OF NORTH AMERICA. 11 



$ . 5 . — Type, black with yellow and ochraceous spots. Head bright 

 reddish ochre. Palpi and antennae black, the former reddish ochre be- 

 neath. Prothorax black with a small sulphur yellow spot on each side. 

 Patagia sulphur yellow, edged with black. Thorax black with a small 

 reddish ochre spot behind. Legs black, inside of anterior and middle 

 pairs largely red ochre. Apical half of posterior tibiae yellow, which 

 prevails also largely on tarsi. Abdomen black above and below, with 

 the tip, and indications at the sides of each segment, of narrow trans- 

 verse bands of reddish ochre. 



Anterior wings deep velvety black, with twenty to twenty-two clear 

 yellow spots, disposed as follows : five at the base of the wing, (being 

 two above the subcostal vein, two below the median vein, and one in 

 the discal area); a double spot on the middle of the costa; beyond this, 

 across the nervules, an oblique band of four unequal ovate spots, di- 

 vided, by the black nervules; between these and the inner margin are 

 two rounded spots; finally the nervules are crossed by an outer sinuated 

 band of eight spots, those next the costa being very minute. Between 

 the two middle spots of the four which lie below the median vein, there 

 is frequently present a narrow transverse spot. 



Posterior wings black, with reddish ochre markings as follows : an 

 irregular median band broken in the middle, connecting on the costa 

 with an inner transverse spot ; faint indications of tw^o or three basal 

 spots, and an outer band of spots touching the anal angle where the 

 spots are confluent. 



Van ocliracea, (pi. 3, fig. 2,) differs in the colorof the abdomen, and 

 under wings, which are clear yellow ochre. The abdomen is black 

 below, ochreous above, with narrow transverse black bands, sometimes 

 more or less confluent at the base. On the posterior wings the black 

 area is reduced to a submedian band, a transverse spot on the costa, 

 an extra median band deeply emarginate in the middle, and traces near 

 the apex of a black marginal band. The main nervules are frequently 

 black in the outer portion of the wings. Var. guttata (pi. 3, fig. 3), 

 resembles the type, except that the abdomen is entirely black, except the 

 tip; and the secondaries are uniform black, except a few small reddish 

 ochre spots, variable in number, near the outer margin, which are all 

 that remain of the typical markings. 



Expanse of wings, 2.20 inches. Length of body, 0.90 inch. 



Habitat. — California, (Coll. Edwards, Behr, etc.) 



Larva. — The body is black; the first three segments are clothed with 

 dense rust-red hairs; the remaining segments with very long silky white
