 vein 1, then broadenino: to inner margin ; on costa the shape to narrowest part is 

 triangular, and on inner margin subtriangnlar : faintly lighter lines on each side 

 the blackish space, a wavy subniarginal lighter line; hind wings fuscous, lighter 

 at middle and base, irregularly clouded outwardly and along inner margin ; be-

T. obKCurior n. sp. — Exi>ands 2(J 30 mm. Pal])!, thorax and abdomiMi fus- 

 cous black ; palpi short, slender; fore wings blackisli fuscous or brownish, tinted 

 with faint geminate lines; outer line more distinct, especially at costa, sometimes 

 light across the wing ; it turns at nearly a right angle outward at cell, then rounds 

 opjjosite discal s])ot in nearly a straight line to inner margin ; the submedian is 

 black lined from base to middle : the submarginal line is very faint ; hind wings 

 with blackish marginal space and broken blackish inner margin ; beneath nearly 

 even blackish fuscous, with black spots along costa.

 and abdonu'ii dark fuscous ; fore wings rather dark fuscous, slightly ocher tinged, 

 unicolorotis or faintly mottled, being slightly darker on veins, the indications of 

 (tl)S()lete cross-lines; discal spots distinct, black, round; a whitish longitudinal 

 tlash on both sides ; two outer marginal lighter lines very faint, running jiarallel 

 with outer margin continuing to costa just within apex; hind wings light fus-

 soon obsolete showing along inner margin ; marginal lines in both wings black ; 

 beneath as above, less uniform, a dark outer line showing on foi-e wings rounded 

 somewhat at costa; hind wings with faint outer cross-line; marginal lines black ;

 abdomen fuscous, with a violet-red tinge ; all wings of same color, evenly frosted ; 

 fore wings with a blackish basal line making a right angle at cell ; an interdiscal 

 line corresponding in color and direction, a little more distinct ; a corresponding 

 outer line with a deep outer sinus beyond discal spot, these two outer lines con- 

 tinued on hind wings; discal spots of all wings black, not very distinct; beneath

 dark fuscous, intermixed with gi'ay scales and ringed with lighter color; fore 

 wings light gray, overlaid on all edges with fuscous black, sometimes with a 

 brownish tinge : this color following the costa from base, becoming a large trian- 

 gular sjtot at discal point and enlarging to another smaller triangular spot near 

 apex ; on outer margin it is obsolete below apex, then at middle becomes a large 

 rounded sjjot, with another at anal angle, these .sometimes continuously joined as
