Primaries red browu ; costa aud collar inferiorly yellowish ; collar 

 tipped with black ; cell around the ordinary spots black. Transverse 

 lines geminate ; t. a. line not crossing costal pale space, else distinct; t. p. 

 line panctiforui, barely traceable 5 s. t. line pale, interrupted, iiowdery. 

 Ordinary spots pale-ringed, orbicular invaded by costal pale space; 

 reniform slightly cinereous ; claviform faintly outlined in pale. Abdo- 

 men and secondaries smoky fuscous. Harpes of S short aud broad, 

 superiorly prolonged into a cylindrical finger-like process ; inferiorly 

 into a short acute spur. The clasper consists of a single curved hook 

 from the superior portion of harpes. 



Expands 38™"^ ; 1.5 inches. 



Habitat. — California, Washington. 



This is the exsertistigma of the Edwards collection, and like one speci- 

 men so labeled in Mr. Tepper's collection. The typical exsertistigma 

 is, as Mr. Morrison described it, much like alternata in color and ap- 

 pearance. 



The primaries are also more produced and have the outer margin 

 more oblique, apex rectangular. The body is not depressed. The 

 harpes, as compared with/orwmii.5, difier in the produced inferior angle 

 and the comparatively shorter and less curved clasper. 



The species seems not rare.

" 9 Fore tibire unarmed; middle and hind tibiie spinose. By the flat- 

 tened abdomen allied to cupidissima. Fore wings dark blackish brown, 

 with the terminal space x)aler, somewhat olivaceous. As in exsertistigma, 

 the orbicular is open, triangulate, broadly pale margined, fusing supe- 

 riorly with a pale subcostal shade extending from the base of the wing 

 above this spot. Unlike exsertistigma, the orbicular and reniform are 

 black, the ground color of the median si)ace about them being powdered 

 with deep yellow. A black basal dash before the geminate, waved t. 

 a. line; the latter interrupted by the subcostal shade, and with an inte- 

 rior pale shading. Claviform moderate, pale-edged. T. p. geminate, 

 the inner line scalloped, the outer even, inclosing a rather broad pale 

 space; the line is very slightly sinuate, not depressed opposite the cell. 

 Subterminal line nearly straight, dark, with a very pale powderj' exte- 

 rior shade. Subterminal space darker shaded on costa, relieving the
