ate and bisinuate. Clasper as in muricina. Expands 1.28 iuches 

 (32 ,,,ni ). 



Habitat.— Nevada. 



Apparently a close relation of muricina,, but at once separable by the 

 concolorous terminal space. A single male specimen (tbe type) is in 

 Mr. Edwards's collection. 



Perigrapha muricina Grt. 



Buf. Bui., 1875, 3, 85 (Acerra); C. E., 1879, 11, 27 (Graphiphora) ; id., 1881, 13, 133 

 ( Perigrapha). 



Pale brown, with grayish suffusion in basal, s. t. and lower part of 

 median space. Terminal space gray. Ordinary spots confluent in the 

 form of a wide ~\T ; whitish gray, reuiform with a rnsty shade line ; out- 

 line inferiorly and at sides, black. Basal line distinct, single, brown. 

 A short brown basal dash. T. a. line narrow, single, outwardly curved 

 between veins. T. p. line faint, slightly marked on veins, but hardly 

 traceable except for the faint difference in shade between median and 

 submedian space. S. t. space narrow, sharply defined outwardly by 

 the even gray terminal space. ' S. t. line irregular, interrupted, brown ; 

 best marked atcosta and internal margin where it bounds the pale ter- 

 minal space. A row of slender brown terminal lunules. Secondaries 

 even, fuscous. Beneath reddish, powdery, secondaries with extra discal 

 line. Head and collar brown, the latter with darker tip. Teguhe and 

 tuftings gray, with brown tips. The harpes of male are slender, gradu- 

 ally enlarged into an obtuse lappet, which is inwardly sparsely spinu- 

 lose. Clasper bifurcate, the inferior branch straight, stout, regularly 

 tapering to tip; the superior branch curved, subequal. Expands 1.30 

 inches (33 mm ). 



Habitat.— Oregon. 



Readily distinguished by pale brown color, and the contrasting ter- 

 minal space. The type is with Mr. Edwards. 



Perigrapha Behrensiana Grt. 



C. E., 1875, 7, 71 {Graphiphora), id. 1881, 13, 133 (Perigrapha). 



" * * * The fore wings are coarsely irrorate with black, of a dull 

 brown ground color, darker to the pale subterminal line, beyond which 

 they are paler, with the veins pale marked. The costal edge is car- 

 ueous. The lines are pale, tolerably approximate on internal margin, 

 rather even, with blackish margins. The t. a. line outwardly oblique, 

 the t. p. line flexuous. Ordinary spots large, pale margined, fused, so 

 that there is a resemblance to some species of Glaea. Hind wings 

 soiled white, sparsely irrorate, with a discal dot, concolorous fringes 

 and a broken terminal line. Beneath whitish, a continuous line on 

 primaries, dotted on hind wings ; discal marks double on fore wings 5 

 very distinct on secondaries,"
