of the cell half way to the wing base, and a similar dash just above 

 vein 1 ; hind wings faintly tinged with dull yellowish, the veins black- 

 ish brown. 



The sexes are similar. 



Type. — Near Cuzco, Peru, collected bj' H. A. Jaynes, of the U. S. 

 Bureau of Entomology and Plant Quarantine, now stationed at Jeaner-- 

 ette,La., 5 (U.S.N.M. No. 53528). 



Additional specimen examined. — A female, from the same locality, 

 also collected by Mr. Jaynes. 



Remarks. — This species is allied to D. 7iivosus, of which it may 

 eventually prove to be merely an extreme form. It is easily dis- 

 tinguished from nivosus hj the almost pure white hind wings and the 

 much whiter fore wrings on which the submarginal white; spots between 

 vens 1 and 2, 2 and 3, and 3 and -1 are larger, the first two reaching 

 the dark border; the spots in the dark border of the wings are also 

 larger, and the inner row is complete, the spots in this row being as 

 large as those in the outer row.
