sent me by Henry Edwards, who states that he has another identically 

 the same. 



Arctia obliterata. (^. Head beneath and palpi black; above pale yellowish, 

 with black spot between the antennze. Thorax pale yellowish, wiih two prothoracic 

 and three thoracic stripes. Abdomen black above, yellow ochre along the sides, with 

 black lateral spots; beneath whitish with two rows of black spots. Legs black; 

 femora of the anterior pair touched with ochre; outside of all the tibisc whitish. 

 Prmiaries dark blackish brown; costa, fringes and inner margin, narrowly pale 

 yellow, as well as the veins, longitudinal stripe, terminal W, and costal half of the 

 terminal band, this being all that is left of the transverse bands except traces of the 

 median. Secqndaiies dull red with black spots, the marginal and submarginal rows 

 being all present and of good size. There are faint traces of all the row of median 

 spots, but the discal one is the only one conspicuous. Base unclouded. Apical spots 

 slightly fused into a narrow apical border. Beneath, as above, but the colors paler 

 and more diffuse. 



E.^panse of wings 1.30 inch. //ad. (?) 



Described from i (^ in only fair condition, sent me many years 

 ago by W. H. Edwards, Esq. After seeing all the other American 

 Arc/tans I can refer it to none. The ornamentation of the primaries 

 places it in the Quenselii, gelida group, characterized by the presence of 

 only the costal half of the terminal band, which imparts to them a very 

 distinct character. Obliterata is however the only one in which the sec- 

 ondaries are spotted, and also the only one in which they are red. 



Arctia elongata. O . Head and palpi black, front very narrowly margined 

 with pale yellowish white. Thorax the same color, with two prothoracic and three 

 thoracic stripes which occupy nearly the entire surface. Abdomen above yellow- 

 ochre, last segment whiti.sh; terminal hairs, two lateral rows of spots, and a moder- 

 ately broad dorsal stripe, black. Thorax and abdomen beneath, black, with a few 

 pale marks on the edges of the segments of the latter. Legs imperfect in my speci- 

 men. Primaries black, markings pale yellowish white. These consist of a narrow 

 costal border not reaching beyond the median band; a similar border to the inner 

 margin and the fringes; the median vein very narrowly as far as the terminal band; 

 the longitudinal streak, terminal W, terminal and median bands both extending from 

 costa to beyond the longitudinal streak, and traces on the costa of a sub-basal band. 

 Secondaries clear ochre-yellow, with black spots. All four spots of the marginal and 

 sub-marginal rows are present, the costal spot of the former, and the three apical 

 spots of the latter row, being fused into a narrow apical margin. All three spots of 

 the median row present, the mner one being connected with the base by a black streak. 

 Fringes yellow. Beneath, similar to the upper surface, but colors less pronounced. 



Expanse of wings 1.55 inch. Hab. Spokane Falls, Washington 

 Territory. 



Described from one female in good preservation except the legs and 

 antennae. Collected by Mr. Ricksecker and presented to me by Mr. 

 Rivers of Oakland, California. The species is very distinct. In shape
