Labial palpus ochreous ; base of second segment deep brown and the 

 brush suffused and profusely irrorated with brown; third segment 

 with i)oorly defined brown subbasal annulus. Head ochreous mixed 

 with brown; anterior margin of front deep brown. Thorax deep 

 purplish brown mixed with ochreous. Ground color of fore wing 

 light wood brown, shaded with deep brown on costal half at base and 

 streaked with white and black; subcostal vein black irrorated with 

 white on outer half; veins 5 to 9 indicated by black scaling; at apical 

 third a transverse, outwardly curved, crescentic, whitish fascia; at 

 basal third, in cell, an indistinct black discal spot followed by a white 

 streak, the latter confluent with the poorly defined white outer discal 

 spot at the end of cell ; vein 2 largely white with brown shading above 

 and below ; veins 3 and 4 liberally sprinkled with white, 5 sparsely so ; 

 from apical third of costa, around termen to middle of inner margin, 

 a series of poorly defined blackish spots ; cilia concolorous with slight 

 pink tinge. Hind wing and cilia pale smoky; wing darker apically 

 with blackish terminal line. Legs ochreous suffused and irrorated 

 with fuscous except at joints. Abdomen ochreous. 



Male genitalia. — Similar to alienella except that the lateral edges of 

 the anellus of artemisiella are strongly produced (see key and fig. 196). 

 The clasper of artemisiella appears to be armed with fewer and coarser 

 spines than that of alienella., but I have not seen sufficient material to 

 determine whether this character is constant. 



Female genitalia. — Similar to alienella except that the anterior 

 edge of ostial opening is convex in artemisiella but slightly cleft in 

 alienella. 



Alar expanse, 22 mm. 



Type. — In the Canadian National Museum. 



Type locality. — Seton Lake, Lillooet, British Columbia, Canada. 



Food plant. — Arteinisia. 



Distrihution. — Known only from the type locality. 



Remarks. — In addition to the differences in genitalia the thorax 

 in artemisiella is not white as it is in alienella and the fore wing lacks 

 the red coloration of the latter species.
