SCOTOGRAMMA Smith, geu. nov. 



Eyes hairy; tibia unarmed; vestiture loose, souiewliat irregular, 

 either hairy or scaly. Antenna of $ simple. Form moderate; wings 

 ample; primaries trigouate, with marked apices and oblique outer 

 margin. The head is retracted ; the palpi well developed, always ex- 

 ceeding front. Thorax with usually an indefinite anterior and pos- 

 terior tuft ; abdomen not, or very indefinitely, tufted. This genus has 

 no strong characters, and is almost entirely a negative one. Of only 

 one of the five species {snhmarina) is the S known, and this species is 

 to be considered the type of the genus. 



In habitus these species resemble nothing more than themselves. 

 They are obscurely colored and marked, rather loosely put together, 

 and while possessing most of the characters of Mamestra, evidently 

 rank much lower in the scale. 



Suhmarina, the type of the genus, was described by Mr. Grote as au 

 Anarta, but it has round eyes, and such an evidently diflerent appear- 

 ance and habitus that the reference can not under any circumstances 

 be maintained. 



Fhoca, Mr. Moeschler refers to Mamestra rather doubtfully. Mr. 

 Morrison redescribed the species as 3L pronmlsa, and Mr. Grote referred 

 the latter to Anarta. 



The remaini'ng species are new, and while some of them have been 

 in collections for years the impossibility of definite generic reference 

 and want of strong characters has prevented their description. 



S. perplexa Suiitli, sp. uov. 



Primaries dull, fuscous gray, all the maculation indistinct. Median 

 lines barely traceable ; t. a. angulated ; t. p. dentate. S. t. line marked 

 by faint pale powderings, not defined. Orbicular large, oval, with pale 

 powderings. Eeniform scarcely traceable, marked by a few pale scales. 

 The claviform is faintly indicated. Secondaries evenly fuscous. Be- 

 neath dark, powdery, without line or spot. Head and thorax concol- 

 orous with primaries, abdomen with secondaries. Expands 1.5 inches 

 (37'"'"). 



Habitat. — Colorado. 



The type is a unique 9 in the collection of Mr. Tepper. The thorax 

 is rather slight, the vestiture divergent, loose. The uniform dark pow- 

 dery gray primaries sufficiently characterize this species. 



S. inconcinna Smith, sp. nov. 



Primaries dark fuscous, with black powderings, all tlie lines and or- 

 dinary spots distinct. Basal line geminate, black. T. a. line obsoletely 

 geminate, inner portion ftiint ; slightly arquate, outwardly curved in. 

 the interspaces. T.p. line geminate, parallel with outer margin, with 

 dents on the veins, followed by pale points. S. t. lijie irreguhir, pale, 

 punctiform, accompanied by blackish shades. A row of black terminal
