OF NORTH AMERICA. 75 



Anterior wings pale yellowish, with black spots disposed as follows : 

 two basal longitudinal ones ; two sub-quadrate ones on the costa, 

 followed by a triangular one near the apex, and a small sublunate one 

 at the extreme apex. A triangular spot on the middle of the outer 

 margin with its base outward, and two others between it and the anal 

 angle with their bases inwards. The first quadrate costal spot has a 

 small portion detached by the light median vein, and opposite it near 

 the inner margin is another sub-quadrate spot. Between the second 

 quadrate costal spot and the inner margin, are two very narrow trans- 

 verse spots. Fringes and all the margins of the wings narrowly and 

 neatly yellowish. Posterior wings white, with the inner margins 

 rosy red. 



? . — Similar to the S except that the black "on the abdomen is 

 more prominent, and the lower wings are entirely rosy red, with a 

 faint discal and an outer band of four black spots, of which three are 

 subcordate with the points outward, the fourth, (being the second 

 from the apex) triangular with the base outward. Fringes pale rosy red. 



Expanse of wings, 1.70 inches. Length 0/ body, 0.7c inch. 



Habitat. — California, (Coll. H. Edwards.) 



Of this handsome and characteristic species I have seen but one 6 ? , 

 both to taken in southern California. While Boisduval's description 

 is somewhat vague as to the markings of the primaries, which in this 

 genus are notoriously difficult to describe in words ; the words " lower 

 wings white, with the abdominal gutter red," and his reference to the 

 red secondaries of the ? , satisfy me that the insect here figured is the 

 same described by that writer, who states that he has received the male 

 also from Mexico. 



2 -ARCTIA BEHEII N. S. (PI. 3, fig. 12 5 , 11 $ . ) 



i . — Head, thorax, paiagia and abdomen below black. Abdomen 

 above pale orange, with the terminal segment, and a dorsal row of 

 transverse spots black. 



Anterior wings velvety black, marked as follows with pale ochraceous 

 yellow : a narrow longitudinal streak reaching nearly to the outer 

 margin, between the median and internal veins, and a narrow edging 

 to the inner margin. A broad basal band, and two submedian bands 

 reaching from the costa to the inner margin where they nearly unite. 

 In addition there is the usual outer angulated band, originating on 

 the costa, midway between the outer band and the apex of the wing.
