Three males, with the abdomen pruinose, and a female from the 
Isthmus of Tehuantepec by F. Sumichrast, in the M. C. Z. The 
female differs somewhat from those described from Baja California 
in having the wings throughout faint yellowish instead of the 
apex only, and the streak in the submedian (median of previous 
nomenclature) space is deep yellow, not dark brown as are the sub¬ 
costal streaks. As variations in neuration it may be noted that the 
postnodals on the front wings vary from 6 to 9, on the hind wings 
from 7 to 10 , internal triangle of one cell on one front wing of one 
male, of three cells on one front wing only of one male and the 
female. 
A female from Tepic, November, 1894, by Eisen and Vaslit (coll. 
Cal. Acad. Sci.), with many of the green spots changed to red in 
some way, belongs here and agrees with the female from Tehuantepec 
in the colors of its wings as above described.

ber, Tepic and Tehuantepec as above.
