powdered with black ; a blackish powdery discal lunule. Head 

 and thorax coucoloroiis. 



Expands ai-ST'""^ ; 1.35-1.50 inches. 



Habitat. — Canada, Middle and Eastern States, west to California. 



Distinguished by the almost uniformly black primaries and white 

 secondaries. From dark forms o^ imstoralis in which the maculation is 

 obsolete, this species is distinguished by the white secondaries, and the 

 much shorter, more stumpy iirimaries. The species is a very recog- 

 nizable one, and not uncommon locally.

Head, thorax and primaries deep smoky or blackish brown. Palpi 

 darker at sides, collar with a tip of luteous scales, thoracic crest with an 

 admixture of hoary scales. Primaries with a luteous shading through 

 the centre of the wing. All the maculation obscure, indistinct, yet all 

 traceable. Basal line marked on costa only by a geminate black spot. 

 T. a. line geminate, sometimes traceable through the cell^ somewhat out- 

 curved between veins and with a long outcurve below the internal vein. 

 T. p. line geminate, marked on costa, evenly outcurved over reniform ; 

 inner line finely crenulate, outer scarcely marked, except by the slightly 

 paler included shade. S. t. line paler, interrupted, sometimes almost 

 obsolete. Claviform present, outlined in black. Orbicular round, mod- 

 erate in size, very indistinctly outlined. Reniform rather large, normal 

 in form, slightly more leaden black, not very definitely outlined. Sec- 

 ondaries ( S ), pure white, a narrow dusky marginal line. Beneath white, 

 powdery, with an interrupted outer line and discal spot to all wings. 



Expands 31-35"^'" ; 1.25-1.40 inches. 



Habitat. — California (Neumoegen. Collection U. S. National Mu- 

 seum). 



This seems the California representative of vellcripcnnis which is also 

 said to occur there. A large series in the Museum collection is all ref- 

 erable to this species. I shall not be at all surprised, however, if it 

 prove but a geographical race of the Eastern form. The ground-color 

 is more luteous and powdery, and the maculation is more distinct than 

 in its ally.
