4G4 NORTH AMERICAN NOCTUID.E SMITH. 



inner portion faint. Slightly arcuate, outwardly curved in the inter- 

 spaces. T. p. line geminate, parallel with outer margin, with dents 

 on the veins, followed by pale points. S. t. line irregular, pale, puncti- 

 form, accompanied by blackish shades. A row of black terminal lu- 

 nules. Secondaries blackish fuscous, with pale fringes. Beneath dark, 

 powdery, with indistinct discal lunule. Head and thorax concolorous 

 with primaries; the thorax with indistinct fore and aft tufts. Abdo- 

 men with a distinct, truncate tuft at the first segment. The terminal 

 segment of female is as in submarina. Expands 1.40 inches (35 mm ). 



Habitat.— Colorado. 



The type is a female in fair condition. Ultimately it may prove re- 

 ferable elsewhere, when the male is studied, but its habitus and general 

 structure seem rather to place it with submarina, and the structure of 

 the last segment of the female abdomen confirms the reference. The 

 vestiture is a mixture of scales and flattened, hair, and the thorax in 

 form is quadrate. The frontal vestiiure forms two superimposed tufts. 

 The species seems thus more nearly allied to Mamestra, while differing 

 obviously from any species known to me. 



Scotogramma umbrosa Smith. 

 Proc, U. S. Nat. Mas., 1887, x, 470. 



Dark, blackish gray, powdered with white scales. All the macula- 

 tion present, though not prominent. Median and basal Hues geminate, 

 the defining lines faintly marked, the included space powdered with 

 white. T. a. line outwardly oblique, with inward dentations on veins. 

 T. p. line about parallel with outer margin tolerably even. S. t. line 

 irregular, pale, punctiform, somewhat obscured by the pale powder- 

 iugs which are most numerous in the s. t. space. An interrupted dark 

 terminal line. Claviform distinctly outlined ; concolorous. Orbicular 

 moderate, round, with white powderings. Reniform large, upright, 

 pale powdered, well defined. Secondaries blackish, paler toward base. 

 Beneath variably dark, powdery, with outer dark line and small dis- 

 cal spots. Head and thorax concolorous, with primaries. Expands 

 1.20 to 1.30 inches (30 to 32"""). 



Habitat. — Arizona, Colorado. 



Three female specimens are before me. The vestiture is scaly, and 

 the tufts of thorax, abdomen, and front are like those of inconcinna. 

 There is no special modification of the last segment of the abdomen.

 Hy. Eclw., Cau. Eut., 1887, xix, 140. 



"With much of the general appearance of Perigea falsa, Gr., but 

 said by Mr. J. B. Smith to belong to his new genus Scotogramma. 

 Dark stone drab, the lines blackish, all much confused, and the ground 

 color of the wing covered with brownish irroratious. Basal half line
