Grapta'Zephyrus, n. sp. 



Size and form of Gracilis. 



Male. Expands two inches. Upper side deep red, fulvous at base, 

 fading into pale orange on disk ; on primaries a subapical fulvous 

 patch, another at inner angle j on secondaries the outer limb partially 

 covered by fulvous in form of an interrupted transverse band, within 

 which are yellow or soiled white submarginal spots; a similar row of 

 spots on primaries; the black markings as in Gracilis and Progne, the 

 spots small, well defined. 



Under side hoary, covered throughout by fine brown streaks, most 

 densely next base ; the incision of primaries edged by a brown band, 

 on the anterior edge of which are a few scattered olivaceous scales and 

 a black line ; silver mark narrow, bent at an obtuse angle, attenuated 

 below. 



Body above fulvous covered with greenish huirs; beneath grey ful- 

 vous ; palpi white, fulvous on upper side, with a black line beneath ; 

 antennae brown above annulated with grey beneath ; club brown tipped 

 with ferruginous. 



From 2 S taken at Virginia City by Henry Edwards, Esq.. in 1869. 

 Also received from Colorado, and from Fort Simpson, McKenzies 

 River. 



This species is nearest Gracilis; is paler colored above, and nearly 

 uni-colored beneath, whereas in Gracilis the basal third is dark, and 

 the hoary space is confined to the disk ; in that species also the seconda- 

 ries have a submarginal black band with green lunules which is want- 

 ing in Zcpliyrus. 



Grapta Marsyas, n. sp. 



Form of Comma, much smaller; primaries scarcely falcated, much 

 excised; on secondaries a long and very broad tail, posterior to which 

 is a deep incision and a prominent dentation ; anal angle produced. 



Male. Expands l.G inch. Upper side fulvous, ferruginous at base; 

 marked and spotted with black as in Comma; a common, submarginal 

 row of yellow lunules; the marginal border of secondaries ferruginous, 

 much sprinkled with yellow scales. 



Under side in shades of brown and olivaceous, the ground color 

 quite dark, the pattern of markings very much as in Comma; the 

 common discal band not distinct; the extra basal space densely streaked 

 with ferruginous; on costa of primaries a large whitish patch enclosing
