C. STRIGOSA. n. S. 



$. Entire insect dark cream color, with a tinge of yellow 

 ochre. 



Anterior wings with a moderately wide band, concolorous 

 with the rest of the wing, defined by two rusty lines, straight, 

 somewhat wider apart on the costa than on the inner margin, 

 and both strongly bent towards the base of the wing on the 

 costa. Terminal space about one and a half times the width of 

 the band. Fringes of both wings distinctly interrupted with 

 rusty scales at the nervules. 



Beneath, the primaries are suffused with pale rusty scales, 

 and all the wings are crossed by a distinct sinuous reddish brown 

 line, that on the primaries corresponding to the outer dark line 

 above. ? unknown. 



Expanse of wings $. 1.25 inches; length of body 0.60 inch. 



Habitat. Yosemite Valley, California. Hy. Edwards. 



This may possibly be a variety of C. constricta, but I have 

 given it here as specifically distinct because there is no difficulty 

 in separating the imagines, though they resemble each other 

 closely. The question cannot be considered settled, however, 

 until we know the transformations of this species. It differs from 

 constricta in the tint of the wings, which is unimportant perhaps, 

 but constant so far as we know (5 $ of each examined); also in 

 the proportionate width of the band and terminal space, but 

 chiefly by its uniformly larger size and different coloration be- 

 neath. 



C. EROSA. n. s. 



?. Entire insect pale, lustrous chestnut brown, with a tinge 

 of ochre on the primaries and thorax. Secondaries rather darker 

 than primaries. 



Anterior wings crossed by two very oblique, nearly parallel 

 darker lines ; the inner one straight ; the outer one somewhat 

 bent towards the base of the wing as it approaches the inner 

 margin. The space enclosed by these lines is wider than the ter- 

 minal area. Fringes of all the wings dark, same color as the 

 transverse lines. Outer margin of primaries distinctly concave at 

 termination of 4th median nervule. 



Beneath, uniform pale lustrous red-brown, fringes darker. 

 The outer line on the primaries above faintly visible. 

 $. Similar to ? but smaller. 



Expanse of wings $ 0.95, ? 1.40 inches; Length of body $ 

 0.40, ? 0.65 inch. 



I (5 4 s examined. Collected by Mr. Henry Edwards in. 

 Oregon. These were raised from larvae which had been feeding 

 on Robinia pseudo-acacia, and which had spun up in a number of 

 leaves drawn together. The larva is yet unknown, but the male 

 of this species is abundantly distinct from the male of C. distria, 

 the only species with which it could be confounded.
