are also armed with clusters of slender, hooked hairs. The caudal end is sharply 

 pointed, but there is no distinct cremaster. 



"The larva is an external feeder, and the pupal period is very short. Larvae 

 collected by Diven from April 7 to 14, 1919, produced moths as early as the 

 19th of the same month."

Head brown, sometimes pale ; whitish between antennae. Antennae whit- 

 ish above, darker below, sometimes with a blackish line above near base. Palpi 

 moderate, slender, oblique, whitish. Legs white; fore and middle legs, including 

 first joint of tarsi, with brownish black stripes, remainder of tarsi brown shaded 

 on inside. Thorax and abdomen yellowish, pale brownish white or tawny, the 

 last sometimes with a few small blackish dorsal spots. 



Primaries a little paler than thorax and abdomen, tawny white. Inner 

 margin of first lobe with a fine blackish brown dot before apex. Cleft preceded 

 at some distance by a similar but larger dot. In the allotype there are a few 

 dark scales on the discal area, a fine dot in the apex of the second lobe and 

 one at the tip of Cu^, which is very faint. The dot before the cleft is also 

 slightly extended across the wing. Fringes concolorous. Secondaries and their 

 fringes a little darker and more grayish. Expanse 20-21 mm. 



Described from three specimens taken at Paradise, Cochise Co., Ariz. 



Holotype S, May 8-15 and allotype, Aug., in coll. Barnes. 



Paratype 3. May, U. S. N. M. No. 23480. 



We have also a worn male from Jeinez Springs, N. M., which 

 differs in the form of the left harpe (pi. LIV, fig. 9a). We are miable 

 to say whether this indicates variability in this structure or the specific 

 distinctness of the specimen, but we believe the former possibility more 

 likely. 



The early stages are unknown.
