Pale tawny or brownish white. Front with a slight prominence. Antennae 

 with a brown line above. Palpi moderate, whitish above; second joint rather 

 tliick, obHqiie, third slender, porrect. Abdomen often with dorsal and lateral 

 dots in hind margin of segments, the former single and often connected by a 

 faint hne. Legs shaded with brown inside, spurs rather short. 



Primaries concolorous with body, with scattered white and brown scales. 

 The brown scales often form a streak in the first lobe and lines along the 

 veins in the second. There are two brown dots before the cleft, one scarcely 

 inside of it, the other well toward costa. The latter is larger, rather diffuse, 

 often connected with the nearest brown costal spot. From each a line of brown 

 scales runs toward base of wing, the inner usually finer, sharper and longer. 

 Cell sometimes with a brown dot. Costa of first lobe with two vague brown 

 spots and whitish fringes. Fringes otherwise gray-brown with dark tufts at 

 and before apex of first lobe and three on outer margin of second. Anal angle 

 of first lobe indicated, of second fairly well developed. Secondaries and fringes 

 similar to ground color of primaries; slightly darker. Expanse 13-18 mm. 



The male genitalia are very simple, much as in AciptUia 7valslng- 

 Iiami, but the insect is otherwise a Stenoptilia in structure. 



Distribution: S. Cal. May, June, Oct. Ariz., Apr., June. N. M., 

 July, Aug. (U. S. N. M.). Miss., Sept. (Benjamin). Fla., May. 

 The species was described from a specimen taken near Mt. Shasta in 

 July. Apparently the complete range is that which seems to be common 

 in the family, viz., the West coast south through Arizona and east 

 through the Gulf States into Florida. 



The species may be easily recognized from Lord W'alsingham's 

 description and figure, but for greater certainty we have had a speci- 

 men compared with the unique female type, now in the British Mu- 

 seum. 



The life history has never been worked out.
