the inner margin. Outside of this is the usual angulated Hne, resem- 

 bling the letter z, originating on the costa midway between the outer 

 transverse band and the apex. Its first angle is somewhat distant from 

 the outer margin, its second rests on the outer median band, while 

 the third nearly touches the outer margin but does not connect with 

 the longitudinal streak. 



Posterior wings rose color, with the outer margin from the apex to 

 near the anal angle, narrowly banded with black, the inner line being 

 sinuated. Just inside of this are three small black spots. Fringes 

 yellowish. Beneath the anterior wings are paler, with the yellow mark- 

 ings broader and less clearly defined ; the posterior wings are more 

 inclined to orange, with indications of one or two discal dots, in ad- 

 dition to the markings seen above. 



The condition of the body parts of the only specimen I have seen, 

 is such as to preclude an accurate description. 



Expanse of wings, i.oo inch. Length of body, 0.40 inch. 



Habitat. — California, (Collection of Dr. Behr, from Mt. Shasta.) 



This well marked species is probably the smallest of the North 

 American Arctians. I have named it after Professor Bolander of San 

 Francisco, who, though more specially devoted to botanical studies, and 

 eminent therein, has greatly aided our knowledge of California Ento- 

 mology by collecting insects during his botanical rambles in the remote 

 districts of the State. The present species was taken by him. 



4.-ARCTIA EDWARDSII, N. S. (Pi. 3. fig. 9.) 



5. — Head prothorax and patagia pale ochreous yellow, with two 

 black spots on the prothorax, and a black dash in the centre of the 

 patagia. Thorax black, with two narrow pale ochreous stripes. Ab- 

 domen dirty red above, pale ochreous below, with the terminal segment 

 and base black, and a dorsal, lateral, and two ventral rows of black 

 spots. Legs black, outside of tibiae yellowish. 



Anterior wings black, with the costa, inner margin and veins, very 

 narrowly pale ochreous, and the following markings of the same color. 

 A narrow longitudinal streak below the median vein, forking on the 

 outer margin ; a transverse basal band slightly curved outwardly, and 

 beyond this a bifurcate median band originating on the inner margin, 

 with both branches slightly convex outwardly, and diverging towards 

 the costa in the form of the letter V ; beyond this an angulated outer
