rapi.lly convergins; to behind cell, then continued narrowly almost brokenly to 

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

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

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

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

 neath as above, but more indistinct, the costa of fore wings being black from base 

 to beyond middle field. 



Colorado. 



T. obscurior n. sp. — Expands 26-30 mm. Palpi, thorax and abdomen fus- 

 cous black ; palpi short, slender; fore wings blackish 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 

 opposite discal spot 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. 



California, Colorado. 



T, bivittata. n. sp. — Expands 26 mm. Palpi ocher fuscous; thorax, clypeus 

 and abdomen dark fuscous; fore wings rather dark fuscous, slightly ocher tinged, 

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

 obsolete cross-lines; discal spots distinct, black, round; a whitish longitudinal 

 dash on both sides ; two outer marginal lighter lines very faint, running parallel 

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

 cous at base, darker outwardly and along inner margin, a number of dark lines 

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

 beneath as above, less uniform, a dark outer line showing on fore wings rounded 

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

 discal spots distinct on all wings. 



Mendocino, Cal., June. 



T. unicolor n. sp. — Expands 26-28 mm. Palpi fuscous ; head, thorax and 

 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 

 light fuscous, discal spots and outer line showing more broadly than above. 



Colorado and California. 



T. cestata n. sp. —Expanse 28-30 mm. Palpi blackish or dark gray whitish 

 at end ; face black below, whitish above ; thorax gray or whitish. Abdomen 

 dark fuscous, intermixed with gray 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 spot 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 spot, with another at anal angle, these sometimes continuously joined as
