110 WM. H. EDWARDS. 



Upper side deep fulvous, spotted with black; the Iiind niarj^ins of 

 primaries fuscous, preceded by a series of rather indistinct yellow 

 lunules, near the apex somewhat replaced by white ; the sub-apical 

 patch and that at inner angle dull ferruginous ; the spots arranged as 

 in the allied species; secondaries have a broad marginal border, the 

 outer portion fuscous, the inner ferruginous, and containing a series 

 of small yellow lunules; a large black patch on middle of costal mar- 

 gin confluent with a spot at end of cell; fringes fuscous at ends of 

 nervules, yellowish in the interspaces. 



Under side brown over basal area and along the hind margins, paler 

 across the discs, grayish sub-apically, and wholly streaked with darker 

 brown ; the extra-discal points black ; within the incision of primaries 

 and along the whole margin of secondaries a series of narrow blue- 

 green lunules edged by black; in the darker examples these lunules 

 are scarcely discernible; silver spot small, narrow, right-angled, the 

 extremities pointed ; sometimes the lower limb is thickened; and some- 

 times the upper limb is slightly bent. 



Body brown-fulvous, below gray-brown, light on the abdomen; legs 

 gray-brown ; palpi black in front, gray with fulvous hairs interspersed 

 at the sides; antennae brown above, ferruginous below; club black, 

 tip ferruginous. 



Female. — Expands 2 inches. The extra-discal region paler than 

 the basal; the submarginal spots much enlarged, lanceolate, indistinct. 

 Under side as in the male, the markings often much obliterated; silver 

 spot as in the male. 



Found in California and Oregon, and allied to Progne. I formerly 

 described this species from scanty material, but as I have received 

 from Mr. Edwards a full series in both sexes, I have thought it well 

 to rewrite and amend the description. 



Tbecla Siva, n. sp. 



Male. — Expands 1 inch. Upper side castaneous, slightly brown at 

 base, the costal margin of primaries and both hind margins rather 

 broadly bordered with fuscous; secondaries have two tails, the outer 

 one short, the other long, .IG inch, both dark fuscous, tipped with 

 white; fringes fuscous. 



Under side light fulvous, washed with pale metallic green, densely 

 on the costal and upper part of hind margins of primaries, and over 

 the whole of secondaries ; a common pure white band crosses the discs 

 of both wings, on primaries a little convex outwardly, and formed of
