of wing nearly or quite of the same cinnamon-rod as tiie 

 base ; next to the outer border a row of transverse white 

 spots, very indistinct or ahuost wanting at the middle, 

 larger and more conspicuous at the outer angle ; these are 

 surmounted by triangular cinnamon-red spots, bordered 

 faintly with ochraceous scales, especially that between the 

 last branches of the median and the inner border of the 

 one between subcostal and median ; adjoining the tips 

 of the triangular spots is a faint row of narrow circlets of 

 ochraceous scales enclosing cinnamon-red spots, generally 

 a little deeper in color than the base of the wing; between 

 these and the outermost black band is a very narrow faint 

 band of rosy-white scales, barely seen to be formed of 

 lunules opening outwards.

 the "Ledge," and again August 2d, at same place; at 

 the head of " Tuckerman's Ravine " August 11th, several 

 specimens were taken in good condition, and many more

 Comparative Zoology. I have never seen the caterpillar 

 or pupa ; specimens of the imago taken August 2d were 

 full of eggs, some of which, flattened by accidental pres-

 closely ribbed, and transversely wrinkled, the ribs being 

 only moderately prominent, extending to the apex, but
