the outer marjiiii or a little siunnted. eiiipliasized by tbe smoky shade 

 through which it runs. A series of black terminal luniilcs, fringes 

 pale, cut with smoky brown. There is a ditliise, oblique, broad, smoky, 

 median shade, which is variably evnleiit and nsually involves the reni- 

 form. Orbicular a small yellow dot, which is never ])rominent and 

 often obsolete. Eeniform a small yellowish line or lunule, sometimes 

 almost obscured by the dusky median shade. Secondaries gray or 

 whitish at base, darkening to smoky or blackish outwardly; with an 

 extra median, rather even, darker line, and a ])ale, irregularly denticu- 

 late, subtermmal line, througli the darker outer region. A series of 

 black terminal lunules. l>eneath gray, black powdered, darkening out- 

 wardly; with a more or less complete dusky extra median line and a 

 more evident, i^ale, subtermiual line, repeating the upper side on both 

 wings. A more or less marked discal lunule, sometimes obsolete on 

 the primaries. 



Expanse ot wings, 20 to lit mm. = 0.80 to 0.85 inch. 



Habitat. — Florida, Archer, in March and April; Texas, in March. 



Both sexes are at hand, and are similar in ai)pearance. It has been 

 imjiossible for me to find a single permanent diflcrence in nuirking 

 between this species and the two others. It is paler tlian T. lixdlis and 

 darker than T. p((lli<jcr((, wider winged than the former, narrower than 

 the latter. The structuial diftereuces have been already noted, and 

 with both sexes at hand no trouble need be found in recognizing the 

 species. It is probably not rare in its range, which, thus far, is con- 

 tined to Florida and Texas. It will i)rol)ably be found in the other Gult 

 States. This is the species, a specimen of which I rather doubtfully 

 referred to T. pHUi<jera when describing the latter species, and whose 

 distinctness is again suggested in Bulletin 44, United States National 

 Museum, 385. 



The types are in the collection of the United States JSIational Museum.

Ground color a dirty powaery luteous, with a more yellowish suffu- 

 sion ill some specimens. Head and thorax concolorous, the abdomeu 

 somewhat paler, and with rather feebly marked ])aler wings. Primaries 

 Avith the markings all obscured, the suV)terininal line which runs 

 through a darker terminal si)ace the only distinct feature of the wing. 

 The markings are like those described for the previous species, 

 and the present differs mainly in its larger size,i)aler ground, and more 

 obscure maculation. 



Expanse of wings, 21 to 25 mm. ==0.85 to 1 inch. 



Habitat. — California: Napa County; Panamint Valley in Aprii; 

 Knightly Valley.
