Primaries yellowish white with a li.uht brown or gray brown subcostal 

 shade. Wins in paler areas marked with a similar color. Fringes concolorous. 

 Under surface mostly gray-brown, but with the lobes as above, with dark veins. 

 Secondaries and their fringes pale brownish gray. Expanse 20-27 mm. 



Distribution: Type locality Williams, Ariz. Miss, to Ariz., north 

 into S. Cal. and Utah, Mar. to May, July, Sept. 



Like the related species, caudelli seems to be poorly defined. We 

 have only a small series, but it includes a very considerable range of 

 variation in depth of color and prominence of markings. A specimen 

 from Jemez Springs, N. M., is very close to the type, which we have 

 examined, but two others from the same lot diverge, and our Utah 

 specimens approach auslralis Grin. The genitalia differ from that 

 species, and also from those of catalinac Grinnell (agraphodactylus 

 Auct. ? Walk.) with which caudelli seems also to intergrade in ap- 

 pearance. Unicolor B. & McD. may be based on a dwarfed specimen 

 of caudelli, but the type and one other 9 which we refer tentatively 

 to that species have the abdomen more distinctly striped than the series 

 which we are calling caudelli. 



The life history is unknown.

 This species is so nearly the counterpart of caudelli that a description 

 would be mere repetition. We have only six specimens. These average a little 

 larger than caudelli and are slightly more yellow, with the brown subcostal 

 shade running back to about the middle of the base of the wing. Just within 

 the co.stal margin of this shade is a slender line of ground color along the mar- 

 gin of the cell. \\'e should hesitate to regard the two species as distinct but 

 for the fact that the male genitalia differ conspicuously. Our series expands 

 25-27 mm., the t>-pe 28 mm.
