 Synopsis of tin' Species. 

 A.. Fore wings entire; hind wings not angulated : 



Outer line deeply sinuous, waved. Insect tinged with ochreoua S. s-tignata. 



Outer line straight ; three costal spots, succeeded by three rows of vennlar spots; 



pale gray S. caJiforniata . 



Like californiata, bui the antennas pectinated ; a broken patch in the middle of the 



wing ; hind wings with a dark line S. dislocaria. 



B. Fore wings slightly falcate; hind wings slightly bent: 



Diseal dot forming a ringlet ; lines replaced by venular black dots. Pale gray. . . S. ocelUnnta. 



Like preceding, but suboohreous, and head and prothoraz reddish-ochreous S. punctolineata. 



Granite-gray; coarsely speckled; large brown costal spots, and a mesial brown 



patch under the large costo-apical patch S. granitata. 



C. Fore wings decidedly falcate; hind wings with a prominent angle: 



Fore wings with seven lines; bind wings with four. Pale gray S. multilineata. 



Whitish, tinged with ochreous ; an extreme median, eye-like, large, deep-ochreous 



patch under the brown costo-apical patch 5. enoiata. 



Same color as preceding, but with no eye-liko patch, and three slight lines on fore 



wings &• galbineala. 



Half as large as preceding, with three lines ou hind wings; very pale beneath S. minorata. 



Twice as large as minorata, with border of both wings dark lilac-gray; a broad, 



common, ochreous band beneath S. prcvatomata. 



Dark lilac-gray, with the lines blackish, and with a submarginal, chocolate, com-

6 i and 4 9 . — The outer edge of the fore wings is not excavated, and hind 

 wings not angulated ; it differs from all the other species known to me by 

 the distinct, dark, clear sigmoid line crossing the outer third of both pairs of 

 wings. Body and wings tawny-ash, head a little darker than the body; front 

 of head, palpi, and antenna; tawny-yellow. Fore wings densely speckled 

 with brown, with four prominent brown spots on costa ; the two.inner being 

 the termini of an indistinct row of venular dark dots, the second including 

 the diseal dot. The third line represented by a distinct s-shaped wavy black 

 line, sometimes, but not usually, reaching the costal dot. Beyond is a broad 

 dark shade running across the wing. Half-way between the sinuate line and 

 the edge of the wing is a white interrupted line. The usual black points on 

 the edge of the wing. Hind wings (usually) with a single sinuate distinct 

 brown line crossing the wing; beyond, a broad brown shade, succeeded by 

 an irregular whitish line often obsolete. Beneath with an ochreous tinge; 

 densely speckled ; the line faintly reproduced. Submarginal broad band dis- 

 tinct ; diseal dot on hind wing large; on fore wing it is indistinct.
