only reaches half-way through cell, where it runs into a large patch of 

 brownish scales on the upper half of outer quarter. A narrow line 

 of brown scales runs through upper half of cell from oblique line 

 to outward patch. From the third from costa geminated spot a 

 lustrous white line runs below the costa and before apex turns down 

 to ocellic patch; from second spot before apex a shorter line of the 

 same scales runs into the first line. Ocellic patch large, lustrous 

 white inwardly, with two or three black dots on each side, a smaller 

 white spot just l)elow middle of outer margin and a smaller white dot 

 below this, the latter onl}' separated from the large white patch by 

 a black line; al)ove the latter and between the large patch and 

 outer margin is a small round spot of ground color, nearly surrounded 

 by narrow black lines; above it are three horizontal black dashes. 

 There is a broken line of black scales dividing the upper white spot, 

 thence running into anal angle through outer margin. The dorsal 

 margin is narrowly, for its entire length, marked with white and 

 fuscous scales, increasing to a triangular patch in the middle (where 

 first spur runs into dorsum). The apical spot is Hat triangular inclosed 

 in white. Cilia and outer margin light gray, closely speckled with 

 light broAvn. Hind wings fuscous, cilia paler, same beneath. Under- 

 side forewing fuscous, with white costal dots repeated. Abdomen 

 fuscous, legs whitish, tarsi annulated with light brown. Expanse 

 11.5 to 13.5 mm. 



Nine specimens: Tryon, North Carolina (Fiske); Washington, 

 District of Columbia, June and July (Busck); Fortress Monroe, Vir- 

 ginia, July 19 (Kearfott).

1 should jjlace this species in the cataclystimui group, and close to 

 unhr/dana Fernald, which it somewhat resembles, but is much smaller. 



EUCOSMA GIGANTEANA Riley. 



Four specimens, August 5 to 27. 



EUCOSMA JUNCTICILIANA Walker. 



One male, August 13. Agrees with the Eastern form of this species, 

 in which the oblique median line has a small outward hump about its 

 middle, while all of the Northwestern and Calif ornian specimens I have 

 seen has this line perfectly even on its outer edge. 



EUCOSMA ABRUPTANA Walsingham. 



Three specimens: June '2, July 5, and August 18. These dates show 

 a rather long period of emergence. The insect is probably single 

 brooded and the larvae borers or internal feeders like allied species.
