inner line more vague, but y€t distinct. T. p. line outcurved over reni- 

 form, then evenly oblique to the hind margin : inner line black, narrow, 

 crenulate, outer line scarcely defined, even. S. t. line sinuate, broad, 

 rather diffuse, slightly paler than the ground color, outwardly marked 

 by a few black scales. A row of terminal lunules, median shade vague, 

 marked by a costal spot and below the cell by a diffuse blackish powder- 

 ing parallel with the t. p. line. Olaviform wanting. Orbicular mod- 

 erate in size, round, black ringed, evenly paler than ground color. Ken- 

 iform moderate in size, kidney shaped, rather incompletely black ringed, 

 coucolorous or slightly paler. Secondaries white, in the male immaculate, 

 in the female with veins and Outer margin slightly soiled. Beneath 

 white, primaries powdery, with an outer line and discal spot, most evi- 

 dent in the female; secondaries in the male immaculate, in the female 

 with a distinct discal spot. 



Expands 36'""', 1.45 inches. 



Habitat — Las Vegas, New Mexico. 



A somewhat rubbed male, and a good female in Mr. Neumcegeu's 

 collection, taken by Mr. Meeske in 1889. This species is perhaps 

 nearest to hrunneigera, but distinct by the ashen fuscous color and 

 white secondaries of both sexes. It has at first sight some resemblance 

 to pale forms of messoria, but lacks the claviform. The median shade 

 is vague, and this is one of the forms in which care is required in placing 

 in its proper group. 



Carneades perturbata sp. uov. 



Rather pale luteo-fuscous in ground color of head, thorax and prima- 

 ries. Head and thorax with black scales intermixed, forming a rather 

 indefinite margin to patagiiiB. Primaries with basal and s. t. spaces 

 •paler than median and terminal spaces. All the transverse lines gem 

 inate. Basal line well marked, the defining lines equally distinct, 

 black, included space coucolorous. T. a. line distinct, inner defin- 

 ing line scarcely less marked than the outer, which is black. Its 

 course is outwardly oblique, outwardly curved in the interspaces. 

 T. p. line outcurved over cell, then nearly parallel with outer margin : 

 inner line distinct, luuulate rather than crenulate, outer line even, 

 darker fuscous than ground color. S. t. line defined only by the differ- 

 ence in shade between s. t. and terminal spaces, and marked by a few 

 irregularly placed black points ; irregular in course, quite strongly in- 

 dented on veins 3 and 4, without however resembling in other ways 

 the quadrUlentata series. A series of black somewhat lunate terminal 

 spots. Fringes with a pale line at base. Median shade line rather in- 

 distinct, upright, touching inner margin of reniform and reaching the 

 hind margin at the same point with t. p. line. Claviform coucolorous, 

 distinctly outlined in black. Orbicular rather small, somewhat irregu- 

 lar, black ringed ; somewhat paler than ground color, slightly darker 

 centrally. Reniform well sized, somewhat constricted centrally, black
