American species so far as known to me. So the clubs of the two 

 are precisely alike. But on the under side there is a departure 

 from Leonardiis, which has distinct spots on secondaries. In 

 color and lack of spots Straton resembles Arpa. 



A NEW SPECIES OF ANTARCTIA FROM MOUNT HOOD, 



OREGON. 



By B. Neumoegen. 



Antarctia rubra, n. sp. 



$ Head and thorax remarkably pilose and of bright blood 

 orange color. Head prominent, thorax very stout, abdomen of 

 short, conical structure, less hairy, and of lighter color. Antennae 

 prominent, of same color as head and thorax, with black, even 

 pectinations. Legs concolorous with thorax. 



Primaries chocolate color with a reddish underground. 

 Fringes orange color intermixed with brown. No special mark- 

 ings, except a small blackish discal spot, hardly perceptible. 



Secondaries smoky black with orange tinted, bright fringes, 

 and a diminutive black discal spot. 



Beneath, primaries as well as secondaries reddish bro7/n, 

 fading into a lighter, whitish shade towards base, and fringes of 

 a prominent reddish tint. Discal spots in primaries and second- 

 aries, well marked in black.

 very small, black discal spot.

 wings. Fringes concolorous. 



Expanse of wings, ^ i i-io inches; ? ij^ inches. 



Length of bodies, $ % inch ; ? ^ inch.

Having convinced myself that I had not to deal with the red 

 California variation of A. punctata. Pack., which, by the way, 

 occurs only in the female form, I decided to study Boisduval's 

 description of California Arctians, especially A. rufula, before 

 pronouncing on the present species. I came to the conclusion 

 that A. Rufula, Boisd., $ (vide Lepid. de la California, p. 80.) is 

 nothing but one of the numerous varieties of A. vagans, Boisd.^
