OF NORTH AMERICA. 19 



partially ochreous toward the lower end of the joint ; elsewhere the 

 legs are black or blackish. Abdomen, at base and dorsally, black, 

 laterally bright ochreous ; a segmentary series of black stigmatal spots. 

 Beneath pale ochreous with sublateral series of broad segmentary 

 maculations diminishing towards the anus. 



" Anterior wings somewhat produced at apices, black. Costal edge, 

 towards the base, pale ochreous. Nervules finely marked by pale 

 ochreous scales. An incomplete sub-basal transverse band and an 

 outwardly arcuate median band, not extending below the internal 

 nervure. A longitudinal stripe running from the base below the 

 median nervure outwardly to internal angle, before which it is furcate 

 on cell I b ; on this stripe rests terminally a series of transverse bands, 

 resembling the letter K, with the straight stroke turned towards the 

 base of the wing and the fusion of the bands (sometimes) obsolete 

 on cell 3. The short fringes are pale yellow, and extend uninterrupt- 

 edly from the apices over the rounded internal angle along internal 

 margin. Beneath the wing is paler, while the markings of the upper 

 surface are repeated, but less distinctly ; the veins are obsoletely marked 

 with pale scales. Secondaries largely black ; subterminally these show 

 irregularly shaped and elongated bright ochreous patches ; fringes as 

 on primaries. Beneath the secondaries are largely marked with bright 

 ochreous bands on a black ground." (Grote, loc. cit. ) 



? . — Same as 3 except in the smaller amount of black on the second- 

 aries, where the black spots are not confluent as in the S , but are 

 distributed as follows : one at the base, a median row of three spots, 

 an outer row of the same number, one of them touching the anal 

 angle, and a black outer margin dentate between the outer row of 

 spots.

Habitat. — California, (Coll. Boisduval, Edwards, Stretch. ) 



This insect is found in the neighbourhood of San Francisco, but 

 appears to be rare. Dr. Boisduval states that the type of this species 

 was received from Siberia, but is inclined to the opinion that this 

 locality may be erroneous, as Eschscholtz from whom he received it, 

 collected also in Russian America on the Aleutian Islands, and may 

 have taken it in the latter place. 



Arciia complicata, Walker, from Vancouver's Island, appears to be a 

 very closely allied species, even if it be not identical with A. Dahurica ;
