black terminal lunules. Orbicular very large, obsolete, marked only by 

 two curved dusky spots ( ), indicating the outer margins. Eeniform 

 faintly outlined, interiorly dusky. Head and thorax concolorous. Sec- 

 ondaries white, with broad blackish outer margin, fringes white. 

 Beneath, primaries white with darker powderings, reproducing very 

 faintly the maculatiou of upper side. Secondaries immaculate, white. 

 The genitalia are of the same type as decepia, but the basal projection 

 is wanting; the slender hook is replaced by a short beak-like clasp, 

 and the spatulate projection is much larger and more prominent. Ex- 

 pands 1.40 inches (35 mm ). 



Habitat. — California. 



A single perfectrmale in Mr. Edwards's collection. This species differs 

 very evidently from decepta as well in structure as in maculation, but 

 is perfectly congeneric. The front is not so full ; the body is shorter, 

 more robust; the vestiture hairy, long, and the primaries are somewhat 

 more pointed. The pale terminal space well distinguishes it at a glance. 

 Many additional specimens have been since seen, and several are in the 

 collection of the Museum, taken by Mr. Koebele. 



SCOTOGRAMMA Smith. 

 Proc. U. S. Nat. Mus. 1887, x, 469. 



Eyes hairy, tibia? unarmed, vestiture either hairy or scaly. An- 

 tennre of male simple. Form moderate, wings ample; primaries trig- 

 onate, with marked apices and oblique outer margin. The head is 

 retracted, the palpi well developed, always exceeding front. Thorax 

 with usually more or less obvious anterior and posterior tufts. 



This genus has no strong characters and is almost entirely a nega- 

 tive one. Two well-marked groups are formed in it, of which the first 

 is the more typical, submarina being typical of the group and genus. 

 It is the only species of which the male is known to me. 



This first group is characterized by hairy vestiture and rather 

 smoothly clothed front. 



Submarina is luteous gray, without s. t. line, but distinct, single 

 median lines, the s. t. crenulate. The orbicular is wanting, the reuiform 

 indistinct. The male genitalia are hereafter described. 



Phoca, of which promulsa is a synonym, is nearly allied to the pre- 

 ceding, but the s. t. line is distinct. In the Labrador form (phoca) the 

 color is paler, more whitish; in the Colorado form* (promulsa) there is 

 a fuscous suffusion. 



Perplexa is an evenly powdered gray form with all the maculation 

 present, but obscured ; the presence of the claviform distinguishes it 

 from either of the preceding. 



The remaining species belong to the second section, which is charac- 

 terized by scaly vestiture, quadrate thorax and front with superim- 

 posed scaly tufts,
