may be distinguished b}^ the usually ovate orbicular, and the strongly 

 dentate s. t. line which is often wanting. In vancouvereusis the s. t. 

 line is lunate, but tolerably even and always traceable. 

 The following table will illustrate the differences : 



Male anteiiuie distiuctly bipectiuate. 

 Terminal space, ordinary spots, auil inner margin of primaries discolorous, red- 

 dish; ground color, blackish brown cikcumdata. 



Terminal space of primaries concolorous. 

 Transverse lines and ordinary spots obvions, veins more or less relieved by paler 



streaks gladiaria. 



Transverse lines and orbicular obsolete, costal margin, claviform and A'eins 



blackish; else dirty yellowish gray venerabilis. 



Male antenuBB serrate, bristled and ciliate; not pectinate. 

 Head rather small, retracted, primaries proportionately short and narrow. Sec- 

 ondaries dnskj'. 

 Ordinary spots distiuctly annulate with pale yellow, reniform constricted, iu- 

 feriorly produced inwardly into an acute tooth often reaching the or- 

 bicular GRAVIS. 



Ordinary spots not annulate with pale. 

 Primaries somewhat narrower. 

 Orbicular round; s. t. line rather even, though somewhat variable. Claviform 

 distinct, usually black or darker than groundcolor., vancouvhrensis. 

 Macnlatiou indistinct, as in preceding; color yellowish ; anteunaj of J more 



strongly serrate, bristles longer aeneipennis. 



Primaries wider; orbicular usually ovate; s. t. line often lacking; when pres- 

 ent very irregular, strongly dentate volubilis. 



Head wider, more free, primaries proportionately longer and narrower. Second- 

 aries clear pearly white. 

 Orbicular small, round, connected with reniform by a distinct black dash. Clavi- 

 form faintly outlined annexa . 



Orbicular larger, outwardly extended; no black connecting dash; claviform 

 very large, distinct black malefida.

Thorax and primaries smoky blackish brown. Primaries with termi- 

 nal space evenly yellowish or leather brown, joining a broad band of 

 similar color along inner margin. Ordinary spots distinct discolorous 

 leather brown. Transverse lines indistinct geminate. T. a. line very 

 strongly angulate. T. p. line lunulate, its course sinuate. Secondaries 

 fuscous with reddish or violet fringes. Beneath, powdered with red- 

 dish; a common extra discal line, and distinct discal dot on each wing. 

 Abdomen browaiish fuscous, antennte yellow. 



Expands 31-34"""; 1.25-1.35 inches.

This species is so distinct that a lengthy description is unnecessary. 

 The ititroduction and synoptic table give the differences from other 

 species.
