290 AMERICAN MICRO-]. EPIDOPTERA. 



Liitliocolletis inartiella sp. nov. 

 Plate XXI, Fig. 19. 



Antenni© brownisb gray. Face and palpi yellowish white. Scales of the tuft 

 pale brownish ocherons, darker toward the tips. 



Thorax and forewings deep reddish safi'ron. A rather broad median white 

 basal streak, ending at one-third the wing length, is faintly dark margined above 

 and at its apex. Just before the middle of the wing is a curved white fascia 

 margined on the inner side with brown scales and shading into the ground color 

 on the outer side. Beyond this are three costal and two dorsal white streaks, 

 margined interuallj' with brown scales, the last costal and dorsal streaks but 

 faintly so. The first dorsal streak, which begins opposite the wedge-shaped, per- 

 pendicular first costal streak, is oblique, its apex directed toward the a])ex of the 

 second costal streak. Second dorsal streak above the tornus, points toward the 

 second costal streak. In the apical portion of the wing, just below the third cos- 

 tal streak, is a conspicuous black apical dot. A dark brown marginal line in the 

 cilia, which are pale grayish brown at the apex, becoming darker toward the 

 tornus. Alar expanse 6.8 mm. 



Hindwings and cilia brownish gray. Abdomen dark brownish gray. Legs 

 pale brownish gray, tarsi unspotted. 



Type.— Male, No. 12003, U. S. Nat. Mus. 



A single specimen of this very distinct species was l)red by Dr. 

 Harrison G. Dyar at Kaslo, B. C. Record number 21563, the food 

 plant being given with some doubt as birch, which is, howevei', 

 probably correct, as the species bears a close relationship to the 

 European birch feeding species, ulmij'oliella Hb.

 Antennfe dark gray, whitish at the apices. Face and palpi pale golden. Tuft 

 dark. brown mixed with white scales. 



Thorax and forewings deep shining reddish saflTron. A very nariow line 

 across the patagia is continuous with a broader basal streak, whidi is white with 

 a golden lustre. The basal streak, ending at oue-tliird the wing length, is dark 

 margined above and indistinotly so beneath. On the dorsal margin, just before 

 the apex of the basal streak is a small broad wliite spot. Just before the middle 

 of the wing, is a nearly straight fascia, distinctly margined ou its inner side with 

 black, and with a few scales on the outer side. Beyond the fascia are two pair 

 of streaks, of which the two costal and the first dorsal are black margined inter- 

 nally. The first pair of streaks are large, triangular and placed nearly jierpen- 

 dicular, the dorsal just before the tornus with its apex between the first and sec- 

 ond costal streaks. The second dorsal streak above the tornus is small and oppo- 

 site the second costal streak. Beyond them, the apical portion of the wing is
