It is less bright in its coloration, ihe first lobe being a grayish-brown to 

 the base of the wing. 



Stenoptilia Coloradensis, Fernald. — Fernald, Pterophoridse of North 

 America, p. 6r, 1898. (Four examples from Colorado.) 



I have seventeen specimens in my collection from Santa Ana River, 

 5,500 ft. altitude, July and August, 1907, and South Fork, 6,200 ft. alt., 

 June 19, 25, 1907, in the San Bernardino Alts., Calif.; J. Grinnell. Not 

 previou^ly reported from any locality, except the type locality. 



Stenoptilia Califorjiica, n, sp. — Expanse of wings, 28 mm. General 

 colour buff to ochraceous-buff. Head, palpi and antennae of an even buff. 



Fore wing with a heavy, comparatively large, tawny dash at the base 

 of fissure, barely touching the fissure, extending to the costa in a broad, 

 diagonal, somewhat lighter shade ; this band directed costo-apically ; the 

 costal end of the band is a very heavy tawny dash. The rest of the wing 

 an even general colour, buff-ochraceous, except the apex of the first lobe, 

 which is somewhat darker. The hind wings are an even colour, but lighter 

 than the fore wings, of a silky lustre ; fringes concolorous. Under side 

 similar to the upper, but lacking the dash and streak on the first lobe of fore 

 wings. Thorax and abdomen the same colour as adjacent parts of the wings. 



Habitat : Santa Ana River, 5,500 ft. altitude, Aug. 2, 18, 29 ; South 

 Fork, 6,200 ft. altitude, July 10, 1907, San Bernardino Mts., by J. Grinnell, 

 and Pasadena, Los Angeles Co., Calif, Aug. 24, 1907, collected by the 

 author. A very beautiful species. 



Stenoptilia Gorgoniensis^w. sp. — Expanse of wings, 24-26 mm. Head 

 and palpi light salmon-buff; antennse darker, inclining to cinnamon-rufous. 



General colour of wings salmon-buff, darkest toward the costa ; this 

 colour is fairly even over the fore wings, except that the costal region, 

 especially basally, is very much darker; the fringes are lighter, and there 

 is a darker, fimbriate, marginal line, inconspicuous ; a conspicuous, dark 

 brown dash, basad of the fissure, and somewhat below it ; there is a small, 

 black dot in the anal angle of the second lobe. The hind wings are prac- 

 tically of the same even colour as the fore wings, and also the fringes, with 

 a silky lustre. The under side is somewhat lighter, slightly suffused with 

 grayish scales, and lacks the black dash on the fore wings. I'horax and 

 abdomen light salmon-buff; legs and spurs grayish-white. 



Habitat : South Fork, Santa Ana River, 6,200 ft. altitude, San 

 Bernardino Mts., Calif, J. Grinnell, July 4, 1907. Described from two 

 examples, taken within the San Gorgonio quadrangle (U. S. Geological 

 Survey). Types in the author's collection.
