The moth conforms very closely to. the description given by Pack- 

 ai'd.* In the female from which the eggs were obtained, the median 

 band on the secondaries which in the male consists of approximate 

 orange spots, becomes a continuous orange band from its enlarge- 

 ment at the C(^stal maro^in to near the internal maro^in (one-third 

 of the distance between it and the submedian), constricted opposite 

 the cell and on the first median nervule ; the nervules which intersect 

 it are dotted with black scales. On the fold between the median and the 

 submedian nervures, is an orange vitta, attenuated anteriorly for two- 

 thirds its length, enlarged and rounded posteriorly, and extending 

 nearly one-half the distance across the wing, f The sides of the 

 abdomen, terminal segment and anal tuft are orange, concolorous 

 with the ground of the posterior wings ; the black of the dorsum 

 extends medially in a point over the terminal segment. Expanse of 

 wings 2.80 inches ; in the male 2.i0 inches.

 male taken on the northern shore of tke lake, nor in a male of my collection.
